Spiegal House

Spiegel House

Another amazing private residence project added to our portfolio!

The award-winning Spiegel House, realised with the expertise of Carter Williamson Architects, redefines suburban living in Sydney. This innovative residence showcases visionary homeownership, blending theatrical design with meticulous material craftsmanship. Designed to accommodate multiple generations, the Spiegel Haus boasts intricate material details and environmentally conscious design, providing an ideal home for a dynamic young family.

In this endeavour, Keystone Linings seamlessly integrated our Key R-Line Grooved MDF Panels, exquisitely pre-finished in white. These panels not only introduced a distinctive focal point within the media room but also served as an exceptional acoustic solution, elevating the functionality and aesthetics of the space.

The sense of pride runs deep as we recall our contribution to this project, characterised by its outstanding design and the remarkable synergy among a team of skilled professionals.
