On the fringe of the Berowra Valley National Park and extensive Hawkesbury River wilderness and waterways, Wedgetail is designed as a protected, contemplative space, referencing  "secret" natural bush caves that have provided shelter and refuge for the local first nations peoples for millenia. The space is quiet and "heavy", the structure deliberately anchored into the hill like an ancient rock cave, the compressed edge framing the view by restricting the apeture to the tree canopy beyond.

The space is designed to be at once calming and confronting, seeking to subtly "force" the occupants to become aware of smells, sights and sounds of their immediate surroundings and the landscape beyond - the wind, water, atmosphere and temperature - the contrasting weight and lightness of the space.

Constructed from recycled board-form concrete, the cantilevered edge is impossibly thin and disappears to the sky beyond. The raking and stepped soffit was expertly formed on-site by carpenters and is deliberately rough and imperfect to defer to the surrounding bush and sandstone rock shelves.

The landscaped roof creates a second opportunity for learning and gathering, with the experience of soaring into the tree canopy and sky beyond. The structure is deliberately heavy and buried, and in-time will be engulfed by the landscape such that it disappears into a secret cave from where the design as born.
