Local knowledge
Why Hornsby is several markets in one suburb.
Strava Group is a custom home builder working across Hornsby and the surrounding suburbs. Hornsby’s housing wraps around the town centre in rings: older homes near the station, mid-century brick further out, and bushland blocks on the edges where the terrain gets serious. Block to block, conditions change more here than almost anywhere we build.
That variety is the point. A Hornsby build can be a level block near the shops or a sloping bushland site with bushfire requirements, and the two need very different budgets. We tell you which one you have before you spend on design. Custom builds we take on in Hornsby include:
- Knockdown rebuilds on established blocks
- Single and two storey custom designs
- Sloping and tighter sites done properly
- Duplexes and dual occupancy where zoning allows
- Homes designed for light, outlook and the yard
- New homes on vacant or subdivided land
Not sure whether your Hornsby house wants a rebuild or a renovation? We build both, so the advice is honest. Sometimes the right answer is a home extension or a second storey, and we will tell you which one your block and budget actually want.
Hornsby is not one market. It is a town centre, a rail line and a bush edge, and the right build for your block depends on which one you are standing in.
A note from Stav
We built our name on extensions and second storeys. A custom home is different, and I treat it differently.
On every custom home you deal with me directly. I know the job in detail, I answer the phone, and I will still be standing behind the house years after handover. If that is the kind of builder you want on your new home, we should talk.

Start here
Tell us about your Hornsby block and your brief.
No sales pitch, no obligation. Here is exactly what happens when you enquire:
One at a time, takes about two minutes, so the first conversation is about your project rather than the basics.
Knockdown rebuilds
Knockdown rebuild in Hornsby.
Same street, same neighbours, same school catchment, new house. Here is what a Hornsby knockdown rebuild actually involves.
When rebuilding beats renovating
Where the existing structure is sound and suits the design, renovating or adding a storey can make better financial sense. Where the structure, layout or site constraints work against the brief, a knockdown rebuild may provide better value. We look at your house and tell you which one it actually wants.
Trees, bushland and bushfire ratings
Hornsby Shire Council requires consent before protected trees are pruned or removed, and Hornsby’s bushland edges can carry bushfire construction requirements that change materials, glazing and cost. We assess trees, terrain and bushfire exposure at feasibility, not at contract.
The approval pathway
Many Hornsby blocks suit a Complying Development Certificate through a registered certifier where the property and design meet the relevant standards. Sloping, bushfire affected or heritage affected sites may need a DA with Hornsby Shire Council. Demolition has its own approval. We identify the likely pathway early.
One contract, start to finish
Demolition, services disconnection and reconnection, and the new build run under one contract with one builder responsible, so nothing falls between contractors. You will need to move out from demolition to handover, and we raise that cost in the first conversation, not after you are committed.
A knockdown rebuild is still a custom home, and it gets the full Strava standard. Years of opening up older Sydney homes has shown us exactly how houses fail, and we build new ones to outlast those failures: footings engineered from your geotech report, frames built straight with proper bracing and clean load paths, waterproofing run as a documented hold point with a membrane system backed by a 15 year manufacturer warranty instead of the standard 7, and everything recorded before it is covered, including a 3D virtual model of the house captured before the gyprock goes on and handed to you at completion. What gets covered at construction still matters ten years later.
Honest numbers
How a Hornsby custom home is priced.
Custom homes are quoted per project, because the design, the site and the specification drive the cost. What we promise is how the number is built.
| Item | Typical range |
|---|---|
| Your build proposal | Itemised line by line |
| Inclusions and exclusions | Listed openly |
| Preliminaries | Shown separately |
| Allowances | Clearly identified |
Two identical floor plans can cost very different amounts on different Hornsby blocks: slope, soil, access, trees, demolition on a knockdown rebuild, and the specification you choose all move the number. Anyone who quotes a custom home off a phone call is guessing, and the guess always grows.
So we do it the slow, honest way: we walk your block, we talk through the brief and the budget, and the proposal you receive is itemised line by line: what is included, what is excluded, and what the preliminaries are. No buried allowances. Where an item cannot reasonably be finalised before contract, it is identified clearly rather than hidden inside the total.
We use a fixed price (lump sum) building contract, agreed before signing.
