TENNISFREUNDE · STRATEGIC DESIGN & COMMUNITY
A new way to belong on court.
I co-founded Tennisfreunde Berlin-Mitte with my friend Hakan Karahan. I designed the brand, spaces and member experience around one idea: a place where people come together through tennis and help shape the community themselves.

CHALLENGE
Five courts. A different kind of club.
Five courts and an ageing clubhouse became our starting point. I mapped the journeys of founders, investors, neighbours, families and children to design a welcoming, nonprofit club.
THE IDEA BEHIND IT
Bringing Marienfeld to Berlin.
I grew up in Marienfeld, a small village near Cologne with around 1,500 people at the time. We lived beside a cow pasture and the football pitch, where young and old gathered on Sundays. I wanted to bring that sense of community to Berlin.
A club’s value lies in what people do for each other. Everyone contributes what they can and meets people they might otherwise never know.
BUILDING THE CLUB
One identity. A whole experience.
I designed the identity and member experience, developing the clubhouse with Daniel Dendra of anOther Architect. Hakan Karahan, my friend and co-founder, brought the coaching expertise that made the club possible.

A shared identity for the club and its members.
A club people can recognise
I developed the logo and the club’s complete visual identity as part of the same thinking that shaped its spaces and everyday experience.

Freunde Open
Our annual club tournament at Tennisfreunde Berlin-Mitte. I designed its own logo as part of the club’s visual identity.
LIFE AT THE CLUB
More than a place to play tennis.
The key moment comes after the match: sharing a meal with the visiting team. Long tables, a shared kitchen, barbecue and generous lounge make the club everyone’s space, without a restaurant.

Club life continues beyond the baseline.
DESIGNING THE MEMBER JOURNEY
Small details. A sense of belonging.
Coaching, a private shower, then coffee on the terrace. Individual changing spaces and a child-height washbasin turn specific needs into architecture. Low-maintenance spaces leave more time for the court.







RESULT
A tennis club. A place to belong.
Today, 130 children belong to the club. Members shape our spring and summer celebrations. The veranda connects clubhouse and courts; a planned hall will extend this community into the winter.
