High Trees


Greenbox Associates have worked with Ken Wingate of Made in Place Architects on his own Passivhaus retrofit and extension project in Bognor Regis, West Sussex. This 1960's detached property was very energy inefficent, typical of a property of this time and the internal layout has been improved.

The house has been modelled in PHPP and the construction details amended to meet the requirements of the PassivHaus Enerphit standard. The new design has a Passivhaus design stage certificate which is the first step in achieving overall EnerPHit certification

The refurbishment works are currently underway, and the PHPP files are being reviewed by the certifiers.
