Outrigger is a new build 4 bedroom eco-house located on a sloping site in Polzeath, Cornwall. The accommodation is arranged over three floors. The entrance is on the ground floor with access to the basement bedroom level below and an open plan living area above via an open stairwell. The dwelling has far reaching views to the north over the beach and sea. The architecture of the new house reflects the regional vernacular of the area utilising a similar form, scale and palette of materials. It is located between an existing period residence and a 1960s built dormer bungalow on a very tight site.

 

The dwelling has been designed to the AECB CarbonLite – Silver standard which is comparable to the Code for Sustainable Homes, Code 4. The dwelling is traditionally constructed (high thermal mass) to ensure that the building stays naturally cool in the summer with high levels of insulation and high-performance doors and triple-glazed windows to ensure it is energy efficient in the winter.

 

The south facing glazed area allows natural daylight into the open glazed stairwell whilst allowing passive solar energy to be utilised within the dwelling to reduce its energy load. Ground Source Heat Pump heated (underfloor heating and hot water) with a whole house Heat Recovery Ventilation System. It achieved an SAP 2005 / Energy Performance Certificate, Energy Efficiency Rating of 81 and Environmental Impact (CO2) Rating of 88; reasonably low due to its exposed coastal location. Its combined estimated energy use is 78 KWh/mÇ per year; total 15600 kWh per year.
