Home Extension Builder in Manly
Manly makes you earn every square metre. Blocks run just 250 to 700m², Heritage Conservation Areas stretch across most of the older streets, and council reads street-facing changes to Federation and inter-war homes very closely. So a home extension here is usually a rear project, a carefully set-back first floor, or both. Done well, it is the difference between a charming small house and a family home worth $3.5M-plus.
The rewards justify the rules. A recessed second storey that catches ocean or harbour glimpses adds serious value in this market, and rear extensions opening onto the yard suit the beach-house stock naturally. Sandstone excavation at $50K to $150K-plus means we test-dig before pricing groundwork, and salt-grade materials are standard this close to both waterfronts.
What I would check first on your Manly block: the heritage overlay on the frontage, the sandstone under any dig, and whether a set-back upper level would claim a water glimpse. Those shape the whole design.
We build these fixed-price, licence HBL 487805C. Bring us your address and we will tell you what Manly will let you build.
Buildana manages the complete home extension process in Manly — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

How It Works
From First Call to Final Key
Free consultation at your Manly home. We inspect the existing structure, check Northern Beaches 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 Northern Beaches 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 Manly.
⏱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.
