School catchments keep Padstow families anchored, and a home extension is how they stay without squeezing. The suburb's 1940s to 1970s homes sit on 500 to 700m² blocks with the kind of backyard depth that makes a rear extension straightforward: extra bedroom, second living zone, a kitchen that finally fits the household. At a $1.1M to $1.4M median, that build costs a fraction of upsizing within the same catchment.
A word on the older end of the stock: 1940s to 1950s construction varies wildly under the cladding, and what carries a renovation happily may need reinforcement before it borders a new structure. We open up and check before we quote structure, not after. With the station in the suburb and Padstow Park up the road, the case for staying put is already made.
What I would check first on your Padstow house: the condition of the older framing under the cladding, and how much the rear yard can take. Those set the scope.
We build these fixed-price, licence HBL 487805C. Let us see what your block supports.

Stay anchored, add the space
School catchments keep Padstow families anchored, and a rear extension lets them stay without squeezing. The 1940s to 1970s homes sit on 500 to 700m² blocks with real backyard depth.
An extra bedroom, second living zone and a kitchen that fits the household is the standard build, and at a $1.1M to $1.4M median it costs a fraction of upsizing in the same catchment.

How It Works
From First Call to Final Key
The first job on an extension is finding out what you're extending onto. Padstow homes from the 1940s–1970s were built to different standards — we open walls, check footings, verify load paths. The existing house has to carry the new work.
⏱Design follows the existing roof. A bad extension looks like a bolt-on; a good one reads as original. Matched brickwork or contrasting render (whichever the architecture calls for), tied-in roofline, continuous flooring where it should be continuous.
⏱Construction happens while you live in the house. That means weatherproofing every night, staging the works so kitchens and bathrooms don't disappear on the same week, and keeping the site clean of debris that doesn't belong in a family home.
⏱Finish is seamless. Paint match, floor match, roofline match, brick match where possible. The only way to tell the extension is new is the date on the plans.
