Affordable design

This model was produced for the purpose of being able to carry out a cost analysis and calculate the energy that is necessary to maintain the property in the form of heating, ventilation, lighting and hot water (this excludes personal consumption).

The figures are modelled around a 2-bedroom detached house with a footprint of 9.3m x 5.3m offering approximately 77m² of habitable space and having only mains-connected electricity and water supply (no gas).

All other components to complete construction.

all prices are approximate component supply cost only, exclude site/build insurance, hire goods, installation/labour and VAT
