Successful ‘Tweed’ office development

Didier Van Den Eynde

The ‘Tweed’ office building developed by Macan Group and recently delivered in Brussels pentagon can be considered as a benchmark for an office development. A strategic partnership with the powerful institutional partner AG Real Estate made it possible to finance and carried out this 75 million Euros development project.

The project consisted of the demolition of an office building (formerly Vivaqua headquarters) built in the 1960s, and its reconstruction with the objective of providing a building that meets current standards: passive, modular, flexible, bright and with high environmental performance. An ingenious and successful rebuild carried out by Interbuild Group with the collaboration of the engineering firm Sweco.

‘Tweed’ offers now 16,500 m² of spacious offices spread over 11 floors around an atrium bathed in natural light. Panoramic terraces offer breath-taking views of the south of Brussels and Brussels Court house. The stunning architecture is the work of Altiplan architects.

Tweed is now fully let to top class tenants (DLA Piper law firm,, Inditex, Immoweb, Stepstone and a Spaces hybrid business centre). According to L’Echo, average lease length is 10 years at a rental level of between 230 and 260 Euros/m²/year. This development has been well sold via an off-market transaction to the Caisse des Dépôts & Consignations (CDC) and BNP Paribas REIM.

At the environmental, Tweed has attracted BREEAM ‘Excellent’ certification and a ‘passive building’ status. Where urban mobility is concerned, the building benefits from a first-rate level of accessibility, especially by public transport.
