PDP - formerly known as Paul Davis and Partners - has completed this zero carbon housing scheme in Carryduff, Belfast
The 39 houses on the site are grouped in clusters around landscaping which features a range of private, semi-private and public spaces.
The homes have been arranged to maximise south facing facades and each feature an enclosed winter garden.
Constructed from a pre-fabricated structural timber system each house features high levels of airtightness and insulation and roofs set at 29 degrees south to achieve the maximum orientation for photovoltaic panels.
The development is the first phase of 65 homes for the site near Carryduff village.
PDP won the masterplan job through an international design competition run by Royal Society of Ulster Architects and the Northern Ireland Housing Executive in 2010.

The buildings were carefully positioned to follow the natural undulations of the landscape, tiered across the site to reduce the impact on the natural topography and character of the area.
Sound environmental design principles were employed to utilise the natural passive design opportunities on the site before the application of active systems to comply with the code. Ultimately, the creation of an exemplary sustainable community, using urban design principles that link vibrant green spaces to the dwellings and establish a community that is actively integrated into its surroundings and the village beyond.
The masterplan proposed a journey through the site around which a series of social housing clusters are arranged. The houses were designed to a specific client brief, and are layered into the landscape with private, semi-private and public open spaces. This aspires to support an ever-changing, sustainable community and cater for a variety of age groups who might occupy the development. The newly complete Phase 1 includes an extended junior play space set in wildflower meadow which is centred in the housing clusters, an amenity for residents and to promote connections with the wider community. An open village green to the ‘apex’ of the site is to follow in a future Phase 2 to complete the masterplan with landscaped edges in the form of wildflower meadow and potential allotment spaces.
The architecture of the houses is defined as much by their position on this unique site, as by the brief to achieve a Code 5 Zero Carbon rating and Lifetime Homes Standards. The site and building sections were analysed in detail all the way through the process, so that dwellings and gardens further down the hill, going north, are spaced and arranged to afford positive solar gain in the winter months, thus reducing energy demand. Each of the houses have a carefully orientated roofs set at 29 degrees south to achieve the maximum orientation for photovoltaic solar collection. The passive design strategy hinged round the use of enclosed, external, south facing winter-gardens with hard surfaces for thermal mass and tenant controlled ventilation which also provides a flexible space for the summer months.
