Understanding the existing context

This grand Interwar Californian bungalow from the 1930’s has undergone a restoration and extension that respects its historical roots while embracing contemporary design.

As Sutherland Shire architects, we approached the project with a thorough knowledge of Cronulla’s history of development and how this heritage listed home fits into that story.

A dialogue between old and new

This understanding allowed us to develop both a sensitive yet bold approach to the renovations, separating the additions from the original home with courtyards and then linking them together with a glass walkway that creates a dialogue between the new and old whilst optimising natural light, offering a fresh aspect for the previously dark and constricted interiors.

Restoring the original fabric

Restoring and upgrading the internal structure conserved the 1930s house, preserving the original building fabric wherever possible, and new materials were selected for longevity and patina.

Period details such as mouldings and timber trims were restored or replaced, and leadlight windows replicated to maintain the character of the original home.

Light, air and separation

The new addition is contemporary and distinct from the original while being respectful and complementary.

Removing an old lean-to addition and creating two courtyards has optimised sunlight and breeze and reduced the depth of the house to aid light and ventilation.

They also provide a clear separation between the new and old.

Old and new in balance

The design philosophy applied to the project was to allow the old to be old, and the new to be unapologetically new.

In their juxtaposition, a sensitive balance is struck, creating a home that respects its significant heritage whilst at the same time embracing the aspirations of a modern beachside family home.
