Featured Projects

Calderwood Custom Home Moody Farmhouse Build

A three-bedroom, 240-square-metre custom home delivered in eight months. The brief called for a moody farmhouse palette with rich tones, textured materials and considered detail. The client knew exactly what they wanted, and the result is a home with genuine personality. See the full Calderwood custom home build.

Woonona Duplex

Our most photographed duplex build to date. A two-home luxury development in Woonona showcasing the coastal-modern aesthetic that defines a lot of our Illawarra work, with custom joinery, considered street presence and high-end internal finishes throughout. View the full Woonona luxury duplex project.

Oak Flats Detached Dual Occupancy

A detached dual occupancy on Miller Street with two standalone homes on a single block, each with its own front door, garden and address. A strong example of how dual occupancy can deliver multigenerational living or a long-term investment outcome without the compromise of a shared wall. View the Miller Street detached dual occupancy project.

Woonona Custom Home — Lang Street Knock-Down-Rebuild

A knock-down-rebuild in Woonona where the owner kept the street and the suburb they loved, and replaced the original house with a new custom home built around the way they live now. A textbook example of how a knock-down-rebuild works in established Illawarra suburbs. See the Woonona custom home build.

Most custom homes we deliver run between eight and twelve months on site, depending on size, finishes, and council approval timelines. Calderwood was an eight-month build. A complex coastal home with bushfire attack level requirements, custom joinery and detailed landscaping can stretch closer to twelve. Council development application or complying development certificate processing time sits on top of build time, and varies by council and site.
A duplex is two homes attached, sharing a party wall, on a single title or two subdivided titles. A dual occupancy is two separate homes on one block, often detached, also on one or two titles depending on the council and the build. Both need their own approvals and engineering. Which option works on your land depends on the site, the zoning, and the council.
Depending on size, site, finishes and complexity. We give clients an indicative figure early in the conversation, before any contracts, so you know whether the project is realistic for your budget before going further. Get in contact if you have a set of plans.
Yes. Most of the Illawarra has some slope to it, and many of our projects involve retaining, split-level design, or bushfire attack level requirements. We've worked across coastal, escarpment, suburban and rural-residential blocks.
