TYIN tegnestue Architects was established in 2008 in Norway. The office has completed several projects in poor and underdeveloped areas of Thailand, Burma, Haiti and Uganda.

TYIN tegnestue Architects are motivated by humanitarian projects. Solutions to real and fundamental challenges call for an architecture where everything serves a purpose - an architecture that follows necessity. By involving the local populace actively in both the design and building of their projects, TYIN are able to establish a framework for mutual exchange of knowledge and skills. All materials used in TYIN´s projects are collected close to the sites or purchased from local merchants.

TYIN is currently run by Masters of Architecture Andreas G. Gjertsen and Yashar Hanstad, and has its headquarters in the Norwegian city of Trondheim. The office operates out of a 1960's cargo boat, the 'Sjellsford'. Where they share the space with 2 other architects.

TYIN has won several international awards and their projects have been published and exhibited worldwide.
