What we do

Roughan & O'Donovan works with architects, developers, local authorities and property owners to develop robust, long-lasting building designs.

Our buildings achieve the top certifications within sustainable design, including LEED and BREEAM. 

Retail developments, office buildings, schools and hospital facilities feature strongly in our portfolio.

We design robust, long-lasting buildings that people are happy to be in.


We adopt a proactive approach to design and use the latest technologies and techniques, including Building Information Modelling (BIM), to deliver projects on-time and within budget.


We are more than just experts in buildings.

We offer a wide range of integrated, specialist services across the building lifecycle, including:

  • Environmental 
  • Planning
  • Ecology
  • Hydrology
  • Geotechnical
  • Transportation 
  • Valhalla is an exemplar architectural, social and sustainable design.
