Cost of Adding a Second Storey to a House in North Sydney

When you’ve outgrown your home, first think about renovation before relocation. In many cases, adding a second storey to your home can be more cost effective and hassle-free than buying a new house. Read on to get acquainted with the costs involved in adding a second floor to your home.

Why add a second storey?

There are a number of effective home extensions available, adding a second floor to your house can double your living space without cutting into the rest of your property. Thus, it’s ideal for homeowners who don’t have a whole lot of land to work with.

In Australia, people living in bigger cities like Sydney and Melbourne often opt for a second storey addition because their space is limited to extend outwards. In North Sydney, many of the homes are brick and have sturdy foundations, which makes adding a second floor easier.

Considerations that affect the final cost

There are a variety of factors that contribute to second storey extension costs:

Foundation

First things first, is your house even capable of having a second storey added? You’ll need an inspection to check your home’s foundations to determine whether a second storey is the best way to proceed. If you need groundwork done on your property to solidify the foundation, this can drive up the overall cost.

Building restrictions

Before you begin any planning, check with your zoning codes to see if there are any height restrictions in your area. If there are, a second storey might not be the best option for you.

Design

Determine the overall look you’d like to achieve, as well as your desired square meterage. Having professional guidance from an architect is helpful here, as they can assess your home and let you know what is needed structurally for your second storey addition.

Timeline

This factor is a major one, because the longer your extension takes to build, the higher the final cost. In order to avoid overcapitalisation, you will want to know beforehand an approximate timeline so you can plan accordingly. Working with a professional like Refresh can help to mitigate the risk of a budget blowout.

Tradies

Don’t bother taking the shortcut of hiring mediocre tradespeople. After all, your second storey addition should add value to your home with quality workmanship. Our Renovation Consultants have access to a network of trustworthy contractors and suppliers in North Sydney to get you the greatest result for the best price.

Temporary relocation

Adding a second storey comes with plenty of ruckus, and it could affect your daily life or be unsafe to live amongst. So in some cases, you will need to move out of your home while your renovation is underway.

Your Renovation Consultant will go over these factors with you as they pertain to your specific project. From there, you’ll have a better idea of the costs involved.

How much will my second storey addition cost?

The average total cost for a second storey addition in North Sydney sits between $200,000 to $450,000*. This price fluctuates depending on the size of your home, structural requirements, and the quality of materials and finishes.

To break it down, it typically costs $1,850 to $15,000* per square metre. But again, that depends on your specific situation.
