The Grotto: Brutalist Architecture Meets Biophilic Design in This Modern Masterpiece

House Tour

ABI Interiors

Beautifully bold and functional, Kasso Constructions’ The Grotto is an inspirational abode that introduces biophilic design to soften its brutalist architecture. Strategically split over three levels, it offers an enticing prospect full of hidden surprises. 

As we will discover, the home’s harmonious connection to nature, considered use of raw materials, and implementation of ABI Interiors’ brushed gunmetal fixtures throughout contribute to its aesthetic brilliance.

Stepping inside The Grotto, you instantly appreciate how the architect was inspired by the cozy confines of caves when configuring this space. A seamless transition from outdoor to indoor is established with a hall-length curved window that overlooks idyllic tropical gardens. True to the spirit of biophilic design, a welcoming seating area stretches the length of this window — providing the perfect reading nook.

An internal courtyard from the spacious kitchen-living area also invites the outdoors in. Raw materiality brings an additional edge with limestone flooring and textured white walls. There’s also a ceiling made of concrete inlaid with the texture of timber boards — adding a unique beige undertone to the predominantly grey scheme.    


A thoughtfully designed kitchen island that accommodates booth seating into the bench is superb in its space-saving functionality. ABI Interiors’ Ohelu Single Kitchen Sink and Elysian Kitchen Mixer in brushed gunmetal introduce further functionality.

Connected to the living space is a tranquil outdoor entertainment area, where the angular formwork above the L-shaped pool allows dangling vines to contribute to the rainforest ambience.

The owners envisioned a hotel-like feel for the guest wing, which was beautifully realised in the architectural stone vanity that’s uniquely positioned outside the ensuite. The basement offers further surprises, including a wine cellar, mudroom, and a spacious cinema room.

Venturing upstairs, you have the master bedroom, with mirrored wardrobe cabinetry magically elongating the space. The ensuite feels cohesive with the rest of the home, with limestone walls, a dolomite stone vanity, and the continuation of timeless brushed gunmetal tapware. In addition, smaller fixtures like ABI Interiors’ Davis Door Handle and glass hardware like the Kenzie Glass to Glass Shower Hinge contrast perfectly with the neutral colour palette.

The kids are accommodated, too, with a ‘children’s wing’ that includes a bedroom with a padded raised ledge and a convenient connecting door to the other bedroom. The thoughtful inclusion of a generous kids’ seating space and a refreshing alfresco area adds to the continuous surprises that make The Grotto so intriguing.

A testament to the clever hybridity of brutalist architecture and biophilic design, The Grotto’s connection to nature ensures warmth and tranquillity are integral to its robust design. This layered, continuously revealing home, uniquely inspired by caves and caverns, is an extraordinary design feat.
