A note from the studio

The most expensive mistakes in any building are made on paper. Then they're poured in concrete.

Picture this. The slab is poured. The walls are up. You climb your new staircase for the first time, and you duck.

The ceiling above the sixth step sits at 1.86 metres. On the drawings it was a neat little line that nobody questioned. On site, fixing it means cutting into a concrete slab, changing the stair, and paying for the privilege.

And it's never just the stair. Problems like these hide in plans of every size:

Kitchen0.80 m between island and counterTwo people can't pass.
PoolSliding door 0.40 m from the waterNo barrier, small children.
CaféThe lunchtime queue blocks the doorCustomers walk past.
MallAnchor store hidden from the entranceShoppers never find it.
HospitalTwo beds can't pass in the corridorEvery day, every shift.
StadiumThe concourse jams at half-timeSixty thousand people, one corner.

Mistakes like these are common, and almost invisible on paper. Not because architects are careless. Because a plan is drawn from above, and nobody lives up there.

You'll live in it, work in it or sell it for decades. So far you've only seen it from the ceiling.

The 1-10-100 rule

Everyone who builds learns it, usually the hard way: a change is cheapest on paper, costs more once building starts, and costs the most after you move in. It's a rule of thumb, not a law of physics, but anyone who has paid for a change order knows the direction is right.

10–25%of a construction project's cost is lost to avoidable errors once hidden costs are counted, by the industry's own estimate. Many start in design.1
37%of US homeowners who set a renovation budget in 2025 went over it. Nearly a third of them had changed the plan mid-project.2
1 : 10 : 100What the same change costs on paper, during building, and after handover.

So we built the Private Viewing.

Walk through the finished building first, at eye level, at a human pace, with someone beside you who knows exactly what to look for. Not a glossy render from its one flattering corner: every space, the way you'll actually use it.

The Private Viewing

This is what your walkthrough feels like.

A sample villa. Scroll slowly, and follow the narrator from the garden to the top of the stairs.

  1. 01 · Arrival
    "We're in the garden at six in the evening. The low sun sets the whole facade glowing, and the upper floor reaches out over the glass to keep the living room in shade."
    • Overhang above the living-room glass: shade without blinds.
    • No covered route from the car to the door. In a downpour, you'll arrive soaked.
  2. 02 · Living room
    "Step inside. Nine metres of glass open the whole room to the pool. By ten in the morning, daylight reaches the back wall."
    • Daylighting (natural light) deep into the room, and an open indoor-outdoor flow.
    • The slider opens 0.40 m (16") from the water's edge. With small children, that's a real safety risk.
  3. 03 · Kitchen
    "Beautiful island, seats four, a clear view to the garden. Now watch what happens when two people cook at once."
    • Clear sightline (what you see from where you stand) from the stove to the garden.
    • Clearance (free space) of 0.80 m (31") between island and counter. Two people can't pass; about 1.07 m (42") is the usual guide.
  4. 04 · Stair
    "Up we go. Floating oak treads, light pouring through. And mind your head on the sixth step. I mean it."
    • Open treads keep the hall bright and light.
    • Headroom above the sixth step is 1.86 m (6'1"). Many codes ask for about 2 m (6'7"). Tall guests will hit their heads.
  5. 05 · The whole house
    "Back up to the bird's-eye view. Every room furnished and to scale. Your list now holds twenty-three findings, ranked worst first, each with the question to ask your architect."
    • Good zoning: living, sleeping and service areas sit apart.
    • No utility room. The washing machine and drying rack end up in the kitchen.

Now imagine this is your building.

Big projects

Building big? This is where a Private Viewing pays for itself.

On a tower, a mall or a stadium, one missed detail repeats on every floor, in every unit and at every gate. We find it while it's still a line on a drawing, before it's priced, built and multiplied.

