Custom Kitchen Additions in Brisbane

The kitchen is the heart of the home—and one of the best places to invest in added space and style. Whether you need a larger layout for cooking, entertaining, or simply moving around more freely, we design kitchens that reflect how you live. From luxury islands and walk-in pantries to open-concept layouts that connect to dining and living areas, every inch is built with your lifestyle in mind.

We take care of everything—from custom cabinetry and plumbing to lighting, ventilation, and high-end finishes. Let’s create a kitchen that’s as beautiful as it is functional.

Stylish Bathroom Additions in Brisbane

Adding a bathroom improves your home’s comfort and flow—and can dramatically increase its value. Whether you’re expanding your primary suite, building a guest bath, or adding a convenient powder room near living spaces, we design bathrooms that combine modern convenience with timeless style.

Expect spa-like features, smart layouts, premium materials, and efficient plumbing—all executed with precision and care. We tailor every bathroom addition to your home’s existing style, ensuring it feels like it was always meant to be there.

Sunroom Additions in Brisbane

Brisbane’s coastal hills and sunshine make it the perfect place to enjoy a light-filled sunroom. Whether you’re sipping coffee with a view, creating a tranquil reading nook, or hosting family and friends, our custom sunrooms bring the outdoors in—all year long.

We build enclosed patios and sunrooms that are energy-efficient, beautifully integrated, and filled with natural light. These spaces feel open, warm, and peaceful—just like Brisbane itself.

Functional Room Additions in Brisbane

Need an extra bedroom, a home office, or a space that adapts to your life? We’ve got you covered. Our room additions are designed with purpose, comfort, and flow in mind. Whether you’re building out a quiet workspace or a flexible guest suite, we ensure the new space feels cohesive with the rest of your home—down to the smallest design detail.

Our team works closely with you to understand your goals and deliver a solution that enhances both livability and resale value.

Second Story Additions in Brisbane

Maximize your space without sacrificing your backyard. A second-story addition is the ideal way to expand your Brisbane home vertically—adding bedrooms, bathrooms, or even a full upper-level retreat.

We manage every part of the process, from structural engineering and permitting to design integration and final finishes. And with Brisbane’s hillside views and charming neighborhoods, your new second level can offer both function and breathtaking perspective.
