Opportunities arise when you look for them.
We deal with offices, commercial buildings, flats and retail properties every day. These are not just properties to us, but prospects for success, growth and value creation.
Always looking toward the future, our project development department is constantly implementing innovative, sustainable projects throughout Germany. To date, well over one million square metres of total space have been realised, with a focus on the highest quality and long-term value growth.
Through our own capital management company, we offer tailor-made investments for institutional investors, such as pooled and individual funds or club deals.
Owner-managed since 1999
We are certain that if you own something, you must take even more responsibility for it. That is why Quantum has been owner-managed since its foundation in 1999. Our board members are the main shareholders - this guarantees us independence from banks and corporations, enables efficient decision-making processes and creates more room for ideas.
