2025 @hia_southaustralia Custom built home over $2 million award winners. 

We have taken out the win in a very prestigious category for our stunning custom home at 20 Tranmere — a home that makes a statement from the moment you lay your eyes on it. 

This home tested everything—design, detail, timing and trust. We couldn’t have done it without our clients who backed our process, and the trades and suppliers who gave it their all. Built with pride, delivered with precision.

20 Tranmere — the home that saw us take out the @hia_southaustralia award for best custom home over $2 million. We’re so proud of this achievement, this home is noting less than breathtaking and we feel it got the recognition deserved. 

Take a walk through brutalist-inspired form, grounded in modern minimalism.
Concrete, timber, and stone in quiet contrast—raw, refined, and deeply intentional.

20 Tranmere — Dark, refined, and unapologetically simple. The kind of ensuite and bathroom that doesn’t need to shout to be heard.

20 Tranmere — the living and dining areas come together in a beautiful cohesive open plan — anchored by a double-sided split stone Venetian plaster fireplace. Bathed in natural light, it creates a bold yet timeless focal point, seamlessly connecting the heart of the home.

20 Tranmere — bold contrast and heavy looking structures with a strong mix of materials from formed concrete to black alucabond cladding, softened by the timber-lined alfresco ceiling. Theres an effortless flow with the design of this home and a sense of laid-back luxury.⁠

It’s not every day that you would describe a hallway as a masterpiece, but 20 Tranmere certainly fits into that category. Enter through the 4m pivot door, you’re greeted with formed concrete walls to the left, and joinery panelling to the right, beautiful herringbone timber floors pair well with the harshness of a steel frame door. It’s minimal in nature but it packs a punch.

20 Tranmere — Contrasting textures and bold lines define the stairwell in a harmonious blend of material sophistication. @polytec Boston Oak timber joinery envelops the stairwell, while a black steel balustrade and formed concrete walls introduces striking contrast and definition.

20 Tranmere — sculptural, refined, minimalism with a beautifully layered material palette in the heart of this home. 

The hero is the oversized natural stone island bench crafted by @uniqstone that grounds the space.

It’s the details at 20 Tranmere that make this home stand out from the rest. Full-height frameless windows dissolve the boundary between indoors and the garden beyond, while the timber batten ceiling adds warmth, the formed concrete adds a raw edge. Every detail curated for flow, light, and quiet sophistication.
