Currans Hill Home Extensions — Fixed Price
A home extension in Currans Hill grows the 1990s-2000s brick home — 300 to 500m² blocks entering the age where a targeted wing genuinely adds, with the honest read given first.
The clay junctions are engineered, the estate character is respected, and the Macarthur amenity keeps the finished homes in demand.
At the $1.0M to $1.4M median, the right wing beats the friction of upsizing within the growth belt.
We build these fixed-price, licence HBL 487805C. Tell me what you need and I will give you the straight read.
Buildana manages the complete home extension process in Currans Hill — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Entering extension age
Currans Hill's brick veneer is reaching the point where families outgrow the original plan — and the rear wing or suite serves exactly that.
Where the plan still works, I say so rather than sell a wing nobody needs.
Junctions engineered
The reactive clay moves seasonally, so new footings are engineered to move with the originals at the junction.
That footing engineering is in the fixed price from the outset.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Free consultation at your Currans Hill home. We inspect the existing structure, check Camden Council's controls, measure available space, and discuss what you need. You get a clear scope, budget range, and timeline before committing. 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.
⏱The Currans Hill construction phase. Fixed price, programmed, supervised. CDC (10–15 business days) or DA through Camden Council depending on scope. Structural engineering, BASIX, and all documentation prepared and lodged. Construction Certificate obtained. 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 Currans Hill.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. 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.
