A new Passivhaus set within the historic Domun Road, in Winchester. This stunning private house was built within a steep embankment after removing thousands of tonnes of chalk, soil nailing the bank and forming the space for the house to be built. The clients environmental passion required the construction to achieve Passivhaus Accreditation and they were able to obtain planning through an excellent planning application through Architecture PLB. Whilst the stunning concept was great for planning the method of construction proved to be beyond the clients budget, so Amiri were asked to sue our skills at reviewing the scheme and providing our initiatives to obtain a best value solution within budget. As well as the method of soil nailing separating the bank from the building, we offered an offsite solution for the building envelope. The difficult logistics for this project meant designing components that could be delivered, off loaded and erected within the narrow historic road and erected (avoiding overhead cables) to the unusual plot. We designed and installed a bespoke pre cast ground beam solution that sat on minimal site pad foundations. This then supported a panel form of construction. The panels were predominantly pre finished in the factory before erection and the envelope was built in only 3 weeks. The high standard of finish was complemented by the excellent specification and a real passion to deliver an exemplary product.
