PassivHaus


A certified “PassivHaus” might look like a normal house, but it’s much more than that.

Comfortable – constant internal temperature
Healthy – internal air is constantly circulated and filtered
Quiet – triple glazed windows
Economic – about 90% lower energy costs than a conventional build

Llwyn Onn (Ash Grove) has the added benefit of being reviewed by the Design Commission for Wales




The large windows in the southern elevation flood the interior with light and contribute to the overall energy efficiency




The layout makes full use of the sloping site with south facing gardens which is ideal for a Passivhaus development.
