Malone O’Regan was the Civil and Structural Design Consultant for the development. The site was categorized as a green field with mains water trunk sewers traversing the site. To maximise the site potential, Malone O’Regan developed a design to divert the large diameter sewers. This work was completed successfully under the supervision of Malone O’Regan and Fingal County Council. The integrated estate contains 270 homes in 43 buildings varying from two-storey terraced housing to 4 storey apartment blocks. The development also contains an Estate office, a Community Building, a Group Home, a Creche and a Playground. Parnell Estate is a mixed tenure estate with some homes managed by the housing association and the remainder managed privately on behalf of Fingal County Council. The Tolka Valley soil strata is Till on gravely Clays from the Quaternary Sediments. The Pinkeen River a tributary of the River Tolka bounds the southern boundary. Steep sloping embankments descend to the Pinkeen River. The site characteristics required an assessment of the Valley embankments to support new buildings. A grid of piles and ground beams supported the taller buildings, while the lower and lighter buildings were founded on traditional strip foundations. The superstructure is traditional load-bearing masonry supporting precast floor slabs and lightweight steel roofing.
