A parents’ retreat is more than just a larger bedroom. It’s a private sanctuary within your home—a space designed for comfort, privacy and relaxation.

For homeowners who love their location but need more space, a first-floor addition can be the perfect way to create that retreat without sacrificing valuable backyard space.

Building for Accessibility: Creating a Home That Works for Everyone

Creating beautiful, functional spaces that give you more freedom to live comfortably, now and into the future.

The way Sydney families live is changing.

With rising property prices, increasing living costs and evolving family needs, more homeowners are choosing multigenerational living — creating homes where grandparents, parents, children and extended family can live together comfortably.

At Add-Style, we’re seeing more families looking for home designs that provide both connection and independence. A successful multigenerational home isn’t simply about adding extra bedrooms. It’s about creating flexible spaces that work for everyone, now and into the future.

How much does a first floor addition cost?

For many Sydney homes, a complete first-floor addition may range from approximately $350,000 to $650,000+, depending on factors such as the size of the addition, finishes, structural requirements, and overall complexity.

Every home is unique, which is why an accurate estimate requires a detailed assessment of your property, your goals, and the opportunities available within your existing home.
