Welcome to
Instone Real Estate!


Welcome to Instone Real Estate! We are the new guys, but you have already known us for years. New name, same high standards: We want our real estate to fulfill many people’s dream of their own four walls. For private (buy-to-let) and institutional investors, we develop projects that sustainably generate returns. Instone Real Estate was formed out of two respected residential developers: formart, which has many years of experience in planning and developing complex residential quarters and apartment buildings, and GRK, which focuses on the development and refurbishment of monument-protected properties. Instone Real Estate combines the professional expertise of both — we are convinced that we can do more together, for the benefit of our customers and our business partners.
