A home extension in Little Bay costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Randwick City Council approvals, and construction under one fixed-price contract.
Little Bay Home Extensions & Additions
A home extension in Little Bay gets an honest answer more often than a sales pitch. The stock is 2000s-onward master-planned coastal housing, and most of it is simply too young to need a major addition — so the genuine work here is targeted rather than a wing, and I will tell you plainly where the home needs nothing yet.
Where work does make sense, the estate's design guidelines shape what the external part can be, and the cliff-top exposure dictates the materials — everything outside is salt-grade, because the air out here destroys anything less. The cliff fall is engineered where the structure changes.
At a $2M to $4M median, work done within the plan holds the coastal premium — the coherent look and the setting are what you paid for, so any addition is built to protect both.
We build these fixed-price, licence HBL 487805C. Tell me the brief and I will give you the honest read.
Buildana manages the complete home extension process in Little Bay — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Young stock, honest reads
Little Bay's homes rarely need major additions yet, and I say so — the genuine work is targeted: outdoor rooms toward the coast and golf course, upgrades where builder-grade finishes wore early.
Everything external is in salt-grade materials, because the cliff-top exposure mandates it.
Clean fabric, engineered edges
The clean fabric keeps whatever proceeds simple.
The cliff fall is engineered where the structure changes, and all of it is priced into the job from the outset.

How It Works
From First Call to Final Key
Extension feasibility comes down to two things: what the existing structure can carry, and what Randwick City Council will let you build. We assess both at the consultation — no point designing for a second storey if the slab can't take the load.
⏱Extension designed to integrate with your existing Little Bay home — matching roof lines, materials, and flow between old and new sections. Floor plans, elevations, and 3D renders.
⏱All approval documentation prepared: structural drawings, BASIX, shadow analysis, stormwater, and statement of environmental effects (if DA). Lodged and managed through to Construction Certificate.
⏱Extension construction takes 3–6 months on average. Footings excavated and poured to match existing depth on Class M soil, frame stand, roof tie-in (most weather-critical phase), lock-up, then internal fit-out at the same standard as the existing house.
⏱Defect-free inspection, OC issued, 6-year warranty on all new work. Junction between old and new sections waterproofed and warranted.
⏱Quality Promise
We extend Little Bay homes with a structural engineer on every job. Second storey, rear addition, multi-room — engineered and priced upfront.
