Zoning at the site
Zone Z9 - DEV PLAN 2022-2028
Z9: Amenity/Open Space Lands/Green Network: To preserve, provide and improve recreational amenity, open space and ecosystem services.
Land zoned to stay open — parks, playing fields, amenity corridors. Built development is very hard to justify, which also means the view is protected.
Z1: Sustainable Residential Neighbourhoods: To protect, provide and improve residential amenities.
An established residential area. The objective is to protect existing residential amenity as well as to provide housing — which is the objective a neighbour's objection to an overbearing extension is usually argued under.
