Aalto University’s library building, designed by Alvar Aalto and completed in 1970, has been renovated by Arkkitehdit NRT and JKMM. The goal of the project’s interior concept was to restore and update the modernist interiors in the upper floors of the building and to create wholly new interiors to its lower floors that were previously used as bookstores. The building metamorphosed into a multi-purpose and modern learning centre for students, faculties and other users. The services at the Learning Centre are located by themes: the protected second floor still functions as the library and reading room, Tori (marketplace) with its media walls and cafés, is situated on the first floor, and the new media services can be found on the bottom floor. It also houses spaces for studying, meeting and exhibitions.  Light has been an important factor in the overall design concept. On the upper level, where much of the Aalto interior was intact, there was abundant light making this an ideal space for exhibiting materials from the University archive. At ground level a top-lit atrium space cuts through to the basement floor enabling daylight to filter in and around the main staircase uniting the three levels. Its plentiful white pendant lighting is not only striking but will be effective in illuminating the space even in the darkest periods of the year. It works well with use of deeply coloured textiles that add a youthful sense of warmth to the interior.
