About Us

Hartwood Oak Buildings was founded in August 1994 by Sam McCallum and Tim Green. We specialise in the manufacture of traditional and contemporary green oak timber framed buildings and structures.

All our frames are individually crafted, making each one unique. We offer a full design service and have a network of architects that we work with on more complex projects.

Our goal is to provide the very best quality oak framed buildings along with a very high standard of after care service.
