Second Storey Additions · North Ryde
Add bedrooms, bathrooms & living space, without moving.
Fixed price second storey additions for North Ryde homeowners, from $274,000. Built to our Above Standard Carpentry Specification, with a solid Hebel PowerFloor included as standard on early projects.
Hebel PowerFloor included free on early North Ryde packages. A solid, quieter floor, normally an upgrade.
Space without moving
More room, without leaving North Ryde.
You love your North Ryde 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 North Ryde, with Macquarie Park and the Metro up the road and the national park over the back fence, 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 North Ryde homes do not fit them. Wider footprints, a second 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.
- 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 North Ryde home. Package price covers the new upper floor works. Design, engineering and council approvals are quoted separately as preliminaries, at roughly $30,000.
The Strava difference
A solid, quieter upstairs.
Most second storey additions sit on 19mm lightweight particleboard. While it does the job, it can feel hollow and bouncy underfoot. As a result, footsteps carry straight down to the rooms below.
For early Strava Group projects in North Ryde we include Hebel PowerFloor as standard. It is a 75mm autoclaved aerated concrete panel, almost four times thicker than standard flooring. Laid over your joists, it creates a solid, concrete style floor.
- 75mmAlmost 4 times thicker than standard 19mm particleboard, so it feels solid underfoot with no bounce or flex.
- 0Squeak free. The thick AAC panel does not creak the way timber based flooring can over time.
- ↓Helps reduce noise transfer between levels for a quieter upstairs, especially with the right ceiling system.
- ✦Non combustible AAC, with thermal insulation and moisture resistance built in.
Local knowledge
Building a second storey in North Ryde.
North Ryde is sixties brick on generous blocks, ringed by Lane Cove National Park and pulled along by Macquarie Park. Here is what shapes a project locally.
City of Ryde
North Ryde sits within the City of Ryde. For a typical house block the controls are workable, and a well designed second storey usually fits inside them.
Mostly CDC territory
North Ryde has little heritage overlay, so the fast Complying Development pathway is available on most blocks and approval can run in weeks rather than months. We confirm your block qualifies before quoting.
Sixties brick on good bones
North Ryde is classic fifties and sixties brick veneer and clad cottages, built solid on generous blocks. Post war footings are usually a better starting point than Federation era piers, but the engineer still confirms what is under your home before anything is designed.
Generous and workable
North Ryde blocks are among the most workable in the district: a decent size, driveway access on most, room for a crane. Established gardens and street trees are what the plan works around, not the frontage.
Bushland edges and clay
Streets backing onto Lane Cove National Park can carry bushfire planning provisions, and the clay soils through this district move with the weather. Both are checked before we quote, because both affect the footings and the approval more than the design.
Match the street you are on
On a conservation street, keeping the new level sympathetic to the Federation roofline is what gets the DA through. On a post war street, two storeys already sit comfortably. Same suburb, two different design briefs, and we start by reading the street.
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. A post war North Ryde home on brick piers and a 1965 one on strip footings get to a second storey differently. Both can carry one; the engineer confirms what is under yours 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
City of Parramatta 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
Street trees, established gardens and the odd steep fall toward the creeks are the usual access questions in North Ryde. 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.
Clear scope
What is included, and what is not.
Being upfront about both is exactly how we keep your fixed price genuinely fixed.

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.
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 North Ryde the block usually gives you a real choice, and the age of the house often casts the deciding vote.
Go up
Go up if the yard matters to you. North Ryde blocks are generous, and a second storey keeps every metre of it while adding the bedrooms upstairs.
It costs more per square metre than extending out, but it leaves the garden and the side access intact, and two storey homes already sit comfortably in most North Ryde streets, and the conservation streets have their own rules we design for.
Extend out
Extending out is a genuine option in North Ryde, unlike the inner west. Blocks are deep enough that many homes can give up yard and still keep plenty.
Ground floor work is cheaper per square metre, you can often stay living there, and it avoids the structural question entirely. A rear home extension in North Ryde can be the better value answer.
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.
Plan · Manage · Build
Your North Ryde second storey, step by step.
Our proven building process is designed to customise your project, avoid cost traps and deliver your vision with minimum disruption.
Your Initial Assessment
First, we review your enquiry, site, timeframe and budget. Then we contact you within 24 to 48 business hours to arrange a consultation.
Consultation & Build Cost Estimate
An experienced builder discusses your project and site, then prepares a detailed build cost estimate.
Preliminary Agreement
This formalises your engagement, secures your spot in our schedule and starts coordination with consultants and authorities.
Plans & Design
Next, we coordinate design and documentation. As a result, you get plans that suit your brief, site and budget, with optional 3D modelling.
Submission to Council
After that, we prepare and lodge your DA and CC, or a CDC with the City of Parramatta. Approval typically takes around 4 to 8 weeks.
Final Cost & Contract
Once approved, we confirm the final build cost and issue your HIA Fixed Price Building Contract. Importantly, you review it in full before signing.
Pre-Start Selections
Together, we finalise your fixtures, fittings and finishes with suppliers, so everything is confirmed before work begins.
Start of Construction
Your project manager meets you on site to confirm documentation, expectations and communication before works commence.
Construction
Your project manager oversees the build, coordinates trades and manages quality, keeping disruption to a minimum.
Practical Completion
A final inspection, then warranties and compliance documents are provided. We stay available after handover.
