For home owners and owner-builders

Design your own home. Build it at cost.

Bob, our AI, designs your home with you from your site and your brief, then helps you build it at the cost of materials plus assembly.

No drawing fees that run for months. No margin at every hand. Every option engineered and priced as you go, line by line.

How it works

From your address to the keys.

  1. 01

    Your site

    Start with your address.

    Bob looks up your site anywhere in the world: location, slope, the street and the local authority, with the full lot and zoning where public data exists. Or give Bob your site plan, a feature survey, a sketch or a description.

  2. 02

    Your design

    Designed with you, live.

    Tell Bob what you need. Bob designs and redesigns with you until it’s right, and every option comes engineered and priced: the structure, walls, roof and services.

  3. 03

    Your documents

    Drawings when the build needs them.

    On Build, the planning set, permit drawings, details and joinery package are released stage by stage, all from the same model.

  4. 04

    Your build

    Quotes direct from the makers.

    Bob asks the makers for quotes, keeps your build programme, and works with your council, suppliers and builder through your project’s own email, with your OK at every step.

What it costs

Know the price before you build.

Every home in Bob is priced the way it will be built: each material at its supply rate, freight to site, and the crew hours and crane days to put it together.

You see what your home is made of and what it costs to assemble. So does anyone you choose to build it.

Questions

Designing and building your own home.

Can I design my own home with AI?

Yes. Bob is an AI that designs a home with you from your site and your brief, live, and engineers and prices every option as you go. Exploring is free. Design is $49 a month, with the first ten days free.

Can I be an owner-builder with Bob?

Yes, where your state or country allows it. On Build, Bob guides you through the owner-builder path: the approvals, the drawings, the suppliers and the programme. The rules differ from place to place, and Bob looks up yours. If you would rather not, Bob finds you a registered builder.

Do I still need an engineer and a building surveyor?

Usually, yes. Bob is an AI, not a registered builder, engineer or certifier. Bob prepares the design, the drawings and the structural calculations for your engineer and building surveyor to check and sign off, and helps you find them.

How much will my home cost?

Bob prices your home as you design it: every material at its supply rate, freight to site, and the hours and crane days to assemble it. Site works, service connections, approvals and fees are separate, and Bob helps you estimate them.

What are the homes made of?

Bob designs every home for factory manufacture: a steel frame with insulated panel, stone or glass walls, every part made to measure and shipped flat, then bolted together on site.

Where can I build?

Bob designs for sites anywhere in the world and looks up the public data for yours, and searches out more on request. Building depends on local approvals, suppliers and builders, and Bob helps you through each.
