Greisch office has a department charged with total design of buildings. The presence of a team of architects alongside the engineers enables to maintain a constant contact with architectural creation, its formal or aesthetic concerns, its specific modes of invention and the exploration of appropriate technical solutions that it requires. The commissions entrusted to Greisch office enable it to develop its own conception of architecture. This is always guided by a search for economy of resources, structural simplicity and efficiency and is dominated by the determination to offer a greater quantity and quality of space to users at the same price. Several faculty buildings for the University of Liège epitomise this approach, which exudes a style of its own. The concern to use a limited number of simple and economic materials, use of visible structures, easy to understand and perfectly executed, the formal purity that promotes functional efficiency and the attentive and elegant solution of the tiniest detail characterise the firm's architecture. Greisch office built its own offices, producing a building to accommodate its team and, at the same time, symbolising the mentality that drives it together with its conception of architecture.
In the beginning of 2004, BEG split the engineering and the architecture activities. The last have been entrusted to CANEVAS, a new partnership. This architectural office holds architect, engineer-architects and draftsmen whom the greater part has worked together with René Greisch during several years.
