A finished rear extension in West London

Everything we do

Thirty-one services. One contractor.

A renovation needs a structural engineer, a plumber, an electrician, a tiler, a carpenter and a decorator. Most people end up managing six companies and every gap between them. Here is the entire list, on one page, all of it ours.

Construction, structural & civils

The jobs that change the shape or the structure of the building. Every one needs drawings, calculations and a building control sign-off, all of it done in-house.

Building services

Everything that runs through the building or protects it from the weather — and the services people only think about when they fail.

Why it matters that it's all ours

One extension pulls in eleven of these.

This isn't a list to look impressive. It's a list because a single job quietly needs most of it, and every name on it is another company to chase if it isn't us.

  1. Drawings & planning
  2. Structural calculations
  3. Groundworks
  4. Underpinning
  5. Steels
  6. Drainage
  7. Roof & glazing
  8. Electrical
  9. Plumbing
  10. Tiling
  11. Joinery
  12. Decorating

One contract, one schedule of works, one point of responsibility. When something is found behind a wall — and on a London house something always is — nobody stands in your hallway explaining that it's the other trade's problem.

  • A written schedule of works and payments before anything starts
