this bespoke glazing, along with the rest of the windows and doors was supplied and fitted by 21° (formerly Green Building Store). Besides accommodating curves, The Pump House features a long list of ‘green’ credentials – something that’s due to John and Debra’s own high sustainability ambitions and also to meet the planning permission conditions for the site. The Ultra Range windows and doors, for example, have helped achieve an annual kWh/m2


figure that surpasses the assivhaus


standard, while the majority of the windows are deliberately south facing to take advantage of solar gain and provide warmth in the winter. The couple’s new house has an SAP (standard assessment procedure) score of 121 and an Agrade  energy performance certificate. hile most of the property’s roofing is u a substantial area has been given over to a green roof that’s seeded with a mix of meadow wildflowers. A litre rainwater harvesting system supplies water for roof and garden irrigation – and for all the WCs and the washing machine. Solar  panels feed a esla owerwall 2 battery, which enables the export of excess solar electricity to the grid and off-grid power at night or during a power cut.


High levels of insulation and airtightness, combined with mechanical ventilation and heat recovery equipment, means near constant


internal temperatures – whatever the external temperature. John reveals: “We have been able to maintain comfortable internal temperatures when the temperature outside has been below 0°C and as high as 30°C without the use of heating or air conditioning.


e adds nderfloor heating has been installed throughout, but we’ve not needed to use it so far. Hot water and heating, if required, is provided by a 12 kW air source heat pump.” The Pump House has also been designed in compliance with the specifications of the Lifetime Homes Standards, which requires, among other things, wide doors, level thresholds and space for a home office. The build was conducted with rigid compliance to waste management standards which resulted in less than 2% of the waste generated during construction ending up in landfill while the planting of more than  herbaceous and medicinal plants bulbs trees and shrubs has helped to increase the biodiversity of the site. ith all work finally completed in  ohn and Debra are now enjoying the results, living at the property with their two adult children. Their new home, set in beautiful countryside that is just a 10-minute drive from Brighton, has 380m2 of living space and includes five bedrooms one of which is currently being used as an office.
