During its 25 years in business, two distinct areas of expertise have developed at 3dO arkitekter. The first is municipal and healthcare spaces with specialist knowledge in logistics and materials suitable for the unique requirements, and the second area is private accommodation and hotels –contrasting, yet with similar demands on understanding the visions and needs of the users, and interpreting what is left unsaid. A project that has attracted attention is nursery school Ugglan in Botkyrka, which has won the Metal Prize and is used as a great example of a well-executed process for architecture students.
