Second-Storey & Rear Additions in Maroubra

The ocean is one storey up from most of Maroubra, and that fact drives half the home extension work in the suburb. Federation and inter-war homes on the 350 to 700m² blocks east of Anzac Parade sit on a sandstone rise where a first-floor addition often buys a genuine water view. In a $2.2M to $4.5M market, a view level is the most valuable room you can build.

Coastal-facing builds here get salt-grade specifications as standard: stainless fixings, marine-grade coatings, sealed detailing, because ordinary materials corrode fast this close to the beach. Heritage Conservation Area pockets around the village core scrutinise front elevations while leaving rear extensions largely alone, which suits the inter-war double brick that carries additions so well.

What I would check first on your Maroubra house: whether a first floor would actually claim a water view, the heritage overlay on the front, and the salt-grade spec the exposure demands. Those decide the design.

We build these fixed-price, licence HBL 487805C. Scope the view from your roofline with us before you decide.

Buildana manages the complete home extension process in Maroubra — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

The view is one storey up

The Federation and inter-war homes on the 350 to 700m² blocks east of Anzac Parade sit on a sandstone rise, where a first-floor addition often buys a genuine water view.

In a $2.2M to $4.5M market, that view level is the most valuable room you can build, which is why so much local work goes up.

Salt-grade as standard

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 Maroubra 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. Maintenance guide covers care of new and existing areas.
