To go up or out…that’s the question.
Thinking of extending your home but not sure which direction to build? For many Melbourne homeowners, the idea of creating more space is exciting but deciding how to extend can be challenging. Do you build out the back? Expand to the side? Or go up and add a second storey?
If you’re planning home extensions in Brighton or anywhere in Melbourne’s inner or bayside suburbs, you might be wondering how exactly to proceed. Read on as we take a look at each extension type so you can make a more informed decision about a reno that will enhance both your home and your lifestyle.
Rear Extensions
Best for homes with generous backyards or rear laneways.
A rear extension is one of the most popular ways to expand a home, especially in eastern and bayside suburbs like Brighton where blocks are wide and gardens are generous. Extending out the back allows you to add open-plan living areas, larger kitchens, alfresco zones or even a home office all while maintaining your home’s street-facing character.
Pros:
Ideal for creating modern, light-filled living spaces
Keeps the original façade intact which is great for period homes
Can open up to outdoor entertaining areas seamlessly
Often easier to get council approval
Things to think about:
You’ll need enough backyard space to work with
Rear access may be needed for builders and materials
Garden space may be reduced
If your home’s layout feels cramped or disconnected, a rear extension can transform it into a spacious retreat perfect for everyday living and entertaining.
Side Extensions
Ideal for corner blocks or properties with wide side setbacks
If you have the luxury of space on one side of your property, a side extension can be an excellent way to add a bedroom, a second living area or even a garage or studio.
Pros:
Maintains backyard size
Good option for single-storey homes needing extra width
Can balance out asymmetrical floor plans
May improve natural light and cross-ventilation
Things to consider:
Side setbacks and council regulations may restrict your options
Matching existing rooflines can require clever design
If you’re after more room but don’t want to compromise on your backyard area, a side extension could be your best bet if you have the space.
Second-Storey Extensions
Great for smaller blocks or when you need significant extra space.
When your land footprint won’t allow you to build out, going up is a smart solution. A second-storey extension gives you the freedom to double your space without sacrificing your outdoor areas, making it a popular choice in Brighton and other established Melbourne suburbs where land is at a premium.
Pros:
Keeps your backyard space untouched
Adds significant value and appeal to your property
Perfect for separating living and sleeping zones
Ideal for families needing multiple bedrooms or a retreat
Things think about:
Can be more expensive due to structural engineering and complexity
May trigger additional planning approvals
Construction time can be longer
Access during the build may be more disruptive
If you’re considering a home renovation and you need to maximise your floor space without spreading out, a second storey gives you room to grow while maintaining a functional footprint below.
Which One Is Right for You?
Choosing between a rear, side or second-storey extension depends on several key factors but it will mainly come down to your block size and shape, your renovation goals, and also your budget.
A deep block lends itself to rear extensions, while a wide block may favour side extensions. Compact urban blocks often call for vertical solutions. Rear and side extensions typically cost less than second storey builds, but this can vary depending on materials, site access and design complexity.
It’s also important to remember that many period homes throughout Melbourne’s older suburbs may be subject to heritage overlays or have restrictions that may impact what’s possible.
