Alexandra Buchanan Architecture

North Warrandyte

North Warrandyte, Victoria

The house is sited on a raised plateau above the Yarra River at North Warrandyte, embedded within dense native bushland.

The building is shaped by topography, orientation and environmental constraints, with its position responding to solar access, view corridors and bushfire requirements within the site.

A twin butterfly roof structure defines the composition, its upward-folding planes extending to frame the tree canopy and sky while introducing high-level glazing that draws natural light deep into the interior.

The plan is organised as two separated wings, allowing the dwelling to open independently across the landscape and maintain clear separation between living zones, privacy and external access.

A restrained palette of stone, timber, glass and steel grounds the building within its setting. Locally resonant stone forms continuous walling elements that provide thermal mass and tactile continuity, allowing the architecture to settle into the bushland context.

Project details

Concept modelling

The siting and topography at Warrandyte required the architecture to negotiate a steep, tree-covered rock slope. The plan is developed as a sliding arrangement, organised to step across the terrain and respond to changes in level and outlook. Twin butterfly roof forms define the composition, structuring the section and mediating light, views and privacy across the dwelling.

Crafting the detail

Materiality, light and detail define the character of the house, expressed through a restrained and carefully resolved architectural language. A considered palette introduces texture and warmth, remaining deliberately controlled to avoid excess complexity.
