Saorsa, Ardnamurchan
New build on the Ardnamurchan peninsular aiming to be net zero carbon. The PH15 element of the build is off-set by us through tree planting.
This site is almost as isolated as our project on Eigg with all materials arriving via the narrow lane that runs out to Ardnamurchan lighthouse – featuring toward the end of the shipping forecast so you may be asleep by the time they mention it.
The poor form factor (due to vaulted living space) and exposed position made this a very challenging project to achieve the passivhaus standard.
