The scheme avoided materials which could be harmful to the environment, natural materials were selected to harmonise the building to the site. The design seeks to minimise the environmental impact, by utilising a super insulated fabric scheme integrates many sustainable initiatives to minimise carbon emissions and long term running costs. Sustainability ultimately means something that is appropriate, is loved, lasts a long time and uses very little during its lifetime. Verification concrete slab has been left exposed and polished offering the benefits of thermal mass to even out diurnal temperature fluctuations. Lane End was designed as a fabric first design. An MVHR system further reduces CO2 emissions by recycling heat from the kitchen and bathrooms and mixing this with fresh air which is circulated to colder spaces. Built to low energy standards and air tightness level of 3.5 m3/(h.m2) @50 Pa , the ground floor concrete slab has been left exposed and polished offering the benefits of thermal mass to even out diurnal temperature fluctuations. All timber cladding is sourced from renewable and local sources with British Grown Douglas Fir used internally. Bricks are hand-made locally. Ecology Landscaping was an integral aspect of the design, the existing trees on site protect and shield the house from the outside world, while the immediate landscaping creates a sympathetic and seamless transition between the inside and outside of the house throughout the seasons. The materials that were selected introduce texture to the building, using materials such as wood, brick and stone used in a contemporary way. 19 All of the standard methods have been completed such as SAP calculations and EPS ratings. The house was built to Passive House ideology, however an official certification was not sought. The approach was to create a building that was as passive as possible in its performance. We looked towards the Passivhaus standard as inspiration, however, this type of certification was not sought after by the client as it could have been too confining by design to the open dialogue with the landscape they desired. www.padstudio.co.uk Image Credit Richard Chivers
