Space without moving
More room, without leaving Beecroft.
You love your Beecroft street, your neighbours, the school run. What you do not love is running out of space. Moving means stamp duty, agent fees and starting over somewhere that may never feel like home.
On a million dollar purchase, stamp duty alone runs to roughly $40,000 before you have paid an agent, a conveyancer or a removalist. In a suburb like Beecroft, with the station in the village and the schools families move here for, that maths rarely favours moving.
A second storey addition lets you stay exactly where you are and build the space you need. Extra bedrooms, a second bathroom, a private master retreat or an upstairs living zone, without giving up a metre of backyard.

Not a package job?
Custom second storey additions.
The three packages cover the shapes we build most often. Plenty of Beecroft homes do not fit them. Wider footprints, a third bathroom upstairs, a full ground floor reconfiguration underneath, or a split level that has to be worked with rather than against.
We build those too, priced against your plans rather than squeezed into a package. Same fixed price contract, same standards, same specification. Custom builds generally run $270,000 to $400,000 depending on size and what we find underneath.
Custom builds
Priced to your plans
- Any size or configuration
- Ground floor works included in scope
- Heritage and character homes
- Structural upgrades where needed
Every plan is drawn to suit your Beecroft home. Package price covers the new upper floor works. Design, engineering and council approvals, plus site set-up, are quoted separately as preliminaries, at roughly $30,000.
The Strava difference
A solid, quieter upstairs.
Most second storey additions leave the cavity between the new floor joists empty. While the floor does the job, that hollow space lets sound travel. As a result, footsteps carry straight down to the rooms below.
For early Strava Group projects in Beecroft we include acoustic insulation in the subfloor free. Insulation batts fill the space between the new floor joists, with yellow tongue particleboard flooring laid over the top. It is a simple step that makes for a quieter upstairs.
Free

Diagram is illustrative. Acoustic ratings apply to the complete floor and ceiling system, not the batts alone, and depend on the ceiling, insulation and joist design. Subfloor acoustic insulation is included where suitable, subject to engineering, access and final scope.
Local knowledge
Building a second storey in Beecroft.
Beecroft is one of the prettiest suburbs in the district, and the planning rules exist to keep it that way. Here is what shapes a project locally.
Council
Hornsby Shire Council
Beecroft sits within Hornsby Shire Council. The controls here lean protective, because the leafy garden character of the suburb is exactly what the planning scheme is built to keep.
Heritage
Much of Beecroft is a conservation area
Large parts of Beecroft and neighbouring Cheltenham sit within the Beecroft Cheltenham Heritage Conservation Area. For those homes the fast Complying Development pathway is off the table and a full Development Application is required. That changes the timeline, not the possibility, and some of the best additions in the district are on conservation streets.
Housing
Federation homes and garden bungalows
Beecroft is Federation and interwar stock at its best: brick and timber homes with real rooflines, on footings built for one storey. The roof structure and the footings both get checked before anything is designed, because both usually need work to carry a new level.
Trees
The canopy is protected
Beecroft’s tree canopy is part of the conservation character, and Hornsby Shire protects it accordingly. Significant trees near the build zone shape the design and the crane plan, and they are far cheaper to design around than to fight.
Blocks
Big, established, workable
Blocks here are generous, often 700 square metres and up, with driveways and room to work. Access is rarely the problem. The established gardens are what the crane plan works around.
Streetscape
The street decides the roof
In a conservation area, council assesses an addition against the street. Keeping the new level sympathetic to the existing roofline, and often behind the ridge as seen from the street, is what gets a Beecroft DA approved. We design for that from the first sketch.
We confirm which approval pathway your Beecroft property falls under before we quote, so you know the timeline before you commit to a design.
Before anything is designed
Can your house actually take a second storey?
This is the first question, and it usually gets skipped in favour of talking about floor plans. It is worth answering properly, because for roughly one house in six the answer is no, or not without spending money you would rather put into the addition itself.
What is under the house
Your house was built to hold up one storey. A second floor roughly doubles what the foundations carry. Federation era Beecroft homes commonly sit on brick piers or shallow strip footings built for one storey. Honest construction for its time, and the first thing the engineer confirms before a design is drawn. That is a real cost, and you want to know about it before you fall in love with a floor plan.
What the walls are made of
A double brick house, a brick veneer house and a timber framed house each handle a new floor differently. The question is whether the weight can travel down through the walls you already have, or whether new supports need to appear somewhere you would rather they did not.
What the timber has been through
Framing that looked fine when you bought the place can be quietly damaged in ways that only matter once you ask it to hold a floor up. We look before we quote, not after.
What your council allows
Hornsby Shire Council sets a height limit and protects your neighbours’ winter sunlight. Between them, those two rules often decide your ceiling heights and your roof shape before anyone draws anything.
Whether we can get a crane in
Established trees and gardens are the usual access questions in Beecroft, and protected trees can shape the crane plan. We flag both at the first visit. Better to know at the start than in week three.
How we find out
An engineer checks the first three. We organise that before we give you a fixed price, because a price without it is a guess.
If your house cannot take a second storey without spending more than it is worth, we will tell you. Building out the back is usually the better answer in that case, and we build home extensions in Beecroft too.
Clear scope
What is included, and what is not.
Being upfront about both is exactly how we keep your fixed price genuinely fixed.
Included as standard
In the new upper floor package area.
Quoted separately if needed
Every existing Beecroft home is different, so these are assessed per property.
Want the full detail?
The complete inclusions and exclusions, right down to hardware, fixtures, fittings, finishes and specifications, are provided in detail when you enquire, and confirmed in your contract.
How the fixed price works
Our fixed price packages apply to the standard new upper floor works listed above. If your property needs structural steel, footing upgrades, extra bracing, service upgrades, defect repairs or downstairs renovation works, those items are assessed and quoted separately, clearly, before you commit. Where something genuinely cannot be priced until the roof comes off, it is listed as a provisional sum with a stated allowance rather than hidden inside the total.
The first decision
Up or out?
Most people arrive having already decided. In Beecroft the block gives you a real choice, and the garden usually casts the deciding vote.
If the existing house needs work regardless, a full renovation staged alongside the addition costs less than doing them five years apart, because you pay the preliminaries once and open the walls once.
