Federation cottage and terrace additions in Waverley/Charing Cross/Bondi/North Bondi, beachfront heritage-grade work on Bondi Beach, cliff-top additions on Tamarama and Bronte. Suspended slabs, substantial retaining, salt-grade specs on coastal builds. Heritage Council expects retention of stained glass, cast-iron lacework, ornate plasterwork, slate roofing, sandstone walling on protected streets. Realistic budget $400K–$1.2M for thoughtful 60–130m² addition; $800K–$2.5M for premium beachfront/clifftop heritage-grade work on Bondi Beach/Tamarama/Bronte. Pre-construction 6–9 months.

Home Extension Waverley — frequently asked questions
Do I need DA approval for a home extension in Waverley?
Most extensions exceeding 50m² floor area or altering envelope require DA in Waverley. Smaller compliant additions may use CDC fast-track. Heritage Conservation Areas require DA regardless of size. Buildana assesses your scope at proposal stage and provides the planning pathway in writing.
What does a second-storey addition cost in Waverley?
Second-storey additions in Waverley typically run $300K–$1.4M depending on footprint, structural reinforcement to existing footings, heritage overlay, and finish specification. Buildana provides fixed-price contracts after structural assessment.
Can I stay in the home during construction?
Most ground-floor rear extensions can be staged so you remain in the existing home during major works. Second-storey additions usually require temporary relocation for 4–8 weeks during structural and roofing works. Buildana confirms the staging plan at contract.
