Spanish architecture firm Selgas Cano recently unveiled their new spectacular office in Madrid, who are also winners of this month’s incomprehensible architects website award. Located within a forest, the tube-like structure is half-sunken into the ground, giving the illusion of complete isolation. The low impact on the surrounding area is wonderful, as is the huge continuous windows letting natural light flood in

A large window runs the entire length of the structure and forms part of the roof, ensuring workers a panoramic view of the surrounding woods. The office is entered via a partially-hidden stairwell and has retractible shutters at the end of the structure. Selgas Cano’s design is photographed by world-renowned dutch architecture photographer Iwan Baan.
