A 2-hour site visit with client and architects of a recently completed Passivhaus build in an historic Cotswold village.
Ian Walker of CaSA Architects will guide you around the finished house and present the design process from concept through to realisation on site, explaining how they overcame the challenges of planning, technical design and Passivhaus certification, and the lessons learnt.
They will outline the thermal performance predicted using PHPP compared to actual performance data, and the client will be on hand to talk and answer questions about their experience of living in a Passivhaus.
