Home extensions in Epping, done properly.
Rear and side house extensions for Epping homes by a licensed extension builder. Most extensions run $70,000 to $300,000 depending on size and how much of the existing house has to change, itemised quote, honest programme, one builder from concept to handover.

Extending out, not up
Extending an Epping home on a generous block.
Strava Group builds home extensions in Epping: rear additions, side extensions and whole-of-back transformations that open the house to the garden. Epping is a suburb of two halves: the town centre has gone up, but the streets behind it are still Federation, interwar and mid-century homes on large, leafy blocks, with several heritage conservation areas protecting the character. Those blocks are prime extension country, and the original houses are usually worth keeping at the front.
In Epping 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 Epping.
Local knowledge
What we know about extending in Epping.
Every suburb builds a little differently. This is what matters when you are extending a Epping home.
Council
Epping sits mostly in the City of Parramatta Council area under the Parramatta Local Environmental Plan 2023, with the northern edge in Hornsby Shire. Several Epping precincts, including streets around Essex Street and Rosebank Avenue, sit inside heritage conservation areas where extensions go through a Development Application. Outside those areas most 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 Parramatta Council and on the NSW Planning Portal.
Housing stock
Federation and interwar homes on the older streets, a broad stock of 1950s and 60s brick and weatherboard houses, and later two storey homes on the larger blocks. Many of the older houses have been extended once before, often with a fibro sunroom or lean-to that was never built to last. Those earlier additions usually come off and are replaced with something engineered.
Structure
Older Epping homes are double brick or weatherboard on timber floors with hardwood framing and terracotta roofs, and the mid-century stock is brick veneer on a timber frame. Cutting a new opening into a double brick rear wall needs an engineered lintel and careful propping, and the new floor has to meet the existing suspended floor exactly. Brick veneer extends more simply once the load path is engineered.
Yard and block
Blocks in Epping are typically 700 to 1,000 square metres and often larger on the older streets, many of them sloping and treed. The trees are protected under council controls and usually shape where the extension can go. The size of the block means a substantial rear extension is possible while keeping a real garden.
Services and ground
Epping sits on shale derived clay soils that move with moisture, with sandstone near the creek lines toward the Lane Cove valley. New footings are engineered for the site and detailed against the existing ones so the extension does not settle away from the house. Old services and absorption trenches on the larger blocks are located before we design.
Value
Epping is one of the best connected suburbs in northern Sydney, with rail and Metro, the town centre and strong school catchments holding demand. Buyers here pay for character houses on big blocks that have been extended properly at the rear, and a considered extension that keeps the front intact 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 Epping 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 an older house whose original footings were never engineered to modern standards.
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 Epping.
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 Epping the larger blocks allow substantial extensions, which tends to put projects in the middle and upper part of the band, with heritage controls on some streets, protected trees and sloping sites adding design and engineering work. How much of the existing structure has to change is usually the largest single factor, followed by wet areas and how far footings have to go to find good ground.
Every project is quoted properly after a site inspection. These ranges are here so you can decide whether it is worth a conversation.
