The main house and tree house both have an internally exposed green oak frame with
Scottish Larch external weather board cladding and cedar shingles to the tree house
and dormer roofs. The use of a green oak frame provides a long lasting structural
solution with oak frames 300 years plus still standing.
Green oak is used both internally and externally as a structural material. The tree
house posts and edge beams are external and exposed but the structural integrity
will be maintained. Internally the oak frame is treated with oil enhancing the material
and nourishing the oak.
