Extending out, not up
Opening a Cabarita home to the garden and the water.
Strava Group builds home extensions in Cabarita: rear extensions, side additions and whole-of-back transformations that open the house to the yard. Cabarita is a small peninsula suburb where the park, the ferry wharf and the water set the tone, with Federation and interwar homes on the older streets and substantial post-war brick on the rest. The land is valuable, the streets are quiet, and the brief is nearly always the rear: a bigger kitchen and living that opens to the garden, and on the right blocks, toward the water.
In Cabarita 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.
Local knowledge
What we know about extending in Cabarita.
Every suburb builds a little differently. This is what matters when you are extending a Cabarita home.
Council
Cabarita sits in the City of Canada Bay Council area under the Canada Bay Local Environmental Plan 2013 and the Canada Bay Development Control Plan. Foreshore controls apply on the blocks near the water and some streets carry heritage controls, where extensions go through a Development Application. Elsewhere 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 City of Canada Bay Council and on the NSW Planning Portal.
Housing stock
Federation and interwar homes on the older streets toward the park and the wharf, a solid stock of substantial post-war full brick and brick veneer houses, and newer homes along the foreshore. Many of the older houses carry a lean-to or enclosed verandah added decades ago that was never built to last. Those earlier additions usually come off and are replaced with something engineered.
Structure
Older Cabarita homes are double brick on timber floors with hardwood framing and terracotta roofs, and the post-war stock is often full brick on a slab. Cutting a new opening into a double brick rear wall needs an engineered lintel and careful propping, and the new floor has to land exactly on the existing level. Brick veneer homes extend more simply once the load path is engineered.
Yard and block
Blocks are typically 450 to 700 square metres, with the streets toward the water often sloping toward the bay. Side access varies, and where it is tight materials come through the house and the programme changes. A full width rear extension with a usable garden kept beyond it is the usual move, and on the sloping foreshore blocks the extension often steps down the site.
Services and ground
Cabarita sits on shale derived clay over Hawkesbury sandstone, with the rock closer to the surface toward the foreshore. Footing design varies across the suburb, so the engineering is done for your site, and new footings are detailed against the existing ones so the extension does not settle away from a house whose original footings were never engineered. Services along the rear boundary are located before design starts.
Value
Cabarita is one of the most valuable pockets of Canada Bay, with the park, the ferry and the water keeping demand strong on a small number of streets. Buyers pay for a character or quality post-war house with a properly built modern rear, and an extension that delivers that is one of the safest improvements you can make here, and far cheaper than buying the bigger house down the street.
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 Cabarita 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 on Cabarita sandstone the challenge is usually matching new rock-founded footings to old ones that 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 Cabarita.
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 Cabarita the value of the land tends to justify extensions in the middle and upper part of the band, with foreshore sites, sandstone and older double brick structure adding engineering work. How much of the existing structure has to change is usually the largest single factor, followed by wet areas, access and rock.
Every project is quoted properly after a site inspection. These ranges are here so you can decide whether it is worth a conversation.
