Adaptive Multigenerational Dwelling
This project reimagines how existing suburban homes can evolve sustainably to support changing family needs. Designed as a multigenerational residence, the home accommodates up to three self-contained dwellings, creating flexibility for extended families while adding much-needed housing diversity within an established neighbourhood.
Design Approach
The guiding principle, “to add whilst not demolishing” informed every decision. Rather than clearing the site, the project focuses on adaptive reuse – building upon what already exists.
Originally, the site contained two separate structures: a double garage at street level and a brick-and-tile, single-storey two-bedroom house set five metres higher and 10 meters back, on the main portion of the site. The design transforms these existing buildings through thoughtful, small-scale additions that minimise impact and avoid excavation.
- Garage Studio
A compact, self-contained studio was created within the existing garage roof space. The garage itself remains functional, with only minimal roof modifications required – a space-efficient and sustainable addition that makes use of existing volume. - Main Dwelling
The existing two-bedroom home was retained entirely, ensuring zero disruption to the functional ground floor and preserving its embodied energy. - Upper-Level
Dwelling
Above the existing home, a third dwelling was introduced within the roof space. With an independent external entrance and no excavation, this level forms a discrete, private home while maintaining the integrity of the original structure.
This layered approach demonstrates how housing density can increase without demolition, creating adaptable, affordable homes in established urban areas. It’s a light-touch design strategy that delivers meaningful social and environmental outcomes.
