Opposite Office straps one-square-metre studio to tree in Weimar

architecture-design · 2026-08-28

In Weimar, Germany, the architecture firm Opposite Office has unveiled the Baumhaus Office, an innovative work space measuring just one square meter. Designed to address soaring rental prices in Munich, the office accommodates three architects and features essential furnishings including a desk and shelves. Constructed from spruce wood and plywood, the treehouse is finished with aluminum cladding and boasts a dome-shaped skylight. Benedikt Hartl, the firm’s founder, views the structure as both a functional office and a commentary on the real estate market. The university has granted temporary approval for the treehouse, which may be relocated in the future.
