Better buildings, a better future! We are KOERS. The new generation of builders. Originally a Rotterdam-based family business, with four offices in and around the major cities in the Netherlands. Since our founding in 1972, we have been a family-owned company with a clear course. Builders with vision. Professionals with in-depth knowledge of real estate, a solution-oriented mindset, and a strong sense of decisiveness. We renovate, refurbish, maintain, make more sustainable, transform, and develop buildings in co-creation with our clients—fully aware of the sustainable transition the construction and real estate sector is undergoing. No unnecessary layers, no slow decision-making, but short lines of communication, familiar faces, and clear agreements. We combine smart thinking and a high level of service with skilled execution. We believe in a future-proof approach to real estate maintenance. Not merely reacting ad hoc, but maintaining in a structured, intelligent, and results-driven way. Our approach is firmly grounded in ESG principles. Through data analysis and decades of experience, we can quickly move from reactive to preventive and predictive maintenance. We take responsibility for integrated real estate maintenance and assume the role of director. We treat buildings with care, as well as their surroundings, the people connected to them, and our own employees. This means renovating and maintaining with attention to safety, minimal environmental impact, and a positive contribution to the living environment. We provide insight today and for the future, honor our commitments, and work with our clients to create a forward-looking agenda. Transparent, reliable, and predictable. No surprises—just results.
