LILAC is the UK's first affordable, ecological cohousing project. A community of 20 households and common house, the buildings are made with the ModCell prefabricated straw bale construction system, assembled by LILAC members using local straw. The excellent insulation properties of straw, combined with airtight construction, triple glazing, and heat recovery ventilation, reduce energy and CO2 emissions to a minimum. A community owned Solar Hot Water & Photovoltaic scheme reduces energy & CO2 emissions further. The site has a sustainable urban drainage system to minimise water use and run-off, and the landscape includes herb gardens and allotments shared with the wider community.
The LILAC homes have received UK Energy Performance Certification (EPC), according the SAP 2009 assessment procedure.
(Cost data includes the specific construction costs of the homes + fees & site preparation, excluding parking and urban sewerage).

ModCell Traditional Panel

Structural work / Passive system
ModCell® is one of the first products to make large-scale, carbon-negative building a commercial reality.
The ModCell® system utilises the excellent thermal insulation qualities of straw bale construction to form prefabricated panels, made in a local Flying Factory™.
ModCell® allows super-insulated, high-performance, low energy ‘passive’ buildings to be built using renewable, locally sourced, carbon sequestering materials that include straw bale and hemp to create a less than zero carbon construction system.
