About Us –
Loosen & de Graaf Investment Partners

The Loosen & de Graaf Group is an owner-managed real estate investment and project development company based in Aachen.
Our core business is the acquisition, management, and development of residential and commercial real estate projects in North Rhine-Westphalia, particularly in the Aachen, Cologne, and Düsseldorf metropolitan regions.

We focus on acquiring residential properties with development potential, ranging from 20 to 200 units. Our goal is to achieve sustainable value appreciation through modern, user-oriented living concepts—from new construction and vertical extensions to renovation and repurposing.

We have an in-depth understanding of our markets, their challenges, and their opportunities. We leverage comprehensive expertise, many years of experience, and a well-established network of top-tier partners, which is essential for the efficient execution of projects from acquisition to completion. Our independence ensures high quality standards and facilitates rapid decision-making and problem-solving.

All core tasks along the value chain—from purchasing, technical and commercial property management, and asset management to sales—are handled by our group of approximately 25 employees. Architectural and construction services are provided by a long-standing network of regional partners.

In doing so, we not only enhance the value of each property but also create tangible, sustainable added value for all stakeholders: from investors, employees, and financing partners to current and future tenants.
