A 1930s California Bungalow in Sydney received a modern shed-like addition that maximizes the usability of the original structure, adding plenty open-concept space and natural light. Architect Prineas designed the affordable addition as a modular structure that’s easy to build and alter for optimal flexibility, while honoring the original design of the home.

The Allen Key House comprises an original 1930s bungalow and an modern, modular addition conceived as a shed-like structure. The latter emphasizes the kitchen and entertaining areas and acts as the true heart of the home.

The design team made sure that the existing bungalow is kept in its original state. They connected the original structure and the addition with a glazed link which creates two internal courtyards and introduces more natural light into the en suite and study.

Built on an extremely tight budget, the rear addition relies on a grid system that forms double-height spaces through modular design. This system of modules allows simple reconfiguration of courtyards, light wells and stairs.
