    Adding a second storey to a house

    Besides adding a whole new floor of space, double-storey extensions will significantly boost the kerb appeal and value of your property, making it a great investment for the future. Adding a second storey to your house also offers the following advantages:

    • Great views from the upper level, ideal for bedrooms or recreational space
    • Leaves your garden or backyard untouched
    • In some cases it can avoid foundation or excavation work

     

    What to consider before building

    1. Local Building Regulations

    The first thing you need to do before beginning construction work is to check with your local council about specific regulations for adding another level to your house. These may include height or design restrictions.

    2. Your Foundation

    Equally important is checking whether your existing foundations are capable of supporting the weight of another level. Not all single-storey properties can hold up another floor.

    3. Construction Time

    Depending on the new floor design and how elaborate the renovation will be, your second storey extension could take anywhere from a few months to a year or more to complete. It’s best to agree on the timeline with our construction team beforehand so you have realistic expectations.

    4. Alternative Living Arrangements

    Bear in mind that you might have to find temporary living quarters if the renovation gets too extensive or disruptive. Again, this should be discussed with our team before they commence construction so you can plan ahead accordingly.
     

    How Much Does a Second Storey Extension Cost in Australia?

    The cost of an upstairs extension depends on its size, style,  design,  access  and the materials used, and the overall condition of your home. The average cost of a two storey extension in Melbourne ranges between $340,000 and $640,000.

    Second Storey VS Knock-Down Rebuild

    Opting for a knock-down rebuild lets you start fresh with a custom-designed house, but it may be more expensive and you'll lose the old property's character and history.

    Conversely, adding a second storey preserves the unique charm of an older home, but structural limitations apply. Your choice depends on how much change you want and local building regulations, which could restrict demolition or additional levels.

     
     

    Is It Worth Adding a Second Storey?

    If you’re on the fence about adding a 2nd storey to your house, here are a few compelling reasons to do it:

    • Significantly increases your floor space
    • Avoids disrupting your garden or backyard area
    • Adds dimension and grandeur to your house
    • Increases natural insulation to your lower level

    Build Out OR Build Up?

    House owners often face a dilemma when considering an extension: build out (expand current floor space) or build up (add another floor)?

    Each option has pros and cons, with ground floor extensions potentially incurring costly excavation, disposal, and foundation work.