A sample office tower at duskOffices & towers
"It's 8:55 on a Monday. Four hundred people arrive in the next ten minutes. Let's watch the lift lobby."
  • Double-height lobby: daylight, and a clear line of sight to the lifts.
  • At peak, the lift queue backs up past the security gates.
Preview my tower
A sample shopping mall atriumMalls & marketplaces
"Saturday, three o'clock. You've just stepped off the escalator. Now try to find the anchor store."
  • The skylight pulls daylight three levels down into the atrium.
  • From the main entrance, the anchor store's sign is hidden behind the escalators.
Preview my mall
A sample stadium at duskStadiums & arenas
"Final whistle. Sixty thousand people stand up at once. Follow them to the gates."
  • Every lower-tier seat keeps a clear sightline to the near touchline.
  • The concourse narrows to 4 metres at one corner. That's where the crowd will jam.

What arrives in your inbox

Everything you need to fix it on paper, in about 48 hours.

At a well-known studio, a 60-second walkthrough takes about a week, and that's after the 3D model already exists. Your complete Private Viewing, model included, arrives in about 48 hours from complete plans, because we do one job, every day, and our render capacity scales with your building.

Every question, answered straight

Before you send anything.

Your plans and your privacy

Is it safe to send you my plans? Who sees them?

Only your producer and our production system. Your files sit in access-controlled storage, are used for your project and nothing else, and are deleted 90 days after delivery, or sooner if you ask. We'll sign a mutual NDA before you send anything: ours, or yours after review. Names, plot numbers and title blocks never appear in your film, and we never show your project without your written permission.

Who are you, and why should I trust a studio I've never heard of?

Pale Axis CGI Studios is an independent visualization studio working with clients worldwide. You don't need to trust us first: you see your own building before you pay anything, both guarantees are written into our terms, and the person who answers your email runs your project from first file to final film.

Can I send drawings my architect made?

Yes, for your private review. If your contract limits who may see them, we'll sign an NDA that covers your architect's work too. We never publish, share or reuse anyone's drawings.

My plans are unfinished, rough or confidential. Is that a problem?

Not at all. Early is the best time: that's when every fix still costs an eraser. Drafts, sketches with dimensions and phone photos of printouts all work. If something is missing, we tell you before the clock starts, and we list every assumption we make. Send what you have

What files do you accept?

PDF, DWG and DXF, Revit or SketchUp exports, JPG and PNG, clear phone photos, even the floor plan from a developer's brochure. A plan for each level is enough to start; elevations or sections help. Metric or imperial, any language on the drawings. Too big to attach? Send a WeTransfer, Dropbox or Google Drive link.

Price and payment

How much will it cost?

Every building is different, so every quote is fixed and written for yours, within 24 hours. Three things move the price: the size, the number of spaces, and how long you want the film. You see the exact number before anything starts, and it never changes afterwards. For context, a well-known studio charges from $30 for every second of walkthrough film, before modelling, so one minute starts at $1,800. A Pale Axis Private Viewing, model, narration and list of fixes included, costs a fraction of that. Get my quote

Is the free preview really free? What's the catch?

No catch, no card, no call. Send your plans and your quote arrives with a 15-second narrated film of your own building, ending on the first flaw we found. It's yours to keep, even if you never order. For very large projects, it covers one key space, such as the entrance, the lobby or a typical unit. It becomes the opening of your full film, so nothing is wasted if you go ahead.

Will someone chase me with sales calls?

No. You get one email with your quote and your free film. Nobody calls unless you ask for a call. If you don't reply, that's the end of it.

Do I pay anything before I've seen something?

No. You see your preview and approve your fixed quote first. Then it's half to start and half on delivery, and nothing is ever charged without your explicit yes. No card on file, no surprise charges.

How do I pay? Do I get an invoice?

By secure card payment link or bank transfer, in US dollars. You get a proper invoice for every payment, and companies and public bodies can pay against a purchase order.

What if I'm not happy?

If we got something wrong, we fix it free, always. If we find fewer than five real problems, you pay nothing and keep the film. If we're late, you get 25% off for every 12 hours, until it's free. A refund takes one message, no forms.

The film and the walkthrough

What happens after I send my plans?

Within a few hours we confirm we have everything. Within 24 hours you get your fixed quote and your free 15-second preview. You say go, and your full Private Viewing arrives in about 48 hours. Large projects get a fixed date in the quote.

What exactly do I receive?

A narrated film of every space (MP4, sharp HD, 4K on request), a walk-it-yourself 3D tour you open with one private link on any phone or laptop, stills, and your list of faults as a PDF, with a one-page agenda for your architect or designer. All yours to download and keep.

