The competition – organised by the Brussels ‘Bouwmeester’ chief architect – seeks proposals to transform the offices of Crelan, which was founded in 1937 and operates around 600 branches, into a new residential complex. The phased €22.9 million ‘Westpark’ project will convert the large office block next to Westland shopping centre in Anderlecht into a ‘sustainable, innovative, and inclusive place to live.’ Intended as a single long-term investment and an alternative to the traditional housing market, the project – backed by developer GML ESTATE – will prioritise shared spaces, affordability and a sustainable management model.Advertisement According to the brief: ‘The project is guided by strong principles of sustainability and circularity. Preserving the existing structure will prevent unnecessary demolition and minimize its ecological footprint, as by using reclaimed materials and applying circular construction principles. ‘Architecture will play a key role in the success of this transformation. The goal is to create a recognizable and well-integrated residential complex while offering a variety of housing types suitable for a diverse population, including young families, seniors, and people with reduced mobility. ‘Improved insulation and the reduction of thermal bridges will enhance the building’s energy performance, while repurposing the underground levels will ensure optimal space management.’ Crelan’s occupation of the 10,000m² office building on the western fringes of Brussels is due to end in 2028. Planned to complete in early 2030, the building’s conversion will deliver an estimated 120 apartments plus new green spaces close to the Brussels Ring road. The latest procurement comes two years after an open international contest was held to create a new €60 million-to-€80 million stadium for Belgian football club Royale Union Saint-Gilloise.Advertisement Caruso St John and Bovenbouw Architectuur transformed the insurance firm Royale Belge's former headquarters into a multi-use building, including a hotel, workspaces and gym in 2023.
