tún is a design led architectural practice based in Dublin. It was founded in 2010 by Paul Fox, Rose Bonner Alexander and David Jameson out of a close working relationship and shared approach to design.  The practice adopts a client focused approach incorporating sustainable principals, sensitivity to context and unique creative design responses.

tún has RIAI Conservation and Health and Safety Accreditation.

The office's name comes from an Old Norse word meaning to enclose, finish or come full circle.
