THE BUILD

Building

The physical build, documented stage by stage rather than only showing the finished rooms.

Groundworks

Excavation, foundations and getting the project out of the ground.

Structure

Walls, steels, openings and the point where the extension began to take shape.

Roof & windows

Making the structure weather-tight and choosing the main external elements.

Inside

Services, insulation, plastering, flooring and the route towards a finished room.
