Sixteen to twenty-four weeks, described honestly.
Every stage, what it actually looks like living through it, and exactly when money moves. Nothing here is skipped, including the stages that aren't glamorous.
- Weeks 0–2
Consultation & concept design
An unhurried first visit, followed by concept drawings and an honest feasibility view within two weeks.
- Weeks 2–8
Design development & planning
Detailed drawings, structural engineering, and — where required — the planning application or Larger Home Extension prior approval. Conservation area and listed building conversations happen here.
Paperwork, not disruption - Weeks 8–10
Groundworks & foundations
Excavation and foundation pours. Machinery on site, but contained to the footprint of the new build.
- Weeks 10–14
Steel frame & shell
Structural steel goes up, the shell takes shape, and the roof structure is closed in. The loudest, dustiest stretch of the whole build.
The disruptive weeks - Weeks 14–17
Glazing & roof lantern
Bespoke steel and frameless glazing installed — ordered in week two specifically so it arrives on programme, not late.
- Weeks 17–20
First fix
Electrics, plumbing, insulation and plastering. Interior work only from this point — the disruptive outdoor stages are behind you.
- Weeks 20–23
Bespoke joinery & second fix
Kitchen, flooring, and joinery built and fitted by our own workshop — drawn for this room specifically, not a catalogue range.
- Weeks 23–24
Snagging & handover
A joint walkthrough to catch anything before sign-off, and the building control completion certificate.
Six stages. Nothing paid before it's earned.
Four protections, all checkable.
Section 75 style cover
Payments beyond your deposit go against completed, inspected stages you can see — never a milestone we set ourselves.

Ten years, in your name, issued by the insurer — covered even if we stopped trading.
Proof of insurance
£10m public liability plus professional indemnity, provided before groundworks begin.
Written contract
Scope, price and payment stages fixed in writing before any deposit is taken.
