It’s time to get Cosi.


Cosi Haus

is an Interior Design and Architectural firm based in Berlin, Germany.

Since our opening in 2017 we have already undertaken an impressive array of high-end residential and commercial projects.

With a desire to create immersive environments, at Cosi Haus we take a creative and multi-disciplinary approach to our many different project types.

The seamless synergy of technology, German craftsmanship and design is reflected in environments that combine innovation, custom fixtures and furniture, luxury materials and antiques in a combination of classic sensibility and contemporary style.

The team is currently just three people; Maya, Thomas, and Andreas.

Maya Ceirjc

Born in the UK, Maya’s parents moved back to Germany when she was 14 years old. It was in those early years of her life that she began to form a love for the arts, and anything creative. This was to be expected, being the daughter of a musician and a painter! She studied Principles of Design at KHB, and after graduating did a lot of travelling. After this, she settled back in Berlin where she has lived and worked ever since for various design agencies.

In 2017, Maya established Cosi Haus, with the help of investment secured through the Hilfreiche Kunst scheme, and she quickly brought her close friends Thomas and Andreas into the team as she knew their skills would be a big help.

Maya’s love of natural resources, high-quality textiles and the use of natural light, are some of the key elements that she has brought to the forefront of the Cosi Haus identity, and to date it has allowed her and the team to work on some fantastic projects in a number of European cities.
