This comprised of a semi basement extension and a V-Tec green roof. The strength and insulation properties of Sunbloc insulated concrete formwork and V-Tec made this the go to choice for the owners, utilizing local trades to help them complete the build. 

The roof to the extension now forms part of the garden, a testament to the load bearing capacity of V-Tec flooring. Skylights let natural light into the extension which are set into the V-Tec roof.
