Nyth Pren is one of our exemplar sustainable houses. As a new build house in a wide open space in Rhoscefnhir, Anglesey, we have been able to optimise orientation relative to the sun. It uses straw bale insulation to achieve passivhaus levels of insulation. Both air source heat pump and photovoltaic panels are utilised as renewable energy sources. The cladding is locally sourced cedar, which will reduce the carbon footprint of this project.
