Geanaisean

Geanaisean

The ambition for the house project, Geanaisean, was to deliver a certified Passivhaus using natural and healthy building materials. By coupling the Passivhaus standard with the MAKAR off-site n-Sip panel system, a huge reduction in energy demand was achieved in a healthy and sustainable manner.
As well as creating a healthy building, the timber-based construction system is beneficial to both the team working on the construction and the environment as a whole. Carbon sequestration is provided by the Scottish-grown timber kit, while the cellulose and wood fibre insulation demonstrate the use of recycled and upcycled natural products.
