Minor Dwelling and Alteration Cockle Bay

The Architectural Challenge

This project involved a complex intervention on a suburban Cockle Bay site that had undergone multiple unstructured extensions over several decades. The brief required a two-fold solution: to structurally resolve and upgrade the existing main dwelling's garaging, while introducing a completely independent, self-contained minor dwelling on the same property. The core architectural challenge was to establish distinct identities and absolute privacy for two separate households on a single title.

Architectural Separation and Identity

Our design response utilizes the site’s dual-road frontage to split the access completely. The new minor dwelling was positioned to face the secondary roadway, giving it a private entrance and its own clear street address. To ensure the new addition didn't compete with the original house, it was designed with a distinctly different, modern architectural character, featuring its own private orientation away from the main family living zones.

Conversely, the garage extension was designed to unify the original home. It adopts the traditional weatherboard cladding of the primary structure, seamlessly integrating the new footprint into the existing building fabric and resolving the home’s street-facing elevation. The rooflines were designed to follow the slope of the site and the road, allowing it to feel cohesive with the neighbourhood.

Spatial Independence

The layout relies on strategic massing and screening to create an acoustic and visual boundary between the two homes. By carefully managing the orientation of windows, outdoor living areas, and entry pathways, both the primary residence and the minor dwelling maintain absolute independence. The completed project demonstrates how clever site logic can maximize land density and provide flexible family living without sacrificing individual privacy.
