A home extension in Riverview almost always traces back to the college. Saint Ignatius' anchors the suburb and holds families in place for decades, so when the house gets tight the answer is to grow it rather than move out of reach of the school — conserved frontage kept, a generous wing built behind on 500 to 1,200m² blocks.
The heritage streets are checked before design, and the lots that face the river bushland carry BAL ratings, so those external materials are specified from the start. The pre-war fabric gets its lead and asbestos out under licence before the wing goes on.
At a $3.0M to $5.5M median, a wing designed for the long haul is the natural play — it carries the family through the school years and beyond, on a block with the room and the outlook to make it worthwhile.
We build these fixed-price, licence HBL 487805C. Get our extension scope, with heritage and BAL checked, before you commit.
Buildana manages the complete home extension process in Riverview — 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 college anchors everything
Riverview families stay for Saint Ignatius', so the wing is built to carry decades — conserved Federation frontage, generous modern living behind, on blocks with real room.
The elevated setting rewards a design that uses the outlook.
Heritage, BAL and fabric
The HCA streets are checked before design, and the river-facing bush lots get BAL-rated materials specified from the start.
The pre-war hazards run as licensed processes, every part of it priced into the job from the outset.

How It Works
From First Call to Final Key
Free consultation at your Riverview home. We inspect the existing structure, check Lane Cove 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 Lane Cove 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 Riverview.
⏱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.
