The transformation from guesthouse to grand hotel was carried out during ongoing operations as a luxurious boutique hotel. To ensure future profitability, the room count was increased from 99 to 112. We found space for these new rooms by repurposing former offices of the BKA (federal criminal police), converting salons originally linked to the suites, and utilizing the area freed up by downsizing the state reception kitchen. Fear of terrorist attacks meant there were hardly any emergency escape routes in the hotel, so we developed a completely new concept for fire safety and building security. The modernization also included making some rooms barrier-free, upgrading building systems and HVAC to current sustainability standards, and expanding the fitness/spa area, originally designed for just one state guest at a time, into a true luxury hotel amenity. Many furnishings, antiques, paintings, and sculptures are on loan from federal states. They were refurbished and integrated into the new interior design of the halls and lounges. With its own civil registry office and a small pilgrimage chapel, the Petersberg has even become a sought-after wedding venue. The renovated rotunda hosts a varied cultural program of concerts and exhibitions that appeal to a broad audience beyond conferences and congress attendees – continuously reigniting interest in the Petersberg.

The new, unique blend of luxury and approachability became apparent in the spring of 2016 when our modernized beer garden opened. Situated on the Rhine panorama terrace, 300 seats offer stunning views under characteristic lime trees. Hikers can enjoy their own snacks or purchase drinks, bratwurst, and meatloaf sandwiches from the pavilion we designed to resemble the typical dairy huts of the Siebengebirge region. On the hotel terrace, guests can indulge in coffee and cake served in style at elegantly set tables. The Steigenberger Grandhotel Petersberg welcomes a diverse range of guests. During the week, conferences and congresses form the core business, hosting UN delegations and business travelers. On weekends, visitors from Germany and abroad come to experience this iconic venue steeped in German history.
