Office building L'Alliance - Braine L'Alleud


This building was constructed observing all of the conditions required for a BREEAM-certified building and aimed to be graded Excellent. The V-shaped block is a passive building whose superstructure covers +/- 6,100 m². It blends into the grounds of the Alliance, both in terms of appearance and quality, and floor areas and materials used.

The building includes:

  • a basement, used for parking, cloakrooms, technical facilities and archives;
  • 4 floors above ground;
  • a floor for technical facilities in the roof.

The building's two wings are joined via an internal corridor.
Each floor may be divided into 2, or even 3 sets of leased premises, each with its own washroom and technical facilities.
Parking ratio: 1/35 m² of constructed office space in the superstructure, about 1/3 of which is outdoors.

Passive building.

Since 1998 Franki has been part of Willemen Groep, the largest family construction group in Belgium.
