Interview Florian Schmidhuber

OSA has designed an elegant, timeless office building for the Deutsche Finance Group in Munich's Westend district. The neighbourhood, close to the adjacent Westpark, is undergoing constant change. This led to the plan to build a forward-looking office building surrounded by greenery.

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!
