5. Prior to commencement of development, the developer shall submit, for the written agreement of the planning authority, the following revised and/or additional details: (a) Roof plan — the retention of the existing two chimneys and capping stones on the gable and the central valley, the rainwater down pipes and the hopper heads. Natural slate Bangor Blue coverings and clay ridge tiles shall be used in the roofing works to match the original slate coverings. All roof work shall be executed by a contractor with expertise in the roofing of historic buildings. (b) Historic timber sash windows and surrounds — original windows shall be retained, repaired, draught-proofed and repainted. Slim double glazing or laminated historic glass may be considered for the historic frames, if required, where no historic glazing exists, or a secondary glazing system may be permissible, subject to agreement with the planning authority. (c) Front elevation decoupling — the decoupling of number 19 from the adjoining building shall be carefully executed to avoid any damage to the decorative brick and stone pier on the right-hand side of the single entrance door, which extends beyond the joint line between the brick facade of number 19 and the adjoining building. This is likely to necessitate the incorporation of the entirety of the party wall between the two buildings to ensure that the ground floor pier and stone dressings are retained in its entirety and in an authentic manner. A revised 1:50 proposed elevation and section of number 19 shall be submitted to the planning authority to include a margin of brickwork that will fully support the brick pier and stone dressings and may include quoins to match those on the corner of the building onto Eastmoreland Lane. (d) Historic shopfront — the shopfront shall be sensitively restored in accordance with best conservation practice and Dublin City Council Shopfront Guidelines and shall include the careful removal of the existing vent in the glazed over panel above the double entrance doors. The developer shall investigate, through careful opening up, whether historic fascia board and signage survives behind the vertical timber boarding, and, if it exists, this shall be incorporated into the proposed development. The historic timber double and single doors to the shop front shall be retained, repaired and refurbished in accordance with best conservation practice. (e) Brickwork and stonework — sound historic lime pointing shall be retained. New repairs shall match the existing pointing technique and materials. Marked-up drawings shall be submitted to the planning authority when the building has been inspected at close quarters, indicating proposed repointing and repairs to brickwork, cornice, window surrounds, shopfront and other features. (f) Stone cleaning —abrasive blasting techniques shall not be used to clean the stone dressings. A cleaning sample shall be prepared using a light-touch low pressure steam clean for the inspection and agreement of the planning authority. (g) Rainwater goods and drainage pipework — a revised drawing of pipework on the east elevation (drawing number 2119-PA-050/A 1:50 Elevations Sheet 1 and drawing number 2110-PA-051/A 1:50 Elevations Sheet 2) shall be submitted for the written agreement of the planning authority. (h) Waterproofing — the use of applied repellents shall be avoided. The building shall be properly repointed using a lime mortar and all sources of water ingress such as leaking downpipes or hopper heads shall be addressed. Reason: In the interest of the protection of architectural heritage in accordance with the provisions of the Architectural Heritage Protection Guidelines for Planning Authorities.
