Woodside Social and Affordable Housing scheme, Stepaside, Co Dublin
Published 19 November 2025
This 155-unit residential development is nestled in the foothills of the Dublin mountains and provides a mix of social and affordable housing to the south Dublin area.
Managed jointly by Approved Housing Body providers, Respond and Tuath, the residential units include a mix of apartments and terraced housing, whilst a small office and community facility has also been included in the development.
The development features a range of one-, two-, and three-bedroom homes, with all 50 cost-rental units designed as two-bedroom apartments. The project was commissioned specifically to deliver both cost-rental and social housing.
The scheme incorporates a landscaped open space to the east of the apartments, providing an amenity area for residents. This public green area includes a stream along its southern boundary, which has been retained along with the established natural tree and shrub growth lining the banks. A surface water attenuation tank is located beneath this area, and an integral flow control on the outfall to the stream ensures discharge of surface water is constrained to greenfield runoff rates.
In a boost to the development’s sustainability credentials, apartment heating and hot water is served via a district heating system. This is run by an energy centre incorporating combined heat and power (CHP) units, air source heat pumps and gas-fired boilers to provide a lower carbon, energy efficient heating solution. Electricity generated by the CHP is used to supply the heat pump to meet the site’s other energy demands, and any waste heat is captured and utilised by the heating system. The heat pumps are then supplemented by the gas boilers to meet peak loads.
Waterman Moylan provided multidisciplinary support for the scheme, spanning civil, structural and building services engineering. Architects, ABK, worked closely with our mechanical engineers to maximise energy efficiency from the outset of the design process. They ensured there was a focus on optimising the building fabric, seeing elemental u-values exceed minimum compliance standards, while thermal bridging and air tightness detailing have been prioritised throughout. The combination of the excellent building fabric performance and the efficiency of the heating and ventilation systems have combined to deliver dwellings that perform to the highest environmental standards with BER ratings from A2.
