A hotel is being built on the site of the former “ Neckarstraße 42 ” that responds to an exceptionally narrow lot and translates this into precise, elegant architecture. With a width of just 10.5 meters and a length of approximately 82 meters, the building forms a clear urban line and makes the most of the site’s constraints. 132 guest rooms in various categories are arranged along the length of the building, creating an efficient, well-lit structure. The lobby, restaurant, and accessible rooms on the ground floor open the building up to the urban space and form an inviting base. A compact circulation system and the clear zoning of the rooms intelligently address the challenge posed by the building’s narrow depth. The rhythmic facade structure and the slightly sloped window reveals lend the building a subtle dynamism and create a shifting interplay of light and shadow. Interior curtains ensure a calm exterior appearance and a soft, cozy atmosphere inside. A rooftop terrace on the top floor complements the amenities and offers guests a high-quality lounge area with a view.
