The practice was commissioned by Habbingley Ltd to secure planning permission for Phase 2 of Fairgreen Shopping Centre in Mullingar, Co. Westmeath. The extension accounted for 16,000 sqm.  The extension included the provision of 5,040 sqm of retail floor split in 14 units, along with a fitness, medical, treatment centre and a café/restaurant, among others. Planning permission was secured after An Bord Pleanála dimissed a third party appeal.
