OUR CLIENT’S REQUIREMENTS: My clients, newly arrived in Brisbane from Melbourne, wanted to create a family home. However, they were on a restricted budget and realised that they could not afford to do everything they would have liked to have done.

During lengthy discussions through our Lifestyle Design Advice verbal consultation, we explored a number of different options. My advice at the end of this time was that a pavilion style extension was best. This option actually limited the amount of renovation required and worked perfectly with the site restriction which included a Queenslander home at the front and a narrow driveway for access to the back. There was also a large pool traversing the rear yard space diagonally behind the Queenslander home.  My clients wanted a WOW factor and really liked the idea of adding a modernly styled pavilion to the back of their 1920-30’s colonial home.

THE PROJECT: So with the front of the home more or less off limits our attention turned to the back of the home; a
space that had a lot of potential. As mentioned there was an existing swimming pool that had been built diagonally across the backyard. This represented a potential challenge as demolishing and rebuilding the pool would add a considerable amount of expense to the project.

But this is where clever design can really help as we decided to add the rear extension around the pool so it could remain intact.061005_Hamilton_04

The extension was designed as a metal-clad pavilion with the view to creating a planned contrast to the existing structure. The bedrooms and bathrooms were relocated to the rear of the home to better suit the lifestyle needs of the owner’s and their children. This decision was particularly popular with their 14-year-old daughter who gained her own private balcony overlooking the backyard as part of the renovation.

Situated at a slightly higher elevation than the original home, the new extension is accessed via steps coming from the original hallway.  The open plan area houses a kitchen, lounge room, dining area and stunning indoor/outdoor room come deck. Concertina doors allow the deck to be closed off from the interior, or they can be quickly and easily swung away, blurring the lines between what is inside and what is out.

This new area is amazingly spacious with plenty of room even when a large crowd of people have gathered, which given the beauty of the space could be quite often.

The view from the rear of the home is gorgeous and the space is so inviting the owners have found themselves spending more and more time there.
The blending of spaces between the original home and the newly added renovation is perfect, with the owner’s goals being well and truly achieved. Overall the project has been a stunning success.

THE DESIGN PROCESS: We started out providing our clients with a verbal advice service and then the clients agreed to upgrade this to our sketch design concept. Our client had used another architect for their Melbourne home in the past and was familiar with an architectural process.  As a result, they quickly decided to engage us to complete our architectural service as well as taking advantage of our interior design services.

We provided a complete service 1 through to 6 explained in our architectural process.


As this is a character home in a demolition controlled precinct and we had proposed to add a garage on the side of the house, a development application needed to be lodged.

As part of our complete project managed service, we prepared the development application and managed our private town planning consultant who prepared the associated planning report. Through working together we were able to ensure the application was successful.

On approval, we then prepared the building application and lodged this application with our private certifier and also managed this application through to approval.

THE TENDER AND ADMINISTRATION PHASE: On behalf of our client we called tenders from 3 of our known builders. As typically happens we received a fair range in the prices back from the competing builders.  On acceptance of one of the tendered results we executed the contract ABIC-SBW1 FOR Housing in Queensland and then managed the process from start to completion.

The works were completed in a total time of 26 weeks and there was less than 1% of variation in the total price. The only variation, in fact, was to do with the incorporation of some extra stormwater drainage at the side of the existing house.

Whenever we have clients who are on a strict budget we look for all possible ways to reduce their costs. This can sometimes be done via working our contracts to accommodate any work, or goods, that the owner can supply. In this case, our client was able to save themselves some money by doing all of the painting work themselves.
