Adding an extension can completely transform a home — but success depends on design, not just size. At Walsh + Walsh Architects, we design extensions that integrate seamlessly with your existing structure, light, and flow — not just add square metres.

Start with Purpose, Not Size

The best extensions begin with understanding how you live. Circulation, natural light, and sightlines matter more than floor area. A smaller, well-designed space can outperform a larger, poorly considered one.

Respect the Original, Don’t Imitate It

We balance continuity with contrast. Some homes call for a contemporary extension that highlights the old; others require subtle integration. The key is proportion, materiality, and connection.

Light, Energy, and Comfort

Orientation and natural light define how a space feels. Rooflights, clerestory glazing, and open connections can transform a room. Every extension is also a chance to improve the home’s insulation and overall energy performance.

The Practical Layer

Good design anticipates the unseen: plumbing, electrics, drainage, heating, and structure. Early coordination avoids delays and cost overruns — and ensures a smoother build.

Why Design Matters

When proportion, light, and energy are considered together, the result is more than extra space — it’s a new way of living in your home.
