Questions about your Rose Bay project.
Do all Rose Bay houses have the same flood constraints?
No. Use current information for the exact property. The catchment study is a starting point for enquiries, not a declaration that every address has the same risk or required floor level.
Can we keep an interwar façade and modernise inside?
That is an option to investigate with the building’s condition and any heritage controls in mind. The layout, structural openings and retained details should be considered together.
Should a hillside extension always have a basement?
No. Compare the usefulness of that space with excavation, structure, drainage and access requirements. A stepped or smaller addition may suit the brief better.
