One of only four detached houses on Belgrave Square, Monkstown, Co Dublin, is expected to make over £750,000 at a Sherry FitzGerald auction on September 30th. Number 39, a substantial two storey over garden level house, has around 4,300 sq ft of space and the basement level could accommodate one or two flats or offices. Three reception rooms lead off the wide downstairs hallway. Unusually, the kitchen is on the first return. There are three large bedrooms upstairs, one of which has an en suite bathroom. The garden level has four good-sized rooms.
