What we do
Building and civil works, from idea to handover.
We put particular weight on the right price for the quality you want, whichever form of contract you choose.
- 01
Design and build
Our main business. We usually help develop the project too, most often with the architect, and plan for the price and the building time from the start.
- 02
Main contracts
Traditional main contracts, and split contracts where the client wants them.
- 03
Project development
With particular weight on solutions, choice of materials and organisation.
- 04
Engineering and project management
We make structural assessments and calculations, and often act as design manager and project manager.
- 05
Prefabrication
Clients want shorter delivery times, so our solutions lean on prefabrication, made in-house or put together from outside suppliers.

This is a concept, so the form sends nothing. On the finished site the sender gets a confirmation straight away, and you get the enquiry at once, with the type of contract, phone number and a line about it filled in.
