Proposed development

Permission is sought for amendments to a previously approved development (Reg. Ref. 3269/23). The proposed amendments comprise the following: • Provision of a new 9sqm L.V. room and 8sqm ESB kiosk to the south-west of the site, adjacent to the existing main entrance; • Removal of the two existing inner security gates; • Installation of photovoltaic (PV) solar panels on the roof of the approved two-storey extension; • Increase in the height of the roof-level plant room of the proposed two-storey extension from +45.200 m to +46.100 m, and relocation of the structure to achieve a 2.9 m setback from the north-east elevation. The enclosed area, providing space for the water tank, plant equipment, and required maintenance access, will also increase in footprint from 20 sqm to 44 sqm; • Modifications to the ground-floor student toilet windows on the north-east elevation of the proposed two-storey extension; and • Enlargement of the stair window located above the escape doors on the north-east elevation.
