Roughan & O’Donovan provided civil and structural engineering design services for an 11-unit sheltered housing scheme on a brownfield infill development site in Clondalkin Village.


Winner of the Overall Award at the Irish Council for Social Housing Community Housing Awards 2015.


The development achieved a low U-value, a BER 'A' rating and incorporated low embodied carbon and sustainable drainage features, including a green roof.

We reduced the embodied CO2 by using environmentally beneficial concrete containing 50% GGBS and provided a building envelope with low embedded carbon using single leaf clay blocks.

External insulation with a rendered finish was applied to the entire building.

Site works included:

  • Foul and surface water drainage with permeable paving
  • Diversion of an existing large surface water sewer to clear the site for development

The development was designed to achieve best practice in sustainability and building energy consumption.

  • Valhalla is an exemplar architectural, social and sustainable design for the provision of housing for people with disabilities.
