Sefton's housing is honest post-war stock. 1940s to 1970s homes on 500 to 700m² blocks near the station, and the first question for any renovation here is what the walls are made of. Fibro from that era means asbestos-cement sheeting, and we treat it the only defensible way. Tested before contract, removed by licensed contractors, priced in writing before demolition starts. The brick homes from the same decades skip that step and go straight to the real work of opening up plans built for 1955.
Budget honesty matters at a $950K to $1.15M median. The renovation that pays in Sefton is the one that delivers a modern kitchen, two fresh bathrooms and a connected living-dining space without chasing finishes the street cannot return. Rail in the suburb keeps family demand steady, and renovated post-war homes near stations are what that demand buys.
What I would check first on a Sefton home: whether it is fibro or brick, where any asbestos is, and how far the 1955 plan can open. Those set the scope.

What are the walls made of?
The first question on any Sefton renovation is the wall material. Fibro from the 1940s to 1970s means asbestos-cement sheeting, which we test before contract, remove under licence, and price in writing before demolition starts. The brick homes of the same decades skip that step.
Once the wall question is settled, the real work is opening up plans built for 1955 into the connected living families want now.
Spend what the street returns

How It Works
From First Call to Final Key
On-site meeting to walk through your Sefton home room by room. We identify what needs to change, what can stay, and where the budget delivers the most impact. Written scope and cost estimate within a week.
⏱Design includes selections for everything you'll touch: tapware, tiles, benchtops, splashbacks, joinery handles, paint colours, lighting, flooring. We lock these at design stage with cost-confirmed inclusions, not provisional sums that creep up during construction.
⏱If your renovation involves structural work, we lodge DA or CDC with Canterbury-Bankstown Council. Most kitchen and bathroom renovations don't require approval. Buildana advises on what needs lodgement and what doesn't.
⏱Trade sequencing is the difference between a 6-week renovation and a 12-week one. Demo, structural, plumbing rough-in, electrical rough-in, plaster, waterproofing, tiling, joinery install, fit-off, paint — each trade in and out cleanly, no waiting on the next sub.
⏱Final inspection, Occupation Certificate (if required), 6-year structural warranty on any structural work, and maintenance guide. Your Sefton home, transformed.
