KR1 Berlin operates with respect for the environment and strives to create structures that are environmentally friendly. The extensive experience and orientation of KR1 Berlin towards the absolute satisfaction of the client guarantee the high quality and reliability of our projects. This is achieved through faithful adherence to all regulations set by the Greek state, excellent selection of partners, thorough material controls, and meticulous care and supervision at every phase of construction by experienced and specialized teams.

Our History
The company was founded in 2021 by Konstantinos Ratis, with almost two decades of experience in the construction industry. He previously served as a co-owner of the family business “Ratis Brothers S.A.,” which has been operating in the field since 1995, constructing high-specification buildings.
The progress of quality activities, the number of construction projects, and the recognition received contributed to the request for “Ratis Brothers S.A.” to take action beyond Greece. In 2014, the family business expanded internationally, reaching the Caribbean, the United Arab Emirates, and Europe.
