Extending out, not up
More room at the back of a Burwood home.
Strava Group builds home extensions in Burwood: rear extensions, side returns and whole-of-back transformations that open the house to the yard. Burwood mixes grand Federation homes around the Appian Way and Burwood Park with interwar bungalows and 1960s brick closer to the station. On most of them the front half is worth keeping and the back half is where the extension earns its money: a bigger kitchen, open plan living and a proper connection to the yard.
In Burwood we regularly deliver:
- Rear extensions and additions
- Side extensions on wider blocks
- Open plan kitchen, dining and living
- Alfresco and indoor-outdoor connections
- New master suites and family rooms
- Laundries, mudrooms and storage done properly
- Structural openings between old and new
- Exterior upgrades to tie old and new together
Thinking about going up instead? That is a different build with different engineering, and we do that too: see second storey additions in Burwood.
Local knowledge
What we know about extending in Burwood.
Every suburb builds a little differently. This is what matters when you are extending a Burwood home.
Council
Burwood is its own local government area under the Burwood Local Environmental Plan 2012 and the Burwood Development Control Plan. Parts of the suburb, including the Appian Way and several streets around Burwood Park, sit inside heritage conservation areas where extensions go through a Development Application. Outside those areas many detached homes can use Complying Development through a private certifier. We confirm the pathway for your property before quoting. Current planning controls are published by Burwood Council and on the NSW Planning Portal.
Housing stock
Federation and interwar houses on the better streets, some of them substantial, with a solid stock of 1950s and 60s brick homes and semis toward the station and Croydon. Many of the older houses carry a lean-to or sunroom addition from the 1970s or 80s that was never built to last. Those earlier additions usually come off and are replaced with something engineered.
Structure
Older Burwood homes are double brick with timber floors on brick piers, hardwood roof framing and terracotta or slate tiles. Cutting new openings into a double brick rear wall needs engineered lintels and careful propping, and the new floor has to land exactly on the existing floor level. Semis share a party wall, which changes both the engineering and the neighbour approach, so those are always custom projects.
Yard and block
Blocks range widely, from 400 square metres on the tighter streets to well over 800 on the Appian Way and around the park. Side access is the first thing we check, because without it materials and spoil come through the house and the programme changes. A full width rear extension with the yard kept beyond it is the usual move.
Services and ground
Burwood sits on shale derived clay soils that move with moisture, and the footings under a 1910s house were never designed to modern standards. New footings are engineered for the site and detailed against the old ones so the extension does not settle away from the house. Sewer and stormwater lines often run along the rear boundary and need to be located before design starts.
Value
Burwood is one of the inner west suburbs where a well extended character home holds its value best: the station, Westfield and the school catchments keep demand steady. Buyers pay for the Federation front with a properly built modern rear, and an extension that delivers that is one of the safest improvements in the suburb.
The Strava standard
How we build differently.
An extension lives or dies at the junction between old and new. We build for longevity, and on every Burwood extension we run:
Every new-to-existing junction properly detailed
This is where most extensions crack, leak and part company with the house. It is almost always a detailing shortcut, not settlement. Ours get a proper structural tie, flashing and movement detail.
The existing structure gets rectified, not covered
Where the extension meets the house, we screw off and re-brace the adjoining structure, tying new and old together so the whole building moves as one and future cracking is designed out, not painted over.
Footings matched to the ground, not the minimum
New footings are engineered for your soil and detailed against the existing ones, because differential movement between old and new slabs is the classic extension failure, and it matters more on a century-old house whose original footings were never engineered.
Furring channels for a dead flat finish
Where new ceilings and walls run through to existing rooms, furring channels give one level plane across both, so you cannot see where the house ends and the extension begins.
Waterproofing is a documented hold point
New wet areas are inspected and photographed before a single tile goes on, to AS 3740, and new roof-to-old-roof junctions get the same treatment.
Everything photographed before it is covered
You receive the record at handover, so in ten years you know exactly what is behind your walls and under your floor.
Before starting Strava Group, I spent seven years on the tools as a carpenter and five years running sites. The failures I kept seeing in extensions were always at the join: cracked cornices along the old wall line, roofs that leaked where new met old, floors that stepped as slabs settled differently. None of it was illegal. All of it was avoidable. None of this shows up in a finished-room photo. All of it shows up in year seven.
Honest numbers
What a house extension actually costs in Burwood.
Most builders will not put numbers on a website. We will, because the alternative is wasting your time and ours across three meetings before anyone mentions a figure.
Preliminaries are the costs that exist before a single wall moves: site fencing, temporary services, waste removal, insurances, engineering and supervision. They are real, they are unavoidable, and a quote that does not show them separately has either buried them or forgotten them.
In Burwood the smaller blocks on the tighter streets keep projects in the lower and middle part of the band, while the larger heritage homes around the park can run to the top of it. How much of the existing structure has to change is usually the largest single factor, followed by wet areas, side access and the work involved in taking off an earlier lean-to.
Every project is quoted properly after a site inspection. These ranges are here so you can decide whether it is worth a conversation.
