Demolition Killarney Heights: Steep Sandstone Blocks, Done Safely

Slope, sandstone and the waterway

On a steep Killarney Heights block, the council’s siting and geotechnical controls come to the front. Northern Beaches Council’s development control plan applies provisions covering steep land, landslip risk and building on difficult topography, and separately controls for land near the waterway and its erosion and drainage, given the peninsula’s position above Bantry Bay and the Garigal reserves. For a demolition, that can mean the method and sequence matter as much as the machine: retaining, staged removal and protecting the slope and any waterway below are part of doing the job safely rather than an afterthought.

The correct in-force planning instrument for this part of the beaches is the Warringah Local Environmental Plan 2011, and it is worth getting right, because some listings cite an instrument that is not in force. The council also has a consolidated Northern Beaches plan on public exhibition, so we confirm the in-force controls at the time of your job. Where bushfire mapping applies, it is a further constraint we account for rather than the lead. Our tight-access and hand-demolition approach, and non-destructive digging for locating services before any excavation, are what these blocks call for.

What we take down in Killarney Heights

Killarney Heights is established freestanding homes on sloping, treed, water-adjacent blocks, so the work leans residential and technical:

• Full house demolition and knockdown-rebuild site preparation
• Partial and internal demolition, including single-wall removals
• Swimming pool removal and site restoration
• Shed, garage and outbuilding removal
• Site clearing and careful excavation on steep ground

On steep or tight blocks we use hand-demolition specialists and non-destructive digging where machinery cannot safely work, and we notify neighbours before we begin.
