Roughan & O’Donovan provided civil and structural engineering design services for this urban regeneration scheme comprising 1000m² of new build and 1000m² of refurbishment in the heart of historic Dublin.


New build

We were responsible for the design of a new highly serviced, steel framed, 4-storey office building situated adjacent to two 2/3-storey buildings.

We minimised underpinning to the existing buildings by using a foundation consisting of pad footings with integrated ground beams to counter eccentric column loadings.

We maximised the available service zone within the ceiling of the new building by using Comdek cold-formed metal flooring with a concrete topping and asymmetrical steel beams (ASBs).


Refurbishment of two 2/3-storey buildings was extensive and included:

  • Removal of the asbestos roofing material
  • Installation of a Kingspan cladding system
  • Cleaning, painting and repair of trusses
  • Replacement of roof purlins
  • Construction of a new mezzanine floor

Site works

Existing drainage and external services were upgraded to incorporate sustainable drainage measures, including rainwater harvesting.

Surface water run-off from the site was attenuated to the original greenfield run-off rates from the site with excess water being stored to accommodate the 1 in 100 year storm event.


  • A very tight site 
  • Location within a historic area 
  • Occupied protected structures surrounding the site
