New homes, one coordinated plan
As an experienced builder, Prohaus takes on residential new build projects across Kingston upon Thames and south-west London. We coordinate the build from groundworks to finishing and work to the approved drawings, engineering details and agreed specification.

New build and garden buildings
We build to your architect’s approved drawings and coordinate the trades in sequence.
Groundworks and foundations
Site preparation, drainage and foundations to the engineer’s design.
Structure
Brickwork, blockwork, steel and timber frame, floors and roof.
Windows and glazing
Aluminium and timber windows, sliding doors and architectural glass, supplied and fitted.
Services
Electrics, plumbing and heating, with regulated work assigned and certified as required.
Finishing
Plastering, flooring, kitchens, bathrooms, joinery and decoration.
Garden offices
Detached brick garden buildings, as at Maple Road in Surbiton, built on ground-screw foundations.
Building from the ground up

What we need to review a new build
- The site address and ownership position
- Whether planning permission is in place, and its conditions
- Architect’s drawings and any technical reports
- The structural engineer’s design, if available
- The intended specification and finish
- Warranty, insurance or lender requirements
Where information is missing, the first step is to work out what must be prepared before a reliable price can be given. We would rather say that clearly than price on guesswork.
Why one team matters on a new build
A new build needs every trade in the right order. We coordinate electricians, plumbers, carpenters, bricklayers, tilers and decorators as one project team.
We work with your architect and structural engineer and coordinate building control inspections through each stage.
- Prohaus Ltd was registered in 2015, and the team brings more than 20 years of residential building experience.
- Every project runs under a written, agreed contract.
- Completed work comes with a 1-year guarantee.
How new builds are priced
Every new build is priced from the approved drawings, the engineer’s design and the specification. We provide a written, itemised quotation.

Frequently asked questions
How is a new build project managed?
The approved drawings, engineering details, specification, quotation and programme are reviewed together. Any project-specific warranty, insurance or lender requirements must be agreed in writing before work starts.
Can you help if I do not have planning permission yet?
Yes. We work closely with architects and designers who help with planning and building regulations approval, and we can review the project at an early stage.
Do you build garden offices?
Yes. We built a detached brick garden office on Maple Road in Surbiton, on ground-screw foundations. Many garden offices can be built under permitted development.
What should I send with a new build enquiry?
The site address, planning status, drawings, any technical reports and a short description of the building and finish you want.
