Home extensions in Beecroft, done properly.

Extending out, not up
Extending a Beecroft home without losing what makes it Beecroft.
Strava Group builds home extensions in Beecroft: rear additions, side extensions and whole-of-back transformations that open the house to the garden. Beecroft is one of the few suburbs where the extension has to answer to the street as well as to you. Most of the suburb sits inside the Beecroft Cheltenham Heritage Conservation Area, the blocks are large and heavily treed, and the original houses are worth keeping. A rear extension that sits behind the house and opens it to the garden is the natural fit.
In Beecroft 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 Beecroft.
Local knowledge
What we know about extending in Beecroft.
Every suburb builds a little differently. This is what matters when you are extending a Beecroft home.
Council
Beecroft is in the Hornsby Shire Council area under the Hornsby Local Environmental Plan 2013, and most of the suburb sits inside the Beecroft Cheltenham Heritage Conservation Area. That removes the Complying Development pathway, so extensions go through a Development Application with a heritage assessment. Rear extensions that sit behind the main roofline and keep the street presentation are well supported. We confirm the pathway for your property before quoting. Current planning controls are published by Hornsby Shire Council and on the NSW Planning Portal.
Housing stock
Federation and interwar homes on generous blocks, a good stock of 1950s and 60s brick and weatherboard houses, and some later architect designed homes set among the trees. Many of the older houses have been extended once before, and the quality of that earlier work varies. A proper rear extension often replaces it rather than adding to it.
Structure
The older Beecroft homes are double brick or timber framed with weatherboard cladding on brick piers, usually with hardwood floors and framed roofs. Cutting a new opening into an old rear wall needs an engineered lintel and careful propping, and matching the new floor to the existing suspended timber floor is a detail that has to be right. Weatherboard homes extend well in timber, and the junction is where the flashing has to be done properly.
Yard and block
Blocks in Beecroft are typically 800 to 1,200 square metres and often larger, many of them sloping and most of them 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, which is the point of living here.
Services and ground
Beecroft sits on shale derived clay soils with sandstone close to the surface in places, so footing design varies across the suburb and sometimes across a single block. New footings are engineered for the site and detailed against the existing ones so the extension does not settle away from a 100 year old house. Old services and absorption trenches on larger blocks need to be located before we design.
Value
Beecroft is a tightly held suburb where the conservation area, the trees and the school catchments protect value. Buyers here pay for character houses that have been extended properly at the rear, and the worst thing you can do is a cheap addition that fights the original. A considered rear 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 Beecroft 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 Beecroft.
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 Beecroft the larger blocks allow substantial extensions, but the heritage process, protected trees and sloping sites add design and engineering work that pushes projects toward the middle and upper part of the band. How much of the existing structure has to change is usually the largest single factor, followed by wet areas, site access around trees 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.
