Proposal

Non Material Amendment for planning permission - 26/00611/FUL - (Single storey rear extension and loft conversion including velux windows to front and a rear dormer) Existing stairway window: Retention of the existing side window opening, with the existing window replaced by a fixed, single-pane clear-glazed unit. The existing opening, size and position are retained. The replacement window is to be fixed rather than opening for safety reasons adjacent to the proposed staircase. Rear dormer: Adjustment of the front face of the approved rear dormer by approximately 150 mm to align with and bear directly onto the existing masonry wall below, following detailed structural coordination. The approved dormer parapet, roof form and overall design remain otherwise unchanged.
