Extra space

Older homes have been designed and built to meet the expectations of past generations. But nowadays, households have different needs, different demands. Especially when it comes to space. With a custom renovation or extension, you can make your home spacious the way the people of today like it.


Our custom renovations and extensions are an opportunity to make your home into everything you've ever dreamed. It can have all the convenience and comfort you've ever desired. Want a home theatre room? Boom. It's in. Need a meditation space? Bang. It's done. You have total freedom to live the way you want.  

Aesthetic cohesion

Homes that are older have often been renovated piecemeal through the years. As a result, their aesthetic is unfocused and confused. They lack unity and beauty. A custom renovation provides the opportunity to start from scratch, so that your home has the sophisticated look of organic uniformity. Planned as an entire structure from the outset, it will dazzle.

Lower power bills

One of the advantages of a custom home renovation is that it will lead to a more energy-efficient home. By replacing old and worn doors and windows, your home will maintain its temperature more consistently in winter and summer, meaning less expensive heating and cooling bills. Not only will visitors to your house love your revamped place, your wallet will too.

How much do custom home renovations cost?

Understandably, the expense of a custom home renovation is a big consideration. It is a major investment and not a financial decision to be taken lightly. That said, without a design it's difficult to provide an exact figure. The cost of the build will vary based on many factors. We will be able to give you a precise quote following a free design consultation.

How long will it take to complete my custom home renovation?

The time frame for completing a custom home renovation depends on numerous factors. In general, you can expect it to be finalised within 6 months from design to completion. Once you've settled on a design, we will be able to nail down a specific timeline.

What are the steps for a custom home renovation?
