A SITE of 6.5 acres at Kinsealy Lane, within two miles of Malahide, is expected to make in excess of £150,000 when it is auctioned on July 16th by Sherry FitzGerald. Although the land is zoned for agricultural use, a low density residential development is open for consideration. Moreover, all mains services are adjacent to the site. In the city, M. Cullen has been refused planning permission for 114 apartments in four-storey blocks fronting on to Conygham Road and eight-storeys over-looking the River Liffey at Dublin 8.
