Limited time offer

Hebel PowerFloor included free on early Parramatta packages. A solid, quieter floor, normally an upgrade.

Space without moving

More room, without leaving Parramatta.

You love your Parramatta 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 Parramatta, with the CBD, the Metro and the river at your door, 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.

Strava Group builds second storey additions across Parramatta and the surrounding suburbs. About us.

Same land. Same street. Same address. A whole new upstairs.

Not a package job?

Custom second storey additions.

The three packages cover the shapes we build most often. Plenty of Parramatta 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.

Custom builds

  • 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 Parramatta 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 Parramatta 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 Parramatta.

Parramatta is a CBD ringed by established house streets, and the two could not be more different to build in. The houses are what we build on, and here is what shapes a project locally.

Council

City of Parramatta

Parramatta sits within the City of Parramatta, and the council runs two planning worlds side by side: high rise in the CBD, protective controls through the house streets. For a typical house block a well designed second storey usually fits inside the controls, though the conservation streets play by different rules.

Heritage

Some of the oldest streets in the country

Parramatta holds some of the oldest European buildings in Australia, and the conservation areas around them are managed accordingly. Inside them, the fast Complying Development pathway is off the table and a Development Application applies. Outside them, CDC is usually available. Which side of the line your block sits on is the first thing we check.

Housing

Federation fronts, post war backs

Parramatta runs the full range: Federation and interwar homes through the older streets, post war brick veneer and fibro through the rest. Each carries a second storey differently, and the footings under a 1915 house and a 1965 house are not the same conversation. The engineer confirms which you have before anything is designed.

Blocks

Established and workable

Parramatta house blocks are a decent size with driveway access on most. Established gardens and street trees are what the crane plan works around, not the frontage.

Terrain

The river, the creeks and clay

Parts of Parramatta fall toward the river and its creeks, some streets carry flood planning controls, and the clay soils through this district move with the weather. All three affect the footings and the approval more than the design, and all three are exactly what gets checked before we quote.

Streetscape

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.

We confirm which approval pathway your Parramatta 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.

01

What is under the house

Your house was built to hold up one storey. A second floor roughly doubles what the foundations carry. A 1915 Parramatta 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.

02

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.

03

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.

04

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.

05

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 Parramatta. Better to know at the start than in week three.

06

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 Parramatta too.

Clear scope

What is included, and what is not.

Being upfront about both is exactly how we keep your fixed price genuinely fixed.

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 Parramatta the block usually gives you a real choice, and the age of the house often casts the deciding vote.

Go up

$3,500 to $5,500 per m²

Go up if the yard matters to you. Parramatta 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 post war Parramatta streets, and the conservation streets have their own rules we design for.

Extend out

$2,500 to $4,500 per m²

Extending out is a genuine option in Parramatta, 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 Parramatta 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.

Your Parramatta 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.

01

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.

02

Consultation & Build Cost Estimate

An experienced builder discusses your project and site, then prepares a detailed build cost estimate.

03

Preliminary Agreement

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.

05

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.

06

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.

07

Pre-Start Selections

Together, we finalise your fixtures, fittings and finishes with suppliers, so everything is confirmed before work begins.

08

Start of Construction

Your project manager meets you on site to confirm documentation, expectations and communication before works commence.

09

Construction

Your project manager oversees the build, coordinates trades and manages quality, keeping disruption to a minimum.

10

Good to know

Frequently asked questions.

How much does a second storey addition cost in Parramatta?
Our fixed price packages start from $274,000 (Essential), $304,000 (Family) and $320,000 (Complete), covering the new upper floor works including Hebel PowerFloor while the offer runs. Custom builds generally run $270,000 to $400,000. Design, engineering and council approvals are quoted separately as preliminaries, at roughly $30,000.
Do I need council approval for a second storey addition in Parramatta?
Parramatta second storey additions fall under the City of Parramatta. Homes outside the conservation areas often qualify for a Complying Development Certificate, which a private certifier can approve. Homes inside the conservation streets need a full Development Application. Which applies to your block is the first thing we confirm. We assess which applies and manage the approvals for you. Approval typically takes around 4 to 8 weeks.
Can you add a second storey to a Federation or post war home in Parramatta?
Yes to both, and they get there differently. Post war brick veneer is the straightforward case. A Federation home needs its footings and roof structure confirmed first, and on a conservation street the design has to sit with the original roofline, which is also what gets the DA approved.
Can my Parramatta house support a second storey?
It depends on the footings, the wall construction and the condition of the existing frame. Adding a floor roughly doubles the load the structure carries, and the clay soils through Parramatta, and footings that range from 1915 brick piers to 1970s strips, mean the engineer always checks before design. A structural engineer assesses this, and we arrange that assessment before giving you a fixed price.
What is Hebel PowerFloor and why is it included?
Hebel PowerFloor is a 75mm solid autoclaved aerated concrete floor panel, almost four times thicker than standard particleboard. It gives the upstairs a solid, concrete style feel underfoot, helps reduce noise transfer between levels, and is non combustible. We include it as standard on early Parramatta projects because it is a genuinely better floor.
Will I have to move out during construction?
Often you can stay, depending on the scope and whether ground floor works are involved. During the early structural stage, when the roof is off and the house is open to weather, there is usually a short period where it is safer to vacate. We set out that timing before we start.
How long does a second storey addition take?
As a general guide, construction runs around 12 to 24 weeks depending on size and complexity, with design and approvals beforehand. Larger builds that include ground floor works run longer. We give you a project specific timeframe once we have assessed your Epping home.
Does a second storey addition add value to a Parramatta home?
Adding bedrooms, bathrooms and living space in a suburb like Parramatta, with the CBD, the Metro and everything at the door, typically adds significant value. Factoring in stamp duty and moving costs, it is usually more cost effective than buying a larger home nearby. Adde, typically adds significant value, and you keep your land and location. Once you factor in stamp duty of roughly $40,000 on a million dollar purchase plus agent fees, it is usually more cost effective than buying a larger home.
What is not included in the package price?
The package covers the standard new upper floor works. Structural steel, footing upgrades, downstairs renovations, existing defect repairs, service upgrades and the design, engineering and approval preliminaries are assessed and quoted separately, so your fixed price stays genuinely fixed.
Are you licensed and insured?
Yes. Strava Group holds NSW Builder’s Licence 487370C and carries public liability insurance and Home Building Compensation Fund cover on residential work over the statutory threshold. You can verify the licence through Service NSW.
