Local studio Anttinen Oiva Architects has designed the mass-timber Katajanokan Laituri building in Helsinki as the headquarters for timber supplier Stora Enso. Katajanokan Laituri houses the headquarters of the Stora Enso forestry company along with the 164-room Katajanokka Pier 4 Hotel and a restaurant. …As the headquarters of mass-timber supplier Stora Enso, the building was designed to showcase the company’s products. The architecture studio used around 7,600 cubic metres of spruce and ash to create the structure, mostly composed of almost 2,500 pieces of cross-laminated timber and laminated veneer lumber. “Katajanokan Laituri is a solid wood office and hotel building that sets an example for the possibilities of wood construction in a sensitive urban environment,” said the architecture studio. “The project was guided by the objective of minimising climate impacts over a long lifecycle and making the best use of renewable resources and materials.”
