Babylon House—a name inspired by the mythical Tower of Babel—represents a unique and captivating building. Much like the unfinished mythical tower reaching toward the heavens, Babylon House climbs a rocky summit with a sense of grandeur. The new additions and alterations complete its journey, adding the final touches to a magical and whimsical place.

Originally designed by Edwin Kingsberry in the early 1950s, Babylon House sits on a ridge dividing Avalon and Pittwater, offering expansive vistas of the surrounding landscape. The design brief was deeply attuned to the "spirit of the place," honouring both Kingsberry’s eccentric vision and the natural majesty of the environment. Perched atop sandstone boulders and surrounded by mature Angophora trees, the house blends architecture with its natural context.

Working closely with the client and builder, design decisions were tested rigorously to preserve the house’s whimsical character while enhancing its liveability. The result is a coherent integration of old and new, where the existing charm is enriched by thoughtful additions.

Access to the site has been significantly improved with a new driveway leading to a sculptural two-carport, covered entirely with solar panels. A small two-person cable car provides stairless access to the main living terrace, preserving the existing 96 stone steps and natural landscape. The new kitchen, nestled beneath the existing roof, seamlessly connects the external patio, bar, and dining area, enhancing the flow between indoor and outdoor spaces.

The newly added main bedroom and study wing extend south of the grand circular room, capturing dramatic northern and east/west views. This wing is designed to step around hilltop boulders, cantilevering over the landscape to avoid disturbing the roots of the large Angophora tree. The careful siting minimizes excavation, allowing the natural beauty of the site to intrude into the rooms, creating a harmonious connection between the interior and stunning surrounding landscape.

The material palette for the new additions is a refined evolution of the original design. Black timber weatherboards and stone cladding echo the home’s existing materials, while terrazzo, pickled timber panels, and painted black ceiling timbers define the interior. These materials enhance the integration of old and new, creating a consistent link without replicating the original design.

Sustainability was a key consideration throughout the project. The integration of solar power, thoughtful material choices, and preservation of the site’s natural features reflect the home’s commitment to minimizing its environmental footprint. High quality craftsmanship and durable materials ensure that Babylon House will endure for generations, remaining both functional and beautiful. The design’s gentle approach to the landscape allows the new work to enhance the existing beauty while improving liveability.

The additions to Babylon House complete the vision of the mythical Tower of Babel. The original magic of the design has been preserved, while the updated amenities address the owners’ needs. This balance enables them to joyfully age in place, maintaining the whimsical and timeless character of the home.
