Buildings in Sint-Pieters-Leeuw
Tailored to the buildings of Sint-Pieters-Leeuw, after an on-site survey. No obligation.
Sint-Pieters-Leeuw, also called Leeuw-Saint-Pierre, is a municipality of Flemish Brabant south-west of Brussels, at the entrance to the Pajottenland. Here you find the Coloma estate and rose garden.
The building stock is contrasting: Ruisbroek and Negenmanneke, dense and close to Anderlecht, sit alongside the villages and countryside of Vlezenbeek and Oudenaken.
Replacing windows meets varied needs: thermal insulation everywhere, acoustic comfort near the main roads and the railway.
We work throughout the municipality — for example
- Centre
- Ruisbroek
- Negenmanneke
- Vlezenbeek
- Oudenaken
- Sint-Laureins-Berchem