What is "walk it yourself"?

Your building as a private 3D world you can walk around in. Open one link on your phone or laptop and move through it like a video game: in through the front door, up the stairs, stand at any window, look in any direction. No app, no headset. Send the link to your partner, buyers, investors or your architect.

Do you check the design, or just make it look good?

We check it. While we build your model and walk through it, we look for faults: headroom, clearances, door swings, stairs, sightlines, daylight, privacy, flow, safety, queues and exits. Each one goes on your list with the question to take back to your architect, so you fix it before you build it. We're not your architect and we don't certify codes; our job is to make sure nothing obvious slips through.

Will the film match my plans exactly?

Every wall, opening, level and stair is built to the dimensions on your drawings. Where your plans contradict each other or leave something out, we don't guess: we flag it, and it goes on your list. Where they're silent on finishes, we keep them neutral and tell you.

Will you just criticise my architect's design?

No. The narrator is as quick to point out what's brilliant as what's risky. Every finding is a question with a sheet reference, not a verdict, and your architect keeps the final say. Most clients simply say: "I had a walkthrough made of your design. Here are my questions." With your permission, we send the list to your architect first.

Can I change things after I see it?

Yes. Your quote states how many rounds of changes are included. A round is one list of changes sent together, and each comes back within 24 hours. Corrections of our own mistakes are always free and never count as a round.

Who owns the film? Can I show it to buyers, investors or my landlord?

You do. The film, the walk-around, the stills and the list are yours to use anywhere: sales, investors, landlords, family, social media.

Can the narration be in my language?

English by default. Arabic, French, Spanish, Italian, Portuguese, Hindi, Japanese and Mandarin on request, and a second language can be added for partners or family.

My architect already made renders. Why would I need this?

Renders sell a design from its best angles. A Private Viewing questions it from every angle, at eye level, the way you'll actually use it, and hands you a written list of what to fix. Send the renders with your plans if you have them; we'll walk you through everything they don't show.

I'm an architect, designer or developer. Can I use this for my clients?

Yes. Professionals use it twice: first as a private design check before anyone else sees the scheme, then as a narrated presentation film for clients, buyers, investors or planners. Narration under your own studio name and volume terms are available on request.

How is this different from a render or a virtual tour?

A render shows one flattering angle. A virtual tour scans a building that already exists. A Private Viewing walks you through a building that doesn't exist yet, explains how it will feel, and tells you what to fix while fixing is still cheap.

Size, timing and our team

Does it work for my kind of building?

If it's drawn in 2D, yes: small homes, villas, farmhouses, townhouses, apartments, shops, restaurants, gyms, hotels, mosques, schools, hospitals, offices, towers, mini and mega malls, government buildings, arenas and stadiums. The narrator follows the people who'll use it: residents, customers, staff, patients or fans.

My project is large or urgent. Can you handle it?

Yes. Our rendering capacity scales with the job. Large projects get a fixed delivery date in your quote before you pay anything, and urgent work can be prioritised when a slot is free.

Who actually does the work?

A producer runs your project and personally reviews every frame and every finding before it reaches you. We do this one job every day, and our render capacity scales with your building, which is why it takes days, not weeks.

Can my architect or contractor actually use the list of fixes?

That's what it's for. Each finding gives the location, the sheet reference, what we saw, why it matters and a suggested question, ranked worst first.

Is this a code or engineering check?

No. We show you the building and flag design questions; your licensed architect or engineer makes the decisions and handles codes and permits.

Still deciding? Let your own plans decide for you.

What we do

One job, every day: we take the plans for a building that doesn't exist yet and let you walk through it first, at eye level, with a narrator who knows what to look for. Then we hand you a written list of everything worth taking back to your architect.

  • A narrated film of every space: how it feels, what works, what doesn't.
  • A walk-it-yourself tour on one private link, on any phone or laptop. No app.
  • Your building in 3D, furnished and to scale, with stills you can use anywhere.
  • A list of faults, worst first, each with the exact question to ask.

Who it's for

Homeowners and people buying off-plan. Developers, contractors and operators. Architects and designers who want a second pair of eyes before a client sees the scheme. Retailers, restaurateurs and hoteliers fitting out a space. Public bodies planning schools, hospitals and civic buildings. From a two-bedroom house to a stadium.

