Facade of a Haussmannian-style building in Brussels to be converted into housing.

The Brussels City Land Registry is launching the Fleurs project, aiming to transform a 19th-century Haussmannian office building into housing and expand an existing commercial space, in a dense urban area near Place De Brouckère.

The Fleurs project, led by the Brussels City Land Registry, involves the conversion of several buildings into housing. These properties are located in a dense, mixed-use urban fabric, in immediate proximity to Place De Brouckère, an area characterized by residential, commercial, and facility functions.
The project's scope covers a built area within a block between Rue aux Fleurs and Boulevard Émile Jacqmain. It includes a Haussmannian-style building dating from the late 19th century, listed in the architectural heritage inventory of the Brussels-Capital Region. The work focuses exclusively on interior modifications, fully preserving the exterior appearance and architectural features.
The intervention aims to transform the first-floor office space into a 3-bedroom apartment. It also includes extending the ground-floor commercial space into the garden level of the neighboring building at number 23, Rue aux Fleurs.
On the Rue aux Fleurs side (numbers 23 to 27), the project plans to partially redevelop former workshops and storage areas into 4 single-family homes, thereby strengthening the residential function within the block. The program includes 2 three-bedroom houses and 2 four-bedroom houses.
New access points for the individual houses will be created from Rue aux Fleurs, which will also host the entrance to the storage area and 3 garages. Bicycle parking spaces are provided for each dwelling. The apartment is accessible from Boulevard Émile Jacqmain.
The project aligns with a sustainable approach, emphasizing the preservation of existing structures and minimizing heavy interventions to reduce the environmental footprint. Sound existing structures are maintained and, where possible, reused in a circular economy logic.
The work primarily aims to improve the energy performance and comfort of the housing units through insulation, envelope optimization, and the use of materials compatible with old buildings. The shared garden in the center of the block is preserved as is.
