A home extension in Cecil Hills grows a home in a suburb worth staying for — quality 1980s-90s stock on generous 550 to 750m² blocks, with schools and character that hold families for decades.
The brick extends cleanly, the fabric is largely clean, and the Class H clay gets engineered footing junctions. The wing is designed to the suburb's standard — it has to match the street.
At the $1.0M to $1.3M median, the staying maths is clear.
We build these fixed-price, licence HBL 487805C. Ask us to measure what your block can hold.

Match the street
Cecil Hills' quality stock sets a standard, and the extension meets it — a rear wing designed and finished to match the home and the street, because in sought-after suburbs the addition that looks bolted-on costs you at sale.
The generous blocks take the full family wing comfortably.
The Class H junction
The clay means the footing junction is engineered so the new wing moves with the house — the detail that keeps quality additions crack-free.
That detail is a priced line, not a variation later.

How It Works
From First Call to Final Key
Free consultation at your Cecil Hills home. We inspect the existing structure, check Liverpool City 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.
⏱CDC (10–15 business days) or DA through Liverpool City 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 Cecil 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.
