A home extension in Pymble is one of the few places you can be genuinely ambitious, because the blocks are among the largest residential lots in Sydney — 1,000 to 1,800m² under heritage homes. On land like that a wing can be a whole new wing, not a squeezed add-on, and the garden barely registers the loss.
The controls are heavy here, particularly near the station and Avenue Road, so I check the heritage position before a line is drawn. Pre-war fabric carries lead paint alongside asbestos, both handled as licensed processes, and the finish is built to the $3.2M-plus standard the suburb takes as read.
With the PLC catchment holding families in place for the long haul, extending is simply the sensible play — you build the house out to what you need and keep the address that anchored you.
We build these fixed-price, licence HBL 487805C. Get our extension scope, with the heritage position checked, before you commit.
Buildana manages the complete home extension process in Pymble — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Room to be ambitious
Pymble's 1,000 to 1,800m² blocks let a wing be genuinely ambitious — whole living zones, guest wings, garden pavilions — behind conserved heritage frontages and with the gardens intact.
The catchment holds families for decades, so the design is drawn for that kind of horizon rather than a quick fix.
Heritage and pre-war fabric handled
The heavy heritage controls near the station and Avenue Road are checked before design, so the approval path is clear before you spend on drawings.
The pre-war lead and asbestos are removed under licence, every dollar of it in the quote from the outset.

How It Works
From First Call to Final Key
On-site assessment of your 1920s–1960s (heavy heritage stock)-era home in Pymble. We check structural condition, block dimensions (1,000–1,800m²), setback availability, and Ku-ring-gai Council's DCP requirements. Written feasibility and cost estimate provided.
⏱Designing an extension is half about the new space and half about how it joins the old one. Doorway position, ceiling height transition, floor level matching, light wells — the junction makes or breaks how the finished home feels.
⏱We lodge your extension approval — CDC for eligible designs or DA through Ku-ring-gai Council. Full documentation including structural engineering for Class M soil, BASIX, and shadow diagrams. CC issued before works start.
⏱For ground-floor rear extensions you usually stay in the house during the build, with temporary weatherproofing at the junction wall until the new section is locked up. Second-storey additions need a 4–8 week relocation during the roof-off and frame-up phase.
⏱Final inspection, Occupation Certificate, 6-year structural warranty. Your Pymble home now has the space your family needs.
