Introduction

On Victoria’s Mornington Peninsula, nestled within the gentle coastal bushland of Mount Martha, Victoria Merrett Architects have reimagined the archetypal Australian beach house for the 21st century. The Mount Martha House is a contemporary interpretation of informal holiday living—a resilient, design-led residence that pays homage to mid-century beach shacks while integrating advanced sustainability measures.

More than just a coastal retreat, this residence serves as an instructive model for site-sensitive design that blends architectural history, climate-adaptive construction, and relaxed liveability. By exploring the design choices at Mount Martha House, architects, builders, and homeowners can extract relevant strategies for designing enduring, energy-efficient residences across Australia, North America, and Europe.

Residential Architecture and Historical Context

Throughout Australia’s coastal regions, the legacy of modest mid-century beach houses remains a strong cultural and architectural influence. Recognised for their open plans, unpretentious materials, and seamless integration with the outdoors, these homes captured a simple but potent vision of seaside living.

At Mount Martha, Victoria Merrett Architects have drawn richly from this lineage while introducing a modern sensibility. The final composition presents:

• An L-shaped, single-storey layout centred around a landscaped courtyard
• Timber-framed construction with weather-resistant cladding
• Deep visual and spatial connections with the site’s existing pin oak and natural terrain

This reinterpretation also draws inspiration from European summertime homes—particularly Scandinavian and Mediterranean retreat architecture—where outdoor-centred living, framed courtyards, and seasonal adaptability are inherent design strategies.

Core Design Principles

Plan and Zoning

The hallmark of the residence is its L-shaped plan, optimised for passive solar gain and outdoor living. Each arm of the L holds distinct functions: one houses private bedrooms, while the other defines a spacious, light-filled communal zone that opens up to a courtyard complete with pool and timber decks.

The zoning strategy reflects evolving family needs, offering flexibility through:

• Two main bedroom suites, each with ensuite facilities
• A guest retreat ideal for extended family or short-term visitors
• Zoning that permits privacy while encouraging spatial fluidity during social activities

This spatial logic is increasingly relevant for multi-generational and shared housing models gaining traction globally.

Connection to Outdoors

Much like the iconic porches of Cape Cod homes or the terraces of Scandinavian cottages, Mount Martha House thrives on its immersive relationship with the exterior. A network of wide operable glazing, timber decks, and planted garden beds enables:

• Cross-ventilation and natural cooling
• Visual continuity between inside and outside
• Spaces for informal dining, relaxation, and play—all crucial to coastal lifestyle

These outdoor interfaces are not auxiliary; they are essential living zones that extend the functional envelope of the home.

Materiality and Finishes

The house takes cues from its climatic and cultural environment in the material palette. Externally, iron ash timber cladding, weatherboards, and exposed white LVL rafters create a voice that feels at once resilient, light, and coastal. These materials offer:

• Low-maintenance durability suited to salt-laden air
• Textural interest and natural weathering over time
• A visual softness that corresponds with the surrounding tree canopy

Internally, the aesthetic pivots toward simplicity and tactility—employing timber veneer cabinets, stainless steel surfaces, and natural stone such as marble for benchtops. Combined with painted finishes and a restrained colour palette, the interior framework supports a relaxed but refined domestic atmosphere.

Sustainability and Engineering

Constructed with a conscious eye on long-term environmental performance, the house uses:

• A timber frame combined with a high-durability envelope
• Meticulous site orientation for passive solar heating and cooling
• High-performance insulation tailored for coastal temperature shifts
• Precision-placed operable windows that support natural cross-ventilation

These features echo worldwide practices in sustainable residential design—from North America’s Passive House movement to thermal-regulated vacation homes in northern Europe—demonstrating how region-specific objectives can align with global sustainability goals.

Summary for Architects, Builders, and Homeowners

The Mount Martha House by Victoria Merrett Architects serves as a prime example of how modern residential design can embody both climatic responsiveness and cultural resonance. Several key lessons emerge:

1. Courtyard configurations offer privacy, harness passive solar gain, and increase site engagement—ideal for tight urban lots or wide rural blocks alike.
2. Material selection should align with the local microclimate while supporting tactile, comforting interiors.
3. Passive environmental strategies—such as cross-ventilation, solar orientation, and high-performing insulation—are central to both sustainability and comfort.
4. Zoned layouts afford flexibility for changing family dynamics, making them suitable for long-term occupancy strategies.

With careful attention to site specifics, cultural references, and performance needs, architects and homeowners everywhere can translate the core principles of Mount Martha House into successful residential projects—whether on windswept headlands, forested landscapes, or suburban plots.

The Mount Martha House offers a benchmark in design that is respectful of the past, responsive to the present, and resilient for the future.
