Why Choose Us?
Second Story Addition Specialists Sydney
Before we plan what goes upstairs, we establish what the existing home can support. A structural engineer assesses the home and identifies any strengthening needed, so that work can be included in the plans and budget before construction begins. We talk you through the findings and the practical options, helping you understand how each approach could affect the design and cost.
Our experience with structural renovations helps us coordinate that work with the new level. As the plans develop, we’ll discuss the key decisions with you and recommend an approach that suits both the home and what you want from the extra space. You’ll know how the addition will be supported and what’s involved in building it before work gets underway.
Here’s what our experienced renovation builders bring to your second storey addition:

Your Second Storey Addition in 4 Simple Steps
1. FREE ONSITE BUILDERS CONSULTATION
Call or send us some details about the second storey you’re considering, and we’ll arrange a time to inspect your home. We’ll discuss the rooms you need, how the new level could connect to the existing house and your budget. We’ll then give you a preliminary estimate, with any structural assumptions to be checked during planning.
2. Design and Planning
We develop the design and arrange a structural assessment to determine how the existing home can support the new level and whether strengthening is needed. We also work through the relevant site and approval requirements. Once the design, structural work, finishes and full scope are clear, we prepare a detailed fixed quote for you to review before construction begins.
3. Construction
Your dedicated project manager sequences ground floor reinforcement, framing for the new level, and the finishing trades that follow, keeping you updated as each stage is signed off. Depending on the scope, you may be able to stay in part of the house while the work progresses upstairs.
4. Handover
Once the addition is complete, we walk you through the finished upper level and handle any final details before signing off. You’re left with a home that’s genuinely grown to fit your family, with a ground floor that’s as structurally sound as the new level built on top of it.

6 Benefits of a Second Storey Extension
Double the Living Space
Adding a full second storey can effectively double a home’s usable floor space, without reducing the block or the garden the family already enjoys.
Room to Grow
Extra bedrooms, a second living area or a proper home office give a growing household space to spread out, rather than everyone sharing what’s already there.
Keep the Yard You Have
Building up instead of out means the backyard, garden and outdoor entertaining space stay exactly as they are, with all the new space added above rather than across the block.
A Stronger Home Overall
Reinforcing the ground floor to carry a second storey also strengthens the existing structure underneath it, leaving the whole house more solid than it was before the addition began.
Added Property Value
A well-executed second story addition adds substantial floor space and function, which tends to lift a property’s value more than almost any other type of renovation.
A HOME THAT FEELS NEW
A second storey can change far more than your floor space. With a new layout, a different outlook and rooms designed around how you live now, the whole home can feel renewed, while you stay in the place you love.

2nd Storey Home Extensions FAQs
What is the cost of adding a second story to a house in Sydney?
The cost of adding a second storey to a house in Sydney depends heavily on how much the existing ground floor needs reinforcing, the size of the new level, and the finish standard you choose throughout. A partial second storey addition over an existing garage, for example, is generally more cost-effective than a full second storey across the whole footprint, since less of the ground floor needs structural work.
Costs can vary considerably from one home to another, so an estimate based on your property, the proposed design and any structural work needed will give you a much clearer picture than a general price guide.
Call (02) 9000 1888 and we’ll come out to assess your property and provide a free estimate.
How long does adding a second story take?
Timeframes vary depending on the scope, but as a general guide, a second storey addition typically takes somewhere between 4 and 8 months of construction once building starts, longer than a comparable single storey extension because of the ground floor reinforcement and additional structural work involved. Design and approval time sits on top of that, and depends on which approval pathway your addition needs.
We discuss your timeline in detail as part of the consultation process, so get in touch and we’ll give you a clearer picture for your project.
What types of houses are best suited to 2nd storey additions?
Single storey homes with a solid existing footprint and ground floor structure are generally the best candidates for 2nd storey additions, since less reinforcement work is needed to carry the new level. Older homes can still be strengthened to carry a second storey, but the assessment and reinforcement scope is usually greater than for a more recently built home, which is something we confirm early rather than partway through construction.
Should I add a first floor addition or a second storey addition?
A first floor addition, or ground floor extension, expands your home across the block. It can create more living space with a direct connection to the backyard, but it will use some of your outdoor space. A second storey addition builds upwards, leaving more of the yard intact while adding room for bedrooms, a study or another living area.
The better choice depends on your block, the space you need, your budget and what the existing home can support. We’ll help you compare the options and choose an approach that works for your property. Get in touch to discuss your plans.
Does the whole ground floor need to be reinforced for a second storey addition?
Not always. Where a second storey addition covers only part of the house, above a garage or a single wing, only the ground floor structure directly underneath the new level typically needs reinforcing, rather than the whole footprint. A full second storey extension across the entire house generally needs a more complete structural assessment, since every part of the ground floor is now carrying additional load.
Call (02) 9000 1888 and we can assess exactly what your ground floor will need before you commit to a design.
