Our mission

Customer = Nature

Most of all, we want to inspire. Show people that we can join forces. That so-called "green activists" do not have to act in conflict with business. That business can be "green." That "system" can be combined with Nature. That one can exist alongside the other. We strike a balance between our customers and the needs of sustainable development. Customer = Nature. In today’s situation, where population growth is increasing at an alarming rate, education is the only way to save Nature from economic growth, by literally expanding people's awareness.

As a company in the construction industry, we know well that a huge responsibility rests on us. We are not that different from other companies in the industry and their approach to their customers. Just as others do, we consider our clients to be of the first importance: individual approach to each, analysis, planning, executing commissioned projects to the highest possible level, and we deliver to that standard.
For us, however, something else is very important:


Most of all, we want to inspire. Show people that we can join forces. We created this company because of Her. Every project, from initial analysis, planning, to execution—at each of these stages, our company takes NATURE into account. Sustainable development is the main goal of our business, but not just that. There’s more.

At the very beginning, QUERKO envisaged the GREEN QUERKO Foundation, and it is at the center of our organization. We are a company that manages funds (money that we earn through our work) for the needs and functioning of our foundation, setting and meeting goals intended to help NATURE.

In short, we are working hard and earning money that we use in projects that help to protect Nature around the world.

So by working with us, you automatically contribute to improving the world.

Querko heeft bij ons een dakopgang en groot dakterras (70m2) gerealiseerd. Ik ben zeer tevreden over hoe alles verlopen is. We zijn altijd goed op de hoogte gehouden van vorderingen en verwachtingen. We zijn betrokken bij de keuzes die gedurende het project nog gemaakt moesten worden. En misschien wel het belangrijkste; een probleempje dat nog na de oplevering aan het licht kwam, is zonder discussie of wat dan ook, zeer netjes opgelost. Ik zou Querko hier om zeker aanraden.

Working with QUERKO was a positive experience. The organization is set up to make a difference in the world via its work—not just sustainable and ecologically advanced buildings, but positive impact on people, wildlife, and planet. Their founding mission carries over to their business relationships. The manager I worked with was kind, professional, committed, and fair. I could not have asked for a better working relationship—if you can work with them, do it. You will not regret it!
