Our building services
We specialise in five types of work, all for homeowners in South West London. Each one is run by a dedicated project lead from the first visit to handover.
Which project adds the space you need?
| Basement conversion | Kitchen extension | Loft conversion | High-end refurbishment | New build | |
|---|---|---|---|---|---|
| Best for | A whole new floor without losing garden | A bigger kitchen and family space | Extra bedrooms and a bathroom | Transforming a whole home to a premium finish | A brand-new home on a cleared or infill plot |
| Space gained | Up to the full footprint of the house | Usually 10 to 30 m² | Usually one or two rooms | Better use of existing space | A whole new house |
| Planning permission | Usually needed in London | Often permitted development | Often permitted development | Rarely needed, unless listed | Always needed |
| Party wall notice | Almost always | Often | Usually on terraces | Sometimes | Often, on tight London plots |
| Typical build time | 24 to 32 weeks | 12 to 16 weeks | 8 to 14 weeks | 16 to 26 weeks | 40 to 60 weeks |
| Can you stay at home? | Usually, with some disruption | Usually, with a temporary kitchen | Usually | Depends on scope | No, unless the plot is separate from your home |

Most of our work comes from recommendations. Here is what a few of our clients have said.
"From the first visit to handover, the team was organised, tidy and honest about costs. Our basement is beautifully finished and completely dry, and our neighbours were kept informed throughout."
Sarah, Battersea SW11 · Basement conversion
"We stripped our Victorian terrace back to the brick and the team handled everything: steelwork, rewiring, joinery, the lot. They restored the original cornicing and the house has never looked better."
James, Clapham SW4 · Full refurbishment
"Our side return extension finished on schedule and the steel-framed doors are stunning. Every change we asked for was priced up front, so there were no surprises at the end."
Priya, Balham SW12 · Kitchen extension
