Quick Answer
A home extension in Gledswood Hills costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Camden Council approvals, and construction under one fixed-price contract.
Gledswood Hills Home Extensions & Additions
A home extension in Gledswood Hills gets the straight answer — the 2010s+ master-planned stock is young, and most plans here still work. I knock back more briefs in this estate than I take.
Where the family genuinely outgrew the home, the 350 to 550m² blocks take a designed-to-the-metre rear addition, with estate guidelines checked and clay junctions engineered.
At the $1.1M to $1.5M range, the targeted wing can beat trading up beside the golf-course estate.
We build these fixed-price, licence HBL 487805C. Spell out what you need and I will give you the honest read.
Buildana manages the complete home extension process in Gledswood Hills — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Most homes don't need it yet
Gledswood Hills' homes are mostly under a decade old with plans that already work — and I say so rather than sell a wing nobody needs.
The honest exceptions: a home bought small, a family that grew, a plan that is truly out of room.
Precise where it proceeds
Compact blocks leave no slack, so the wing is designed to the metre — guidelines checked, junctions engineered, each metre earning its place.
Every metre is priced up front, designed before you commit.

How It Works
From First Call to Final Key
Free consultation at your Gledswood Hills home. We inspect the existing structure, check Camden Council's controls, measure available space, and discuss what you need.
⏱Two design moves are usually on the table: match the existing house so the extension reads as original, or contrast with it so the new section is clearly modern. Both work — choice is aesthetic, and we'll show 3D renders of both before you commit.
⏱CDC (10–15 business days) or DA through Camden Council depending on scope. Structural engineering, BASIX, and all documentation prepared and lodged.
⏱Construction phase connects new to existing — footings, frame, roof tie-in, waterproofing at junction, internal fit-out and external finish. Staged works minimise disruption to your daily routine in Gledswood Hills.
⏱Final inspection focuses on the integration: paint blend, flooring transitions, ceiling height, junction waterproofing, sound transmission. The extension shouldn't feel bolted on — it should feel like the house was always meant to be this size.
⏱Quality Promise
Every Buildana home extension in Gledswood Hills is delivered under a fixed-price contract — from design consultation through to defect-free handover.
