A home extension in Busby costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Liverpool City Council approvals, and construction under one fixed-price contract.
Second-Storey & Rear Additions in Busby
Here is the question a home extension in Busby answers: would you rather spend $80K-plus on selling costs and stamp duty, or put that money into actual rooms? With the median at $700K to $900K and 1960s to 1980s houses on 500 to 650m² blocks, the gap between what your place is worth and what a bigger one costs, plus every dollar of friction in between, often funds a serious rear extension outright.
The housing era matters here. Some of that 60s to 80s stock is brick veneer that extends cleanly, while the lighter-framed homes need a structural look before anything bolts on. Either way, the block depth gives you room to add a family room and bedroom across the back without crowding the yard. Buildana works the Liverpool LGA constantly.
What I would check first on your Busby house: whether the frame is brick veneer or something lighter, and how much rear yard you have to work with. Those set the scope.

Rooms beat friction
With the median at $700K to $900K, selling and buying the next size up burns $80K-plus in stamp duty and agent fees before you gain a single room. A rear extension keeps that money in the building.
On 500 to 650m² blocks, Busby's 1960s to 1980s houses have the backyard depth to take it, so the gap that would go to friction funds the build instead.
Check the frame first
Some of that 60s to 80s stock is brick veneer that extends cleanly at ground level. The lighter-framed homes need a structural look before anything bolts on, which is a first-visit check, not an afterthought.
Either way the block depth lets you add a family room and bedroom across the back without crowding the yard. We work the Liverpool LGA every month, so the council side is known ground.

How It Works
From First Call to Final Key
On-site assessment of your 1960s–1980s-era home in Busby. We check structural condition, block dimensions (500–650m²), setback availability, and Liverpool City Council's DCP requirements.
⏱Designing an extension is half about the new space and half about how it joins the old one. Doorway position, ceiling height transition, floor level matching, light wells — the junction makes or breaks how the finished home feels.
⏱We lodge your extension approval — CDC for eligible designs or DA through Liverpool City Council. Full documentation including structural engineering for Class H soil, BASIX, and shadow diagrams.
⏱For ground-floor rear extensions you usually stay in the house during the build, with temporary weatherproofing at the junction wall until the new section is locked up. Second-storey additions need a 4–8 week relocation during the roof-off and frame-up phase.
⏱Final inspection, Occupation Certificate, 6-year structural warranty. Your Busby home now has the space your family needs.
⏱Quality Promise
Our Busby home extensions connect old-to-new cleanly. Matched brickwork, tied roofline, no awkward transitions.
