The complete revitalisation of a 1960's deckhouse into a highly sustainable holiday home, involving stripping back to the frame, super-insulating and making it air tight to a standard in excess of new-build regulations. Thermally efficient windows with integral blinds minimise heat loss and control unwanted solar gains. On the roof a 2.1 Kwp photovoltaic array and an evacuated tube solar collector provide renewable electricity and hot water with excess power exported to the grid. The interior incorporates extensive use of bespoke built-in furniture, inspired by yacht design, with a limited palette of materials and full height openings to make the compact 50m2 layout feel spacious and light. The refurbished Deckhouse creates a sustainable 'staycation' solution providing carbon neutral holiday accommodation for up to seventeen weeks each year. Sustainability targets are achieved through the following: -2.1 kwp photovoltaic panels -Solar water heating -High level of insulation -Airtight construction
