Buildings in Braine-l’Alleud
Tailored to the buildings of Braine-l’Alleud, after an on-site survey. No obligation.
Braine-l’Alleud is an affluent, dynamic residential municipality neighbouring Waterloo. Its territory blends a lively centre, vast residential districts and green spaces, including the historic site of the Lion’s Mound.
People here renovate both recent villas and older houses: replacing windows aims for thermal comfort, good looks and property value.
The roads towards the ring and the station are busy; elsewhere, the residential districts are quiet and leafy.
We work throughout the municipality — for example
- Centre
- Lillois
- Ophain
- Bois-Seigneur-Isaac
- Le Paradis
Which windows, which glazing for your street
Villa or quiet residential district
PVC or aluminium with high-performance double glazing, and aluminium large windows to open the rooms onto the garden.
