ANOTHER development opportunity in Dublin's Temple Bar area comes on the market next month when Quinn Agnew offers for sale by tender a substantial building at 7/9 Aston Quay. The agents are indicating a price guide of £750,000 for the four-storey concrete-framed building, which has planning permission for extensions at first floor and roof levels. The ground floor is occupied by Simon Noone Stores trading as Liffeycraft, under a long-term lease. The upper floors, which have an area of almost 7,900 square feet, could be upgraded as offices or converted for use as a hotel or apartments.
