Second-Storey & Rear Additions in Bexley North
A home extension in Bexley North is a staying decision built around the station. The inter-war homes on 450 to 700m² blocks sit within a walk of the platform, and that walk is the asset — so the wing adds the bedrooms and living the family has outgrown while the commute stays exactly as easy.
The era of the house steers how far the plan can push, the older fabric gets licensed handling where we open it, and the wing is drawn to sit inside the established street rather than shout over it.
At a $1.6M to $2.4M median the maths of staying wins cleanly — the upsizing friction alone funds most of the addition.
We build these fixed-price, licence HBL 487805C. Ask us to measure what your block can hold.
Buildana manages the complete home extension process in Bexley North — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Keep the walk to the platform
The short walk to Bexley North station is what makes the pocket work, and extending banks it — the wing brings the extra bedrooms and living while the commute stays a stroll.
Reading the era keeps the budget aimed where it counts.
Fabric handled as we go
The inter-war and post-war fabric gets licensed handling wherever the work opens things up.
That removal is costed in the quote from the start, not discovered halfway through.

How It Works
From First Call to Final Key
Walk through your Bexley North home with our designer and structural engineer. We measure, photograph, and check the bones — footings, frame condition, roof structure.
⏱Our designer works with your existing home's layout — connecting new living areas to existing rooms, matching materials and roof pitch, and maximising natural light. You approve floor plans and 3D renders before we proceed.
⏱Most rear extensions in Bexley North qualify for CDC — cleaner, faster, no neighbour notification. Second-storey additions typically need DA through Bayside Council because of overshadowing and privacy assessments.
⏱Extension built from new footings to completion — connecting structurally to your existing home. Class M soil design managed.
⏱Walk through the completed extension, confirm finishes, collect your OC. Six-year structural warranty covers all new work including the junction with your existing home.
