At KOLEN, we are proud of our role in the sustainable transformation of the Crystal House, located in the historic Lijnbaan ensemble in Rotterdam. Although the building is not a protected monument, it is undergoing a complete metamorphosis focused on transparency, accessibility, and a vibrant program.

For this project, we supplied and installed high-quality natural stone. Our natural stone plays a crucial role in the updated design of Crystal House, contributing to the building's modern and sustainable appearance. Thanks to our natural stone, the building now features a fresh and inviting public space, further enhancing Rotterdam's urban renewal.
