House Extension Ideas Australia

Oct 5, 2020

House extension ideas in Australia is a hot topic, especially with all the recent renovation incentives currently available!

However, finding the best house extension ideas in Australia can be very overwhelming as there are many factors to consider. For instance, location and temperament are, of course, of utmost importance! In this article, we will uncover some of the most interesting house extension ideas in Australia - and perhaps borrow some ideas from our stylish Northern Hemisphere counterparts.

Small House Extension Ideas

Even if you have a small budget or little room space, you can still boost the value and space of your home. Check out some small house extension ideas below that can help you make a big impact:

Build an orangery

Looking to create that perfect balance between a conservatory and an extension? Add an orangery. Create a mix of solid roof and solid walls with a glazed roof lantern. In contrast with a conservatory, you'll enjoy better insulation and temperature control if you are in the colder climates of Australia.

Add an enclosed porch

Does your front door open straight up into your living room? Adding an enclosed porch can be a useful shield against the elements. It’s also a great addition if you want to add a more spacious feel to a small hallway.

Add a bay window extension

This doesn’t necessarily require any foundations. By cantilevering a projecting bay window extension on existing structure brackets, you can enlarge a room. Get extra light into the room by installing windows on three sides to enhance the feeling of spaciousness.

Under house transformations

Utilise your space with an under house renovation or basement conversion. For those dark areas add more light by introducing a small glazed extension. This should make it look lighter and larger. The addition doesn’t need more than a modest scale. You’ll love it even more if it opens onto a sunken courtyard that comes with stairs that lead up to your garden.

Rear House Extension Ideas

This section of house extension ideas should interest you if you would like to add more value to your property. The rear of your home can also come in handy if you need more room when you start running out of space. Consider some inspirational rear extension ideas:

Bring the outside in

Connecting your outdoor area and living room using open-plan living areas is a creative extension idea. Such an open-plan area that opens right onto your outdoor living area has become popular. For the perfect entertaining setup, build an undercover alfresco dining area that makes your kitchen easily accessible. 

Add a separate studio residence

For those who want extra space for accommodating guests or something like a separate office, adding a separate studio (aka the Luxury Granny flat) in the backyard sounds superb. Across Australian backyards, there’s now a trend of granny flats popping up. So, it makes sense to create a separate studio space, especially now that flexible working arrangements are becoming the norm.

Dig into the basement

In this case, you have to dig out a basement but it's worth the time and effort. You should free up some space, making it easy to install an impressive big kitchen. Or you can choose to have a large cinema room created. Basements make it possible to add more space to extensions. 

Transformative house extension ideas

Most people tend to go with the conventional style of having their extension match the existing architectural style. But who says your extension can’t have its own unique design? Transformative rear extensions allow you to incorporate a contemporary house style to your home.

Modern House Extension Ideas

Traditional homes are nice. But guess what's even cooler? A modern house extension! When an extension is designed so well that it offers modern comforts and extra space, it can be a positive, life-enhancing experience. These standouts below should provide enough inspiration if you seek modern house extension ideas Australia:

Create a parents’ retreat

It’s okay to get yourself a new master bedroom. But you get so much more luxury by adding a parents' retreat. A good idea would be to build it as a rear extension. Check to see if you got enough space and then you can make sure your design includes walk-in wardrobes. Don't forget to create enough room to accommodate a sofa or an armchair in your bedroom and that's all you need to embark on the ultimate adult’s hideaway.

Add a bathroom

We know that discussions about extensions do not include an extra bathroom sometimes. You already know that an extra bathroom can boost your home's resale value but that's not all. Think how smoother life will become for your large family if you have another bathroom too. 

Build a garden room

It's possible to design outbuildings of varying styles. You can then use it as an extra living room, an in-house gym, or a separate garden office. 

Some Queenslander Extension Idea

Most of the time, Queenslanders lack sufficient height to make the lower floor space useful. They usually fail to meet the building standards and requirements for height. But that doesn’t mean your Queenslander extension dreams can’t become a reality.

You can still use the low height underfloor spaces to create extra storage compartments. They can also help supply extra space in car parking and cellars. And you can do all of that without incurring the costs of rectification and excavation which can be unpredictable.

Extension renovation underneath the house

But if you have the budget and crave some extra space, you can raise the home and build underneath it within the existing footprint. Try building a pavilion extension instead if you have sufficient land size. With that, you can create a modern house extension and get it in sync with your dream garden.
