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.

While a lot can change in over 25 years. Our values stand strong. We have always relied on trusted relationships, big visions and the courage to be different.

Better together.

Trust, respect and cohesion characterise our work both internally and externally. Because trusted relationships are the foundation of our culture. And the foundation for shared success.

Explore new.

We don't just allow change, we drive it. Because we are curious. Because we value innovation and evolution. And because we have the courage to be different.

See clearly.

We see the big picture. And recognise the essential in the complex. This makes it easy for us to run our core business with the utmost care.

Think big.

We are driven by big visions. With our expertise and enthusiasmwe are constantly finding new ways to realise them.

Take the Lead.

As pioneers, we want to inspire. This means taking responsibility and working hard to achieve sustainable results for society as well as the environment.
