Old Holloway
A seductively simple self-build utilising an innovative pre-fabricated straw-bale/ timber construction. Perservering through a 4 year planning process, the single storey detached home sits snuggly within its rural surroundings.The proposal creates an informal courtyard utilising the existing huts on site and the dwelling an arrangement that is typical for the local area. The scale and massing of the simple single-storey detached dwelling, with pitched roof and south facing verandah, is sympathetic to local vernacular architecture.| Construction type | Other | Project type | New build |

Clapham Retrofit
This 4-storey semi-detached Grade II listed Victorian townhouse has been eco-retrofitted to a high standard of airtightness and thermal performance. The 170-year old, solid brick building has been internally retrofitted with over 9 types of insulation material, each a bespoke solution to localised performance requirements respecting the historic significance of the existing fabric. The existing sash windows and doors have been upgraded through the installation of double-glazed secondary glazing. High performance insulation materials together with careful airtightness and thermal bridge detailing have resulted in a historic building that is both highly energy efficient and more comfortable to live in.| Construction type | Solid Brick | Project type | Refurbishment |

2050 Now! Achieving the standards for 2050, and the potential role for innovative heating solutions in thermally improved homes
The project will be improving four homes to different levels and exploring the performance of new heating solutions to achieve the optimum balance of energy performance vs. heating input for these different technologies. The three main innovative heating technologies in this project are Baxi's Ecogen domestic CHP (dCHP), Baxi's Ambiflo ASHP and Nuaire's Sunwarm (combined positive input ventilation, solar thermal heating and solar hot water). The dCHP units will be installed in relatively worse performing households and the ASHP units in well insulated houses to understand the level of performance needed from homes to create the right environment for these technologies to achieve significant carbon savings.| Construction type | Masonry Cavity | Project type | Refurbishment |
