Managing Director

Samuel Haas

Samuel is a master carpenter who passed his master’s examination in 2017 at the top of his class.

Samuel first got to know the carpentry profession at the age of 13 through a holiday job. This laid the foundation for his later career choice – working with wood! After his apprenticeship in a traditional carpentry workshop in Baden-Württemberg, Samuel moved to Berlin in 2008. He first worked for a company in the field of renovating old buildings and gained a wide range of experience there.

In 2011, at the age of only 23, he founded Haas Bau Berlin KG. Together with his employees and Berlin-based cooperation partners, Samuel offers his satisfied private and business clients all work from a single source.

However, Samuel’s passion is still working with wood. In addition to his meticulous project management skills and his “can-do” attitude, his ingenuity also helps him to find creative and solid solutions for his clients’ unique building requirements.

In 2016, Samuel met Fabio Careddu, wood expert and furniture designer with his own company IDEANDU in Sardinia, on a construction site. After successfully developing their first few joint projects the two decided to merge their companies: IDEANDU and Haas Bau Berlin KG.

Thus, in June 2018 colobo GmbH was founded. With their combined expertise and experience and an expanded team, colobo began developing larger projects. Although initially working as general contractors, colobo GmbH soon shifted its focus to developing larger office and commercial spaces. In 2020, colobo expanded it’s furniture construction division and upcycling design projects by moving into a modern, 600 m2 workshop in Berlin-Pankow.

In 2021, Fabio decided to move back to Italy with his family and officially took a step back from the company to pursue new challenges in Sardinia. As of 2022, colobo also took a step back from offering general contractor services, and instead now focuses exclusively on being a one-stop source for interior design.
