Rear House Extensions for your Dream Melbourne Home

Adding square footage to the back of your house instantly increases living space, improves functionality, and boosts your property value. But with so many possibilities, choosing the right type of extension can feel overwhelming.

Single vs. Double Storey Rear Extensions

First things first: size matters! The most fundamental decision is whether to single-handedly conquer the space battle with a single storey extension or scale the heights of luxury with a double storey rear extension.

Single Storey Rear Extension

Imagine a sprawling kitchen-diner opening into a sun-drenched garden, seamlessly blending indoor and outdoor living. Or picture a dedicated playroom or home office bathed in natural light. A single storey extension is perfect for maximising ground floor space, ideal for creating larger kitchens, dining areas, family rooms, or even guest bedrooms. It’s the ideal choice for budget-conscious individuals seeking functional space without extensive construction.

Double Storey Rear Extension

Picture a light-filled second floor extension housing a luxurious master suite or additional bedrooms, while the ground floor boasts a spacious kitchen and living area. Need a home office or gym? Double storey extensions have you covered. This option offers the ultimate in expansion, adding significant value to your home and unlocking a world of possibilities.

Designing Your Rear House Extension

We believe your type of extension should be as unique as you are. We offer a plethora of design options to complement your existing home’s style and seamlessly integrate into your property.

Making Your Extension Your Own

Rear House Extension FAQs

Should I get a single or double storey rear extension?

This depends on your needs and budget. A single storey extension (ground floor only) is perfect for creating a spacious kitchen, dining area, or family room. A double storey extension offers even more possibilities, adding a bedroom extension, bathroom extension, or even a home office on the first floor. It’s an investment, but significantly increases your home’s value.

Do I need planning permission for a rear extension?

Not always! Under permitted development rules, you can build certain extensions without permission. Extensions Unlimited is well-versed in these regulations and can advise you on your specific situation. We can also handle the planning application process if needed, taking the stress off your shoulders.
