Building a coastal home is a special opportunity to create a sanctuary that perfectly harmonises with its natural surroundings – and the Bass Coast, Mornington Peninsula and South Gippsland regions make for an ideal setting.

Beachside living done well calls for an expert architectural and interior design approach that understands site, climate, landscape and community. At Harris Build, we are experts in crafting unique coastal homes that make the most of their locations and we work closely with our clients to realise their dream beach house designs.

Curious about coastal homes? Here's everything you should consider about coastal home designs, with a few of our exemplary projects that embody Australian coastal style.

What is coastal home design?

Coastal home design is more than just a style; it's a philosophy of living that embraces the unique environment of beachside and seaside locations. It prioritises a strong connection between indoor and outdoor spaces, allowing residents to fully immerse themselves in the coastal lifestyle. The emphasis is on creating a relaxed vibe, with airy, light-filled interiors that maximise natural light and ventilation, often featuring a breezy open-plan floor. This approach ensures the home feels integrated with its setting, fostering a serene and inviting atmosphere that captures the charm of coastal living.

Key features of modern coastal designs

Modern coastal designs are characterised by clean lines, sophisticated simplicity, and a deep appreciation for natural materials. Unlike traditional beach house aesthetics, modern coastal homes often feature a refined colour palette, moving beyond typical nautical hues to embrace a more nuanced range of blues, greens, and sandy tones, complemented by crisp whites and light timber.

Key elements of this design philosophy include:

Open-plan living spaces, specifically designed to maximise natural light.
A seamless flow between indoor and outdoor areas, creating an airy and relaxed coastal environment.

This approach results in a space that feels both contemporary and deeply connected to its natural setting, enhancing the overall coastal living experience.

The importance of location in coastal house designs

Location plays an absolutely critical role in shaping coastal house designs. Factors such as prevailing winds, sun orientation, potential for stunning views, and local climate conditions significantly influence the architectural choices, material selection and overall layout.

For instance, a home built on a cliff face will require different considerations for wind resistance and erosion compared to a house nestled in a protected cove. Thoughtful design maximizes natural light, provides shade where necessary, and creates sheltered outdoor spaces, ensuring the home functions optimally and enhances the coastal lifestyle, reflecting the unique charm of its specific beachside setting.
