Where to start
An idea, a set of drawings,or a building to change.
The projects on this website are houses and resort buildings.
Land and an idea, but no drawings yet
We take it from the first concept through design and construction to handover.
Drawings from your own architect or engineer
We build to them.
A building that needs to change
We renovate, extend and convert existing buildings.
Several sets of drawings that have to agree
We check them against each other before and during construction, so fewer problems turn up on site.
If none of these fits, choose ‘Other’ on the inquiry form and tell us about it.
