We build the Change.
In dynamic markets, we develop vibrant neighbourhoods, modern corporate headquarters and liveable homes. For us, these are not just properties, but opportunities for success, growth and value creation.
Always forward-looking, our development team realises its own projects as well as joint venture or service developments. In addition to new developments, we also focus on inner city redevelopments.
Through our own investment management company, we offer customised investments products for institutional investors in attractive asset classes such as residential, commercial, healthcare, light industrial and parking.
Owner-managed since 1999
We believe that when you own something, you take even more responsibility for it. Since Quantum’s foundation in 1999, the two founders have been members of the board - this guarantees our independence, enables quick decision-making processes and creates more room for ideas.
