Prior to intervention, the house was assessed against:

• Architectural significance (early courtyard planning in Australia)
• Technical significance (Knitlock precast concrete block system)
• Landscape significance (integration of dwelling and bush garden setting)
• Spatial significance (integrity of original planning)

Despite incremental alterations and periods of neglect, the primary spatial order and much original fabric remained intact.

This level of integrity directly informed the conservation strategy.

The conservation methodology prioritised:

1. Repair before replacement
2. Removal of unsympathetic alterations
3. Minimal intervention to significant fabric
4. Integration of new services within non-heritage elements where possible

Working in collaboration with architect Christopher Hewson, all interventions were guided by physical evidence within the building rather than conjecture.

Structural instability in sections of the original fabric required carefully engineered stabilisation works. Integration of contemporary services — particularly within curved masonry — demanded bespoke detailing to avoid visual or spatial disruption.

The project demonstrates conservation as both a technical and architectural discipline — requiring investigative rigour and restraint.

The Griffin courtyard plan proved highly resilient. The organisation of rooms around light, air, and garden allowed contemporary living to be accommodated with minimal reconfiguration.

New services were largely confined to later additions and secondary fabric. This approach preserved the clarity of the original architectural intent.

The project reinforces the durability of early climate-responsive domestic planning.

Interior works focused on fabric retention and reinstatement:

• Fireplaces restored to operation
• Original joinery repaired and extended
• Timber floors refinished
• Discreet heating introduced with minimal visual impact

Colour and material selections were intentionally restrained to support continuity rather than contrast.

The original landscape concept — embedding the house within an Australian bush setting — had been compromised over time, including the insertion of a swimming pool.

In collaboration with Sam Cox Landscape:

• The pool was repurposed as a concealed water tank
• Indigenous planting was reinstated
• Visual and ecological relationships between house and garden were restored

Landscape works were treated as integral to architectural conservation rather than decorative intervention.

The completed works restore legibility to the Griffin design while enabling contemporary inhabitation.

The house now operates as a living heritage building — conserved, stabilised, and adapted without stylistic overlay or architectural competition.
