Discover the elegant harmony of a single story house plan

The design of a single story house is a balancing act between space and flow. Every room has its own spacial requirements decided, naturally, by the people living in them. But palatial rooms placed haphazardly, without consideration for movement, lighting, privacy, noise or view, simply will not do.

'We've outgrown our home, but we love it too much to leave.' It's a common refrain amongst single story home owners, and a fair reason to consider a renovation or extension plan. If you love your home, neither a growing family or new working conditions should drive you to leave. Rather, see them as an opportunity to adapt. A consult with our specialists will leave you with options on how to get the most out of each room individually, and out of your home as a whole.


This is an opportunity for your home to totally embody your needs and interests. Let's talk about how best to redesign your space to focus on what matters to you.

Consider the keen gardeners living in this Fairfield home. On top of demolishing and moving the master bedroom to a more natural position, we also redeveloped the living room and garden areas to better suit their passion. Their new family and dining areas opened onto a larger garden via gorgeous French doors, with highlight windows letting in the morning sun, giving them the chance to finally enjoy their garden the way they wanted to.


Sometimes it's a simple matter of consistency. If you live in an older home that's seen its fair share of work, you might've noticed inconsistencies across decades worth of renovations. You might find its design elements and layout archaic and ill-suited to your needs. Our single story plans can be as extensive or as subtle as you need; we can extend, or we can demolish and rebuild. The possibilities are bound by your creativity — the logistics are bound by ours.


With the guidance of our design specialists, the price of a single story extension could sit as low as $130,000. It's worth considering, especially when held up to the value added to your home.

This Coburg home had already had an extension, but it didn't quite bring out the home's full potential. Our proposal for an open plan living area, combined with a renovated master bedroom, with exterior work all around for consistency, is clear proof of how much value the right plan can add.

How much does a single storey home renovation cost?

Consider $130,000 as a working figure, but the truth is that it’s an impossible question to answer without a clear idea of what it is you want. Our specialists are more than happy to start defining that idea with you with a free design consultation.

There is a common notion that home renovations always cost a bomb, and it just isn’t true. Depending on your needs and the contractor, renovations and extensions can be perfectly affordable.

How long will the single storey renovation process take to complete?

Likely between 6–12 months. But, as with cost, it really does depend on what you want.

To be clear, you do not necessarily have to leave your home for the duration of construction. Depending on the work being done and the ammenities safe for you to use, it’s possible for you to live at home for most — if not all — of construction.

What are the steps for a single storey renovation?

With decades of experience behind us, our workflow is as seamless as our construction is flawless. These are the steps you can expect:

  1. Research and planning: We’ll discuss your ideas and our own, bringing them to life with a 3D conceptual model you can mull over and approve.
  2. Pre-construction: Design approved, we’ll start work on the necessary applications, select our tradespeople, purchase materials, and seek council approval.
  3. Construction: With a clear budget and timeline, we roll up our sleeves and get to it.

We guarantee you that we will remain transparent and available from start to finish. Have a look through our testimonials, and know that your satisfaction is our absolute priority.