How we build it

Every Private Viewing is modelled from your drawings' own dimensions, finished with physically based materials, lit by the real sun for your site and path-traced frame by frame on GPU render nodes, so our capacity grows with the size of your building. Your walk-it-yourself tour runs in the browser on WebGL: no app and no download.

Seven faults we look for in every set of house plans

Most of the expensive surprises in a house are visible on the plans, if you know where to look. These are the seven we check first, with the question to ask your architect for each.

Pale Axis CGI Studios3 min read

A sample staircase where the ceiling above the sixth step is too low

A floor plan is drawn from above. You'll live in it at eye level. Most surprises hide in that gap: not in the big decisions, but in a few centimetres here and there that nobody checked against a real person, a real sofa or a real afternoon sun.

1. Headroom over the stairs

The classic. Where a stair runs under the floor above, the ceiling has to stay high enough to walk up without ducking. In England, Approved Document K treats 2.0 m of clear headroom over a stair as adequate. In the US, the International Residential Code asks for at least 6 ft 8 in, about 2.03 m. On the plan it's a dashed line. On site, it's a concrete slab.

Ask your architectWhere is the lowest point above the stair, and what is the clear headroom there?

2. Kitchen aisles

The gap between an island and the worktop behind it decides whether two people can cook at once. The US National Kitchen & Bath Association recommends work aisles of at least 42 in (1,067 mm) for one cook and 48 in (1,219 mm) for two or more, measured between the counter fronts, tall cabinets or appliances.

Ask your architectHow wide is the aisle between the island and the worktop, and can someone still get past when the dishwasher is open?

3. Doors that fight each other

Two doors that swing into the same corner. A bathroom door that hits the toilet. A wardrobe that can't open because the bedroom door is in the way. Every swing is drawn on the plan, but nobody walks them.

Ask your architectCan every door open fully without hitting another door, a fitting or a piece of furniture?

4. Furniture that doesn't fit

Rooms are drawn empty. The real test is whether your bed, your sofa and your dining table fit with room to walk around them, and whether they'll get through the front door and up the stairs on moving day.

Ask your architectCan we see each room furnished at real sizes, including the route the furniture takes to get there?

5. Light, hour by hour

A plan shows where the windows are. It doesn't show when the sun comes through them. A west-facing bedroom can overheat on a summer evening, and a north-facing kitchen north of the equator gets very little direct sun. We light every walkthrough with the sun's real path for your location.

Ask your architectWhich rooms get direct sun, at what times of day, and is that what we want?

6. What the front door gives away

Sightlines matter more than people expect: the first thing a guest sees when the door opens, whether the street can see into your living room at night, whether a bathroom door faces the dining table.

Ask your architectStanding at the open front door, what can a visitor see?

7. Water, glass and drops

Pools, balconies, glazing and stairs are where a layout becomes a safety question: a sliding door that opens straight onto a pool deck, a low balcony wall, a stair a toddler can reach. Most countries have specific rules for these, and they differ from place to place.

Ask your architectWhich safety rules apply to our pool, balconies, glazing and stairs, and how does the design meet them?

None of this means your architect got it wrong

Plans balance hundreds of constraints, and some problems only show up when you stand in the space. That's the point of walking through it first. In every Private Viewing, findings like these arrive in writing, ranked worst first, each with the question to ask.

Want us to check yours? Send your plans. Within 24 hours you get a fixed quote and a free 15-second film of your own building, ending on the first flaw we find.

The 1-10-100 rule: why the same fix costs more every month

A change that costs 1 on paper costs about 10 on site and about 100 after you move in. It's a rule of thumb, not a law, but the direction is right, and the industry's own numbers back it up.

Pale Axis CGI Studios2 min read

Ask anyone who has built something and you'll hear a version of the same story: the change that would have taken an afternoon at the drawing board ended up costing weeks, a skip full of broken material and an argument about who pays.

Quality managers call it the 1-10-100 rule. Catching a problem at the design stage costs 1. Catching the same problem during construction costs around 10, because now there's material to remove, trades to re-sequence and days to lose. Catching it after handover costs around 100: you either live with it, or pay to tear out finished work.

