Key and Stone Property

Key + Stone Property is a proudly South Australian, family-owned business built on over 70 years of experience in the property and construction industry. Originally established as Lindenthal Group, we began by servicing the building industry across South Australia. In 1976, we took a significant step forward, relocating to Taminga Street, Regency Park, marking the start of our dedicated focus on property services. This transition expanded our expertise beyond construction to encompass every aspect of the property journey, from development to management and more. Recognising the evolving needs in the property industry, we rebranded as Key + Stone Property in 2024 – a name that reflects our mission of connecting people to properties that add value to their lives. Today, we specialise in commercial, residential and short-term accommodation, providing expert property management, sales and leasing with a considered approach.
