Replacement Dwelling Siting Requirements
A replacement dwelling must be sited within the established curtilage of the existing building unless the curtilage is too restricted or an alternative nearby position would provide demonstrable landscape, heritage, access or amenity benefits.
The proposed replacement dwelling should be sited within the established curtilage of the existing building, unless either (a) the curtilage is so restricted that it could not reasonably accommodate a modest sized dwelling, or (b) it can be shown that an alternative position nearby would result in demonstrable landscape, heritage, access or amenity benefits.
