Located in the center of Rotterdam, the Timmerhuis is a new building for the city hall that accommodates services, offices, residential units, shops, and parking. Attached to another municipal building from 1953, the new building adjusts to its neighbor by keeping the same floor slab levels. The project is generated as a repetition of modular units gradually set back from the street as they rise into two irregular peaks. The building’s composition of smaller cells creates a complex and impressive shape, but whose presence is perfectly moderated with the setbacks. The innovative structural system generates maximum efficiency and versatility: units can adapt either office space or residential parameters, and units can be added or dismounted as the demands on the building change over time. The structure consists of three-dimensional Vierendeel beams, that free up the street space creating an open public plinth towards the city. The brief asked for a sustainable building, achieved through two large atriums connected to a climate system that stores warmth and cold to control temperature as required. The facade uses hi-tech translucent insulation that allows for energy efficiency.
