Real Estate Investments – Seizing Opportunities, Minimizing Risks
Technical due diligence provides you with a solid basis for decision-making before purchasing real estate. As part of a pre-purchase inspection, ESTATE ENGINEERS assesses the building’s structural condition, technical systems, relevant documentation, and investment needs. This allows you, as an investor, to minimize risks, identify potential early on, and secure the long-term value of your investment—transparently, independently, and competently.

Real estate profession
My name is René Sonnenberg. With my freelance company ESTATE ENGINEERS, I work as an industrial engineer specializing in construction and real estate. For many years, I have been helping builders, owners, and investors turn their ideas into reality—with clarity in the process, technical depth, and a genuine flair for economically viable solutions.
ESTATE ENGINEERS is an independent, building permit-authorized engineering firm based in Leipzig. With our long-standing partners, we specialize in construction and real estate projects in Leipzig and the Central German metropolitan region – from the initial vision to successful completion.
Whether project development, project management, or real estate transactions: I personally support you with my network – in a structured, forward-looking manner, and with a keen eye for what is feasible. I work closely with planning partners, authorities, and specialist trades to implement your project efficiently and sustainably.
Our work is not based on standard solutions, but on individualized thinking: Every project is different and deserves precisely the solution that fits it. Leipzig, Dresden, Chemnitz, Jena, Erfurt, or Halle (Saale) – I know the region, its challenges, and its opportunities.
What drives me? Projects that work. Properties that last. Space for happy people!
Together with you, we will turn your construction project or real estate project into a success story.
