WONDERING WHERE TO START?
The name says it all — Glenhaven really is a haven. Tucked away in Sydney's Hills District, this prestigious semi-rural suburb is known for its large, beautifully kept homes on generous blocks, its abundance of flora and fauna, and a quiet, country village feel that's rare to find this close to the city. It's a suburb where people put down deep roots — once families find their way here, they rarely leave. With properties sitting on some of the most spacious land in the Hills District, there's often real opportunity to make the most of what you have with a well-designed granny flat. Whether you're looking to create a comfortable, independent space for ageing parents, a private retreat for adult children, a dedicated home office set well away from the main house, or a quality rental that complements your property — we'll design and build something that sits beautifully in Glenhaven and adds genuine, lasting value to your home.
