A PRICE of £550,000 is now being sought for a newly restored office building at Bachelors Walk, Dublin 1, after it failed to sell at tender. Joint agents Lisney and Hooke & MacDonald are involved in negotiations with a number of parties for the four-storey over basement house, which dates from 1750. The 3,500-square-foot building was restored by Zoe Developments as a condition of the planning permission for 300 apartments, which have been sold on an adjoining site.
