SEYSTA Architekten Stadtplaner is an architectural and urban planning office operating in Hamburg and Hannover. The firm is structured as a partnership, with Jens-Uwe Seyfarth and Christian Stahlhut as key partners. SEYSTA’s Hamburg team is led by Lutz Lütjen, supported by architects, planners, and project managers with academic backgrounds in architecture and engineering.
Founded to provide architectural and urbanistic services, SEYSTA works across residential construction, office buildings, healthcare, and social facilities. Much of their work involves both new builds and the modernization or transformation of existing structures. Their focus lies strongly on combining economic viability, ecological responsibility, and social factors, integrating these aspects into both large and small projects. Rather than specializing exclusively in high-end commissions, SEYSTA takes on projects with varied budgets, supported by an extended network of specialists, including general planning services when required.
SEYSTA’s portfolio includes a range of recently published projects. Among them are residential buildings, a glamping facility designed to reflect local cultural traditions, social housing for Lebenshilfe, modern office spaces, a fire station in Reinbek, and medical practices combining surgery and laboratory functions. The firm’s approach is marked by material selection for natural spatial qualities, barrier-free design, and advisory services on energy efficiency and sustainable construction.
With offices in Hamburg and Hannover, SEYSTA maintains a team of over a dozen professionals and relies on project-based external collaborators to address complex or interdisciplinary assignments. Their ongoing work situates them as experienced contributors to the evolving built environment in the Hamburg region.
