How it came together
- 01
The Challenge
A single-storey rear extension with solid brick walls was the coldest room in the property — the thermal performance was poor and the bare brick finish was well past its best.
- 02
Our Approach
Insulation boards were mechanically fixed around the full extension perimeter with careful detailing at window reveals, the door frame and the eaves. A reinforced base coat and cream protective coating completed the system, tying the extension's finish into the main house.
- 03
The Result
A noticeably warmer room with cold corners eliminated, and a fresh cream elevation that sits comfortably with the rest of the property rather than reading as an afterthought.
