We believe in the power of cities.

25 years and counting

OSA has been shaping the cityscape of Munich and beyond for a quarter of a century. Since its foundation by Fabian Ochs and Florian Schmidhuber in 2000, the office has established itself as a major player in the Bavarian architecture scene and has realized numerous pioneering projects. OSA celebrated its 25th anniversary with a summer party at Ampere in Munich's Muffatwerk and was attended by numerous guests from the worlds of architecture, culture and the industry. Musician Nik West provided the musical backdrop for the evening. Our thanks go to all our customers, partners and our employees who made our success possible – cheers to the next 25 years!
