Built for work, made for craft

One shell, many fits.

An insulated, pre-wired, open-plan 36m² space — no kitchen or bathroom to design around. A few of the briefs we build for most often:

Home office
A quiet, lockable workspace separate from the main house — finished and ready to occupy.
Music room
Insulated walls and ceiling help contain sound — set up for practice, lessons, or home recording.
Workshop
Pre-wired open floor for tools, benches, and projects that need their own dedicated space.
Art studio
Bright, open floor for painting, sculpture, photography or any creative practice that needs room.
Home gym
A solid, clear-span floor that takes racks, mats and equipment — no internal walls to plan around.
Guest room
Self-contained accommodation for visitors without giving up a room inside the main house.
