Façade engineering
Hotel Le Nouveau Palace is in the centre of Brussels. A metro tunnel runs under the hotel. Given this specific urban context, a far-reaching façade study was no luxury. The metro tunnel prevents a continuous foundation, as a result of which 2/3 of the building protrudes above the ground floor. The structure will partly rest on cantilever foundations as the ground on which the foundations are to be supported is at a depth of -32 m and is also partly above the metro lines that run close to the building. Therefore, more than dozens of piles will be driven into the ground at a depth of more than 35 m.
Thus, we investigated the possibilities of combining the massive appearance and materiality of the façade with the fragile balance of the primary steel structure, its inherent properties (thermal expansion, differential settlement, etc.) and the limited foundation possibilities.
The technical parameters are further complemented by comfort requirements learned from our daylighting and visual comfort studies. After this analysis, in consultation with the design team, the steel structure was provided with cladding made of prefabricated, fibre-reinforced concrete panels.
