With a team of around 30 professionals, RITTERWALD advises clients across Europe on challenges in affordable housing, sustainability, and urban development. The firm has carved out a niche in sustainable housing, developing tools like the Certified Sustainable Housing Label and contributing to ESG reporting standards. RITTERWALD's client base includes both public and private sector entities, ranging from large housing companies managing over 100,000 units to mid-sized cooperatives and local authorities. Recent projects showcase the company's diverse portfolio. In 2020, RITTERWALD advised TATTERSALL·LORENZ in acquiring a property management mandate from Edmond de Rothschild REIM, covering 20 properties with 414,000 square meters of rentable area.

RITTERWALD's expertise extends to organizational restructuring, process optimization, and IT integration for real estate companies. The firm's pan-European approach allows it to bring insights from mature housing markets like Germany and the Netherlands to emerging ones like Ireland, where it has been active since 2018.