The ratios aren't precise. Sometimes it's closer to 1-5-20; sometimes one missed detail costs far more than 100. But the direction never reverses. A fix never gets cheaper as the building gets more real.

What the numbers say

The Get It Right Initiative, a UK industry group, estimates that avoidable errors cost between 10% and 25% of a construction project's cost once hidden costs are counted, and many of those errors start in design.

Homeowners feel it too. In the 2026 U.S. Houzz & Home Study, 37% of homeowners who set a renovation budget in 2025 went over it, and nearly a third of them had changed the plan mid-project.

Where the cheap changes live

  • Before permits and tender: moving a wall is a redraw.
  • Before the slab is poured: moving a stair opening or a drain is still drawing work. Afterwards, it's concrete cutting.
  • Before the walls are closed up: sockets, switches, lights and pipes can still move. Afterwards, every change means opening finished walls.
  • After handover: you're paying to undo finished work, and living around the mess.

How to use the rule

The cheapest moment to find a problem is before anyone has priced it. That's why a Private Viewing happens at the paper stage: you walk through the finished building at eye level, with a narrator pointing out what works and what doesn't, while every fix is still an eraser.

From a PDF to a walkable building: inside our process

What happens between the moment your plans arrive and the moment you walk through your own front door.

Pale Axis CGI Studios2 min read

A sample floor plan turned into a furnished 3D model, seen from above

People are often surprised that a complete walkthrough can arrive in about 48 hours. There's no trick. We do one job, every day, and our render capacity grows with your building. Here's what happens in between.

1. We read every sheet

Dimensions, levels, door and window positions, notes. If something is missing, or one drawing contradicts another, we ask you instead of guessing. A clear question now saves a wrong wall later.

2. We build the model to your dimensions

Walls, slabs, stairs, doors and windows go in at the sizes on your drawings, in Blender. Then furniture at real sizes, so you can judge every room the way you'll use it, and physically based materials, so stone reads as stone and glass reflects like glass.

3. We light it with the real sun

We set the sun's path for your site's location and orientation, at the times of day each space matters: morning in the kitchen, evening on the terrace. That's how you see which rooms glow and which stay dim.

4. We path-trace every frame on GPUs

Path tracing simulates light bouncing through the scene the way it does in reality, which is why the result looks photographed rather than drawn. It's heavy work: a two-minute film at 30 frames per second is 3,600 frames. So we render on GPU render nodes and add more as the building grows. That's how even a large project gets a fixed delivery date.

5. We walk it at a human pace

The camera moves at eye level, through every space, in the order you'd actually use them. The narrator explains how each space feels, what works and what doesn't.

6. We review every space against the same list

Headroom, clearances, door swings, furniture fit, daylight, sightlines, privacy, safety and flow, plus queues and exits on public buildings. Every finding is located, explained and ranked, with the exact question to ask your architect.

7. Your walk-it-yourself tour

The same model becomes a real-time tour that runs in your browser on WebGL. One private link on a phone, tablet or laptop: no app, no download. Walk anywhere, look anywhere, at your own pace.

8. Delivery, then deletion

Your film, tour link, stills and list of faults arrive together. Your files are deleted 90 days after delivery, or sooner if you ask.

What to send us: a five-minute checklist

You don't need a perfect set of drawings. Here's what helps, what's optional, and how to send big files.

Pale Axis CGI Studios2 min read

The short version: send whatever your architect or designer gave you. Rough or unfinished is fine, as long as it has dimensions. Early is actually the best time, because every fix still costs an eraser.

The essentials

  • A floor plan for every level, with dimensions
  • Where it is: city and country, so we can light it with the right sun
  • What it is and roughly how big: a three-bedroom villa, a 120-seat restaurant, a 30-storey office tower
  • Your stage: early design, plans approved, about to build or already building

Helpful, if you have them

  • Sections and elevations, for ceiling heights, stairs and façades
  • A site plan with a north arrow
  • Finishes, materials or mood images, if you want the film to show your choices
  • Furniture or kitchen layouts
  • Anything you're already worried about. We'll look there first

Files we accept

PDF, DWG and DXF, Revit or SketchUp exports, JPG and PNG, clear phone photos of paper drawings (flat, well lit, the whole sheet in frame), even the floor plan from a developer's brochure. Metric or imperial, any language on the drawings.

