For over 70 years we have been proudly servicing the property and construction industry within South Australia.
Laying the foundations — where our story begins.
With roots stemming back to 1954, our legacy has been built on experience and defined by a commitment to exceeding expectations. Our story began as Lindenthal Constructions, servicing the building industry across South Australia, and later evolving into Lindenthal Group.
In 1976, Lindenthal Constructions took a significant step by relocating to Regency Park, a prominent industrial precinct in Adelaide. This move marked the beginning of our dedicated focus on property services, expanding our expertise beyond construction to encompass every aspect of the property journey.
Motivated by the desire to expand our horizons within the property industry, we envisioned a new entity that would stand uniquely on its own.
The next chapter — introducing Key and Stone Property.
Key and Stone Property represents a continuation of our legacy at Lindenthal Group. Backed by our many years of combined experience, our real estate agency was launched in 2023 and now forms part of a group of companies.
Today, we operate across commercial and residential property, while also managing short-term accommodation. As we grow, we continue to evolve — building on our heritage while embracing new opportunities in the South Australian property landscape.
Just like the keystone that integrally unites the arch of a bridge, we bring together all aspects of your property needs with an integrated approach. Our goal is to provide support and stability to help you navigate the complexities of real estate with confidence.
Whether you're looking to buy, sell, lease, or optimise your property portfolio, our property specialists are here to provide strategic guidance, innovative solutions and local market expertise to help you achieve your goals.
