How it works

From a photo of your house to a decision you can defend.

Ten stages, the first three free. Every stage is labelled for what it is — observed, estimated or unknown.

1. 01 · Property

   Upload a photo of the back of your house

   Taken on your phone is fine. Daylight, the whole rear elevation in frame, a little of the garden.

2. 02 · Understand

   We read what is visible

   House form, materials, roof, windows, any earlier extension — labelled as observed, so you can correct it.

3. 03 · Visualise

   See concepts on your actual house

   Your house is masked and preserved; only the extension is drawn in. Three free previews.

4. 04 · Explore

   Tell us what you want

   Objectives, rough measurements, budget and a planning checklist. Anything you don’t know stays unknown.

5. 05 · Assess

   Options sized for your house

   Extension types that suit your house and priorities, with indicative width, depth, floor area and a concept layout.

6. 06 · Estimate

   The whole project budget

   Construction plus fees, engineering, survey, planning, contingency, kitchen and external works — low, typical and higher-complexity.

7. 07 · Planning

   Screened against the exemption conditions

   A likely route, a confidence level and the specific issues to verify.

8. 08 · Compare

   A decision matrix

   Space, budget, garden impact, planning and complexity side by side — and the option that looks strongest, with reasons.

9. 09 · Decide

   A report you can act on

   A print-ready report with questions for your architect and builder, risks, assumptions and next steps.

10. 10 · Engage

    Arrive prepared

    Take it to your first architect or builder meeting. We don’t sell your details or take referral fees.
