From floor plan to a home you can walk

Send a floor plan.
Walk the home.

We turn a floor plan into the home itself: true to the inch, as real as a photograph, and yours to walk through like a game. See its light at any hour, where its breeze goes, and how it lives before you build, buy or sign.

Walk it like a game

Step inside before it's built.

From the street, through the front door, past the stair and out to the pool. Every room at its true size, in the light it will really have.

Illustrative pictures of the kind of home we make. In the browser, you walk the home's own model in real time.

  • Walk, or fly over it

    At eye height with keys, a mouse or a fingertip, or turn the whole house in the air like a model on a table.

  • Up the stairs, into the elevator

    Every level is there, joined the way the drawing joins them.

  • Take a level off

    See any level from above with the one over it away, each room named with its size.

  • Morning to night

    The sun where the home really stands, and its own lights after dark.

  • Photo mode

    Stop anywhere and the browser renders the view as a still, light bouncing as it really does.

  • Opens from a link

    On a phone, a tablet or a laptop, with nothing to install. Send it to anyone.

Take the roof off

Every level, true to the inch.

We read every wall, door, window and printed dimension off the drawing, and build the home on it exactly as drawn. Then we finish it, so it looks the way it will.

  • Walls at their real thicknessDoors that swing the way they're drawn, windows at their true sills and heads.
  • Furnished at real sizesKing beds, sectionals, dining tables and kitchens that fit the rooms, or tell you they don't.
  • Finished and litOak, stone, concrete and paint; lamps, pool lights and the view outside.

The hillside house at dusk

Every hour of its light

Noon to night, as it will really be.

The sun stands where it will for the home's place, day and hour, and light bounces off walls and floors as it really does. Drag across to see the same view as the lights come on.

  • Sun, to the minute

    Where the sun is for the home's own place, on any day of the year, and which windows it reaches.

  • Daylight, in footcandles

    How bright each room is through the day, against what a room of its kind is asked to have.

  • The breeze, room by room

    Where fresh air comes in and leaves, and how many times an hour each room's air is replaced.

A floor plan is drawn to sell a home, not to live in it.

It won't tell you which rooms get the sun, where the breeze goes, or whether your bed will fit. And about one in ten printed dimensions on real plans disagrees with the drawing it's printed on.

Bedroom 312′ 7″14′ 6″13′ 6″
In the sample, Bedroom 3 is printed 12′ 7″ × 14′ 6″. The drawing says 12′ 7″ × 13′ 6″.

One report. Everything the plan leaves out.

    Bedroom 3: 12′ 7″ × 14′ 6″

    Every dimension, checked

    Each printed dimension is measured against the drawing, so a room sold bigger than it's drawn is caught before you sign.

    How it lives, scored

    Space, daylight, sun, air, layout and safety, worked out from the plan and scored out of 100 against building codes and published standards.

    What to ask, and what would help

    Plain questions for the builder or landlord, and improvements tried on the home and scored again, with typical costs.

For a project

A study of your building, made with you.

For a building you're designing or selling, we go further than the report: the rooms you care about, studied for sun, daylight, air and fit, and every revision checked against the last.

  • At a glanceEach finding first, in a word: good, watch, or falls short, and why one tap away.
  • The rooms that matterPick the rooms to study, and see their daylight through the day side by side, against what each is asked.
  • Revision by revisionSend the next drawing and see what it changed, line by line: better, worse, or a trade.
  • Private, at its own addressSealed with a password on trueinch.com, and saved as a PDF in one click.

  • Buyers and renters

    Know a home before you sign: every printed dimension checked, its light and air worked out, and a score out of 100.

    What the report gives you

How it works.

  1. Send us the floor plan.

    By email, with a few lines about the home: what it is, where it is, and what you'd like made of it.

  2. We reply with a quote.

    What we'll make, its price and a delivery date, before any work starts.

  3. We make it, you walk it.

    The home true to the inch, furnished, finished and lit, with its sun and breeze worked out, sent as a link you can share.

Your plan is used only to make your home, and is never shared.

Measured, not guessed.

  • 85%of printed sizes on 152 real plans worked out to within an inch from the drawing alone
  • 100%of the misprints planted in 128 test plans caught
  • 43 of 43test questions answered with every sentence cited

Scored under the True Inch Standard, which names the source of every level it holds a home to: a building code, a published standard or a professional body. How the True Inch Score works

Trueinch gives a plan-verified estimate, not a certified measurement.

Questions.

Can you really make all this from just a floor plan?

Yes. The plan gives us every wall, door, window and dimension; we build the home on it true to the inch, then finish, furnish and light it. Elevations, a finish schedule or photos of the lot help us match your choices more closely, but aren't needed.

What kind of floor plan works?

A builder's brochure, a listing's plan, an architect's drawing, or a phone photo of a printed plan taken straight on, in feet and inches or in meters. A PDF or an image attached to your email is best; for large files, send a link.

What does it cost, and how long does it take?

It depends on the home and what you'd like made of it. Send us the plan through your brief, or write to ceo@trueinch.com, and we'll reply with a price and a delivery date before any work starts.

Does the walkthrough work on a phone?

Yes. It opens from a link in the browser on a phone, a tablet or a laptop, with touch, a mouse or the keyboard. Nothing to install.

Is the light real?

The sun stands where it will for the home's location, on the day and at the hour you choose, and light bounces off walls and floors as it does in a real room. The report gives the same light in numbers: hours of sun and daylight in footcandles, room by room.

How accurate is it?

On 152 real plans, 85% of printed dimensions were worked out to within an inch from the drawing alone. Each report says what it measured and what it assumed. It's a plan-verified estimate, not a certified measurement: how the score works.

Is my plan private?

Yes. Your plan is used only to make your home and is never shared. What we make for you opens at its own address, with a password if you'd like one.

Do I need to sign up for anything?

No. There's nothing to sign up for or install: you email us the plan, and the home comes back as a link that opens in any browser.
