Two-storey timber extension — Bonnevoie
Case study – Two-storey timber extension in Bonnevoie

Located in the heart of Bonnevoie, this two-storey timber extension was built in a constrained urban setting. Terrexo Construct managed the complete, turnkey delivery of the project.
A lightweight, high-performance structure
Choosing a timber frame structure ensured excellent thermal performance while minimising structural load on the existing building. The extension provides 30 m² of additional living space across two floors.
