In development · United States first

Draw your building on the lot it will actually stand on.

A garage. A back addition. A first house. Sketch the floor plan the way you would sketch it on paper, watch the 3D version build itself as you draw, and set it down on your real lot — over real aerial photos, on the real ground, at the real slope. Then print drawings you can hand to a builder or an architect.

Sitebound does not exist yet. There is no download, no trial, no early access, and no waiting list to jump. It is one developer at the start of a long build. This page is here to collect your email address, and one honest answer about money.

A floor plan drawn to scale: a 24 by 26 foot accessory dwelling unit with its walls filled in solid, an open living and kitchen area, a bedroom, a bathroom with a stacked washer and dryer, and a closet. Four doors are drawn with their swing arcs, six windows sit in the wall thickness with their sills, and the line of the roof overhang runs dashed around the outside. Every door and window is tagged with its size, the kitchen shows a sink, a range and a refrigerator, dimension strings run down all four sides, and each room is tagged with its name, its size and its floor area. Under the plan a numbered bubble reads FLOOR PLAN, SCALE: 1/2 inch = 1 foot, above a graphic scale bar marked in feet. A north arrow to the right is labelled PROJECT NORTH, and a faint diagonal SITEBOUND watermark crosses the paper.

Open the whole sheet as a PDF (36 by 24 inches, 26 KB) — print it at full size and the measurements come out true.

A detail of a sheet Sitebound exported — a 24 by 26 foot accessory dwelling unit, 559 square feet of floor area, at half an inch to the foot on a 36 by 24 inch sheet: walls filled, openings dimensioned and tagged, every room's area computed. The part of Sitebound that makes the sheet is real, and this is its output, unedited. The part that will let you draw the building is still being built, so the plan behind it was written out by hand. It is a drawing, not a screenshot, and there is nothing to screenshot yet.

What you would use it for

Three things. None of them work today.

  • It starts with your lot, not a blank page.

    Type your address and your land shows up underneath you — aerial photos, real ground, the real slope. You draw your own property lines over the picture, or use a survey you already have. Then you mark how far back you are required to build from each line, and Sitebound draws that against your design so you can see whether the thing you want actually fits. Nothing here pretends to be a survey: you always know how the line got there.

  • You sketch. It builds.

    Rooms, walls, doors, windows. Draw them the way you would draw them on the back of an envelope, and the 3D version keeps up with you. Walls join themselves. Nothing you click can wreck the model, and undo always works. You should not have to learn a modeling program to find out whether your idea is any good.

  • It ends with drawings, on paper.

    Floor plans, elevations and a site plan, at a real scale with real measurements, laid out on proper sheets with a title block. Marked preliminary, because a licensed professional still has to look at them before anyone builds anything.

Being straight with you

What it will not do

The list

Join the list, and tell me what it is worth

Your email and the checkbox are all I need. The money question below is optional, and it is the most useful minute you can give me.

One confirmation email now. Then nothing until there is something real to show.

Say it worked, and you ended up with a set of drawings for the project you have in mind. What would that have been worth to you? optional

Nothing is for sale, this is not a pre-order, and no price is set. Pick what you would actually have paid. “I would only use the free version” is a real answer and I would rather have it than a polite one.

Where would you be building? optional

The first version only works in the United States — see below. Saying so means you only hear from me when it is actually relevant to you.

Double opt-in: you get one confirmation email and nothing else until you press the button on the page it takes you to. Addresses that are never confirmed are deleted after 30 days. No analytics, no cookies of ours, no tracking or advertising scripts. Privacy notice.

Three questions you should be asking

Can I use it today?

No. No download, no trial, no private beta. Nothing is finished; what exists is foundation, the parts you never see, done properly because everything you will see has to sit on them. This page is a list and a question, and calling it anything more would be a lie.

When will it be ready?

No date, deliberately — this is a multi-year build, by one person, full time. I am not going to name a quarter I would only have to move later. You will get a real date when I have one worth trusting, including if it is bad.

Why the United States only?

Because the first version puts your design on your actual parcel, and doing that honestly needs the imagery, the ground and the parcel to line up at a single address, under terms that let them appear in a drawing you can print. That chain works in one country right now. Everywhere else breaks somewhere along it; I checked properly, and it took a while. I am not going to name another country, or a date, to make this page look better. Not in the US? Join anyway and pick “Somewhere else”, and you will only hear from me if that changes. You will not be marketed a product that cannot see your lot.
