The “Sustainability House” (Hållbarhetshuset/KTH 43:25) adds office space and a new small green park area in the heart of the Royal Institute of Technology (KTH) campus Stockholm, Sweden.

The building was recently awarded with first prize for Façade of the Year-prize (Årets Fasad by SPEF).

KTH, founded in 1827, is the highest-ranking university in Northern Europe in the field of engineering and technology and attracts students and researchers from around the world.

The main campus buildings designed by architect Erik Lallerstedt were completed in 1917 to 1931, decorated by prominent early 20th-century Swedish artists. The KTH motto is Sci-ence & Art, the whole campus has high cultural historical value and is protected by law.

The campus was in dire need of more office space. Since it is located within the Royal Na-tional City Park, green areas had to be preserved and space in the city plan was very lim-ited.

AIX chose to place the house on the street adjacent and transform the car park into a green campus yard. Though the volume of the building is quite big, it is perceived smaller in size due to its polygonal shape.

AIX wanted to achieve a contemporary expression inspired by the older buildings on cam-pus. The facade consists of a brick wall, built on site, with a relief to half a bricks depth.

The brick comes from Haga Brickworks (now Wienerberger) in Enköping, Swedens last remaining brick manufacturer.

The windows are placed at another half of a brick’s depth which enhances the relief of the facade further. The setting of the windows has a slight variation to give a liveliness to the facade. Each room has one narrow window without ex-terior sun shading to ensure a sense of openness.

In the entrance hall, which is shared with the neighboring house, the brick wall enters the room in an organically growing pattern. On the green roof there are solar panels.

The building consists of five floors plus basement, the width varies between 17-22 meters, adding to a total 5,650 m2 of flexible office space.

The entrance floor includes meeting rooms for conference, training and events.

The upper floors contain workplaces for the insti-tutions for sustainable development, environmental science and technology as well as real estate and construction. All plans can be adapted to changing needs for the future.
