City quarter development FÜRST, Berlin

A Fresh Take on Urban Spaces

We believe in cities where work and life are in balance—sustainable, vibrant, and future-ready. To meet this ambition, we develop places that transcend their physical form. We revitalize inner-city locations with resource-conscious approaches, design new usage concepts, and create spaces that bring people together and empower businesses. Our Berlin and Munich teams guide projects end-to-end—from acquisition to leasing—shaping work and living environments that define cityscapes and secure long-term perspectives. Through our actions and creations, we generate real value.

Our values — why we build

We believe the development of city quarters is more than business. It’s responsibility to what exists — and a chance to imbue new meaning into spaces. We are driven by the belief that real estate has power: economic, social, and cultural. That requires conviction, experience, and a team united by shared belief in the future.

C
CREATIVE MINDS
We don’t just invest, develop, build, or manage. We shape. Our team combines focus with creativity, passion with rationality, ambition with realism.
E
EXPERIENCE AND EXPERTISE
With full lifecycle coverage in Germany’s top seven cities and across the value chain, we are trusted partners for tenants, providers, investors — commercial, institutional, and public. We offer complete-service expertise and a network that keeps us at the forefront.
L
LEADERSHIP AND PERFORMANCE
Strength, innovation, and creativity make us a go‑to for challenging projects. We know how to give buildings a second life — turning them into vibrant spaces, inspiring addresses, and crisis‑resilient investments. Our performance is proven by 60+ projects, over €3 billion in volume, and 60,000 sqm leased annually.
L
LOVE AND PASSION
Creation drives us. With entrepreneurial spirit, passion for exceptional properties, and curiosity for innovation. Our team thinks in values and engages partners with tailored solutions.
S
SUSTAINABLE GROWTH
The most sustainable approach is meaningful re‑development of what already exists — finding solutions for problems others call unsolvable. We create value long term — actively managed, with robust usage concepts that benefit neighborhoods, cities, and society. Our company grows sustainably: organically, steadily, securely — for partners and employees alike.
