The pie chart shows the approach to finance for the 12 apartments and 8 houses in the development. The relative build cost has been split between the different units according to size. The actual construction cost of the homes was £1081 per square metre. Land cost was £204,000. After initial cooperative members raised a minimum of 10% deposit for each of the individually allocated equity shares, the resulting mortgage to Lilac was £1.5 Million.
The environmental credentials of the scheme are evident in many different aspects, ranging from the innovative construction method and the use of ‘Modcell’ pre-fabricated straw bale insulated panels, an integrated sustainable urban drainage system, shared allotments and pocket park, to the incorporation of renewal energy technologies. Indeed, the environmental performance of the building fabric ensures low energy and low running costs, with the availability of the Feed in Tariff (FiT) for the photovoltaic panels covering the energy running cots of the common house. It is also demonstrable that the approach to collaborative design and collective learning in LILAC, including the performance specification and the relationship with actual rather than speculative lifestyles; has benefits in actual performance and low carbon low energy usage.
