Featured Project

Little Lutterburn

This contemporary addition transforms the layout of the compact dwelling, creating a vaulted ply lined entrance with a feature staircase, broken plan reception spaces and a new master suite at first floor. Clad in zinc and cedar, this new element has open gables drawing light deep into the plan. On the edge of a conservation area in the South Hams the project connects the house to its garden and creates a light and relaxed home.
