Lewes ECO Open Houses

Address: 1a Middle Way, Nevill, Lewes, BN7 1NH
New condensing boiler
Cavity wall insulation
1a Middle Way is an unusual bungalow, located in an isolated plot, up a roadway leading off Middle Way. Tony and Wilma bought the house in 2010 and immediately undertook modernising and renovation works, including expansion into the roof. The cavity walls had been insulated but the roof has gone from no insulation to maximum. Existing double glazing has been retained and 2.3kW of solar PV is now generating electricity. In the sitting room a woodburning stove has been installed, which is heavily used in winter, greatly reducing gas consumption. By undertaking relatively simple and cost effective measures, emissions have been cut substantially. Although this house is twice the size of an average UK house, its emissions are 40% less.
Tony and Wilma are particularly committed to all aspects of sustainability and have fitted five water butts around the house to minimise mains water use for watering. They also pump bath water to the garden, rather than waste it. Composting is done using a Green Johanna hot composter, which ensures rapid breakdown. They have also planted fruit trees and established a corner for vegetable production.
Woodburning stove – Heat would circulate better if this could have been sited centrally, rather than at the end of the building, but that was the logical place for the sitting room.
Underfloor insulation – This might have been done at the building stage, but was considered difficult and disruptive. Now that flooring is in place it is not possible to do this until the next major refurbishment in many years time.
Solar thermal – Solar thermal would have been difficult, especially as the house has a combi and no water storage.
