Home Extension Mellons Bay

The Architectural Context and Site Challenges

This project involved the architectural addition to of an existing Lockwood residence situated on an steep bush site. Lockwood structures present a distinct construction logic that can be highly restrictive to alter. Rather than attempting to replicate the original solid-timber build, the design strategy utilizes a contemporary contrasting extension for a new master bedroom wing and integrated garaging.

The Transition and Spatial Logic

To manage the threshold between two different architectural styles and structural systems we created a hallway transition point, cleanly separating two forms. This layout rationalizes the circulation of the home, transforming the arrival sequence into a deliberate journey between the original structure and the new private wing.

Bush Integration and Microclimate

To connect the expanded footprint with its native surroundings, a new timber deck was integrated into the layout, and new glass doors were installed to open out onto this space.
