Ercle were approached by a self builder who had purchased a site with planning in order to redesign the building to Passivhaus standard. The site was an infill site with difficult neighbours who were vociferous in their complaints about anything being builton the site. Working within difficult constraints the project was realised to a high design standard.
Although not formally tested to achieve Passivhaus accreditation the building meets the standard. The clients only complaint is that he installed underfloor heating throughout and has yet to turn it on.
