A home extension in Clovelly is usually a play for the water. This small beachside village between Coogee and Bronte runs Federation cottages and inter-war homes on 250 to 600m² blocks, many on a sandstone rise where a carefully set-back first floor claims a view of Clovelly Bay. In a $3M to $6.5M market, that view level is the most valuable room you can add.
Heritage Conservation Areas cover most of the older streets, so the frontage is examined closely while rear work generally moves more freely. Sandstone dominates the ground with substantial fall to the bay, so excavation is a test-dig conversation, and salt-grade fixings and coatings are standard this close to the water. Small blocks mean every square metre has to earn its place.
What I would check first on your Clovelly house: the heritage overlay on the frontage, whether a set-back upper level would catch the bay, and the sandstone fall. Those decide the design.
We build these fixed-price, licence HBL 487805C. Ask us what your street will allow before you design.
Buildana manages the complete home extension process in Clovelly — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

A play for the water
This pocket-sized beachside village between Coogee and Bronte runs Federation cottages and inter-war homes on 250 to 600m² blocks, many on a sandstone rise where a carefully set-back first floor picks up a view of Clovelly Bay.
In a $3M to $6.5M market, that view level is the highest-value room the house can gain.
Heritage, rock and salt

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Free consultation at your Clovelly home. We inspect the existing structure, check Randwick 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.
⏱The Clovelly construction phase. Fixed price, programmed, supervised. CDC (10–15 business days) or DA through Randwick 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 Clovelly.
⏱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.
