Get the most out of your home with a rear house extension

As your family grows and changes, housing needs can change as well. Having a big back garden is important when you have young children, but as your family gets older there's usually loud demand for everybody to have their own bedroom! Then, after the kids move out, other ideas might take precedence, like setting up a private study, or a home gym.

To facilitate these changes, one option is to move house into a property that better suits your new needs. But a better alternative might be a rear house extension. At Supa Group, we've carried out countless extensions and renovations and can help you get the most out of your home.

There are heaps of fantastic rear house extension ideas: from ensuites and new bedrooms to expanded living rooms and home offices. Big backyards are typically Australian, so rear extensions can present an easy and affordable way to improve many properties. It's one of the benefits of working with a company like Supa Group — we weigh up the options and tailor the most cost effective solution to meet your families needs.

Will a rear house extension interfere with heritage overlay?

Many homes across Melbourne are protected by heritage restrictions. These protections are designed to protect Melbourne's rich and unique architectural character. As a result, there are certain kinds of renovations that cannot be undertaken in certain homes.

However, rear house extensions are one of the easier kinds of renovation to get approved for heritage-listed addresses. A rear house extension doesn't interfere with the historic facade of a home and will have little to no impact on the way a property looks from the street.

Book in for a free consultation with our design team, and they'll be able to establish whether or not a rear home extension is possible at your address.

What are the stages of a rear house extension?

We follow the same tried and tested process for all of the house extensions and renovations we undertake.

  1. The Design Phase: You have the opportunity to speak with our team of designers, and describe everything that you want to get out of the renovations.
  2. The Contract Preparation Phase: We will organise all the relevant documentation and council permits. Then, after evaluating the job, we'll establish a contract and a set timeframe for construction.
  3. The Build Phase: Our build team will get to work on your home, and carry out your rear house extension with the utmost professionalism.

Can my family continue living at home during a rear house extension?

Most of our clients choose to stay in their home while we are building. However, there are instances where this is not practical, particularly if the kitchen, bathroom, or laundry amenities are decommissioned during the demolition process.

Clients also need to appreciate that we can be more efficient and therefore quicker if they are not occupying the home while we are working.

How much will my rear house extension cost?

The cost of an extension or renovation is contingent on several factors, like the size or the job, the materials required, and any locational challenges. However, we always strive to make our work as affordable as possible. This is the skill of our design consultants - they understand the factors that influence cost and can design to suit your budget. Before starting work, we'll provide you with a detailed quote.
