The renovation story

An outdoor space that carries the same detail as the house

This Northbridge project is an external renovation built around an architecturally designed cabana, sitting alongside a new pool installed by another contractor. The work covers the cabana itself, the rear facade of the house, the paving through the pool surrounds, new fencing, and the stormwater infrastructure underneath all of it.

The cabana is the centrepiece. Its roof is carried on a custom steel frame standing on only two posts, engineered to cantilever so the structure reads as a floating plane rather than a pavilion boxed in by columns. The underside is lined in Trendplank spotted gum, which does most of the visual work: from underneath, the whole roof becomes a warm timber ceiling. Two Bromic radiant heaters are set into that ceiling so the space works through winter, and a kitchenette runs along one side.

The rear facade of the house was clad in recycled brick veneer to tie the new work back into the building. Recycled brick is slower to lay than new brick because the colour variation has to be sorted and distributed by eye as the courses go up, but it is the reason the extension does not look bolted on.

The part nobody sees

A new on-site stormwater detention basin sits under the works, along with the plumbing that feeds it. Adding a pool, a cabana roof and a large area of paving means far less rain soaks into the ground than before, so the council required a tank to hold the runoff and release it slowly. It was a condition of the development approval, and no occupation certificate would be issued without it.

We also engaged and coordinated the consultants the project needed, the structural engineers and designers whose documentation the construction certificate depended on. On a project with a two-post cantilever, that engineering is not paperwork, it is the reason the roof stands up.

A build run at the owner’s pace

This is a cost-plus contract, and the owner has chosen to stage the works over an extended period rather than run them as one continuous program. That is why a build of this scope has taken more than a year. It is slower and it costs more overall, because trades return to site across several mobilisations instead of attending once. In exchange the owner keeps full control of the pace and full visibility of every invoice.

If you are weighing up how to structure a project like this, our guide to comparing renovation quotes covers what to look for, and our post on why early builder involvement matters explains why the engineering on a structure like this cabana needs a builder in the room during design.

FAQs

Common questions about this project

Answers to the most common questions about this renovation, including costs, timelines, and materials.

Why has this project run for more than a year?

Because the owner chose to build it that way. This is a cost-plus contract and the works have been staged deliberately, with each phase commissioned as the owner was ready to proceed rather than run as one continuous program. A build of this scope could be delivered in a fraction of the time on a single continuous run. Staging it costs more in total, because trades return to site across multiple mobilisations rather than attending once, and it takes considerably longer. What it buys is control: the owner decides the pace and can pause between stages. It suits people who would rather build the whole thing properly over a longer period than compromise the scope to fit a shorter one. We explain how the two contract types differ in our guide to building contracts.

What does the price range cover?

The range of $300,000 to $400,000 covers the full external scope on this page: the architecturally designed cabana including its custom steel frame, spotted gum ceiling lining, kitchenette joinery and ceiling heaters, recycled brick veneer to the rear facade, luxury paving to the cabana and pool surrounds, new timber fencing, the new stormwater detention basin, and all consultant fees for the engineers and designers required to get the construction certificate. The pool itself was installed by another contractor and is not included.

What is an on-site stormwater detention basin, and why was one needed?

An on-site detention basin, usually shortened to OSD, is an underground tank that holds stormwater during heavy rain and releases it slowly into the council system instead of all at once. Councils require them when a development adds hard surfaces such as paving, roofing and pool surrounds, because those surfaces stop the ground absorbing rain the way it used to. On this project the OSD and its associated plumbing were a condition of the development approval, which means the occupation certificate could not be issued without it. It is a significant cost that never gets seen once it is finished, and it is exactly the sort of item that separates a real quote from an optimistic one.

How does a cabana roof stand on only two posts?

With a custom steel frame designed for it. Rather than ringing the structure with posts, the roof is carried on two columns with the frame engineered to cantilever out from them. That is what gives the cabana its open outlook to the pool with almost nothing interrupting the view. It requires a structural engineer involved from the design stage, which is why consultant fees form part of the scope on a job like this rather than being an afterthought.