Big files

Too big to attach? Paste a WeTransfer, Dropbox or Google Drive link into your email. That works for full drawing sets and models too.

Want an NDA first?

Say so in your first email and we'll sign a mutual NDA before you send a file: ours, or yours after review. If your contract limits who may see your architect's drawings, the NDA covers their work too.

Ready? It takes about five minutes, and within 24 hours you'll have a fixed quote and a free 15-second film of your own building.

Shops, cafés and restaurants: five layout mistakes that cost sales

In a shop or restaurant, the floor plan is the business plan. These five problems are easy to miss on paper and expensive to live with.

Pale Axis CGI Studios2 min read

A sample café modelled in 3D from its floor plan

A home layout that's slightly off is an annoyance. A shop or restaurant layout that's slightly off costs money every day: in customers who walk past, tables that turn slowly and staff who walk miles. Here's what we look for.

1. The queue blocks the door

At the lunchtime peak, where does the queue go? If it snakes back to the entrance, new customers see a crowd and keep walking. Walk the plan at its busiest hour, not empty.

2. The counter can't see the door

Staff should see who walks in. A counter tucked behind a column, or facing the wrong way, loses the greeting and often the sale that follows.

3. Service crosses the customer path

Every route from kitchen to table that cuts through the queue or the entrance is a collision waiting to happen, and it slows every order.

4. The best product is hidden from the street

Passers-by decide in seconds. If the window shows shelf backs, the till or a blank wall, the shop's most persuasive asset is wasted.

5. The entrance shuts people out

A step at the door, a narrow aisle, a tight turn to the toilets: each one turns away wheelchair users, parents with buggies and delivery trolleys. In the US, the ADA Standards set a minimum clear width of 36 inches (915 mm) for walking surfaces on accessible routes. Other countries have their own rules.

How we check a commercial space

We walk every commercial space as it will be at its busiest hour: from the street, from behind the counter and from the kitchen or stockroom. Every finding goes in writing before anything is built or fitted out.

Big projects: find the crowd problems before tender

On a tower, mall, hospital or stadium, one missed detail repeats on every floor and at every gate. Here's where to look, and why walking through it beats reading it.

Pale Axis CGI Studios2 min read

A sample stadium at dusk

On a big building, design problems don't stay small. A corridor that's a little narrow is a little narrow on every floor. A sign hidden behind a column is hidden from everyone who walks in. And every one of them is priced, ordered and built before anyone stands in the space.

Towers and offices: the 8:55 problem

Lifts, lobbies and security gates are sized on paper. Walk the lobby at the morning peak and you see whether the queue backs up past the gates, and whether a first-time visitor can find reception at all.

Malls: can anyone find the anchor store?

Shoppers navigate by what they can see. From every entrance, can you see where you're going? Dead-end corridors, hidden escalators and anchor stores tucked out of view are cheap to fix on paper and permanent once built.

Stadiums and arenas: half-time and the final whistle

Your safety engineers will calculate exit widths and evacuation times, and nothing here replaces that. What a walkthrough adds is a shared picture: the whole team sees the corner where the concourse narrows, the toilet queue that spills into the walkway and the sign hidden behind a pillar, while there's still time to change them.

Hospitals and schools: the daily route

Two beds that can't pass in a corridor. A nurses' station with no line of sight to the rooms. A school entrance that jams at drop-off. These are problems you only notice by living the day, so we walk the day.

Before tender, not after

The cheapest moment is before the design is priced. After tender, every change is a variation; after construction, it's a retrofit. Walking through the building first means the people paying for it, building it and running it agree on the same building, early.

What a large-project Private Viewing includes

  • One narrated walkthrough per key space: arrival, a typical unit or floor, amenities, back of house
  • A walk-it-yourself tour for the whole team, on one private link
  • A written list of findings, ranked, each with a question for your design team
  • Mutual NDA before you send a file, purchase orders welcome, narration in your language
  • A fixed delivery date in your quote, before you pay anything

Start with one key space. Your free preview covers the entrance, the lobby or a typical unit, with a fixed quote for the rest within 24 hours.
