What plan zwei Stadtentwicklung | Stadtforschung | Kommunikation does
plan zwei Stadtentwicklung | Stadtforschung | Kommunikation is a Hannover-based urban development, urban research, and communication consultancy serving the German public sector. Founded in 2005 by Dr. Klaus Habermann-Nieße and Brigitte Nieße, the firm has been owned since 2019 by three partners — Dr. Ulrich Berding, Kirsten Klehn, and Lisa Nieße — while the original founders remain active in advisory roles. The firm operates as a GbR (partnership under civil law) with a team of approximately 13–15 employees plus interns spanning urban planning, landscape architecture, architecture, and open-space planning disciplines.
The firm's core offering is organized around three interconnected service areas: Stadtentwicklung (urban development consulting, including integrated urban development plans, preparatory investigations, framework plans, and neighborhood/urban renewal management); Stadtforschung (applied urban research on housing, public space, urban green, climate-adaptive mobility, and energetic urban renewal); and Kommunikation (citizen participation strategies, moderation, publications, and conference organization). Delivery is conducted through analog, hybrid, and online participation formats, with notable engagements including the Klimaanpassungskonzept for Berlin Tempelhof-Schöneberg, Maschpark redesign for Hannover, ISEK Oldenburg 2035, Sanierungsmanagement Göttingen, and the EU LIFE impaQt climate adaptation project spanning Berlin and Melk (Austria).
Revenue is generated exclusively through fee-for-service contracts with public sector clients, acquired via competitive public tenders, direct appointments, and long-term municipal management mandates. The firm has no disclosed consumer-facing channels, no marketplace presence, and no funding rounds or external investment — it operates as a self-funded, partner-owned professional services practice with ~20 years of operating history, recognized through polis-award and Stadt Kassel competition wins in 2025.

plan zwei Stadtentwicklung | Stadtforschung | Kommunikation product offering
Product offeringCore offering
plan zwei is an interdisciplinary consultancy delivering integrated urban development planning, applied urban research, and strategic communication services to German public sector clients. The firm produces integrated urban development concepts (ISEK), preparatory investigations, formal land-use plans (Bauleitplan), framework plans, neighborhood and urban renewal management, climate adaptation concepts (KLAK), and citizen participation processes in analog, hybrid, and online formats, supported by empirical research and conference-grade knowledge transfer.
Product overview
plan zwei is a consultancy firm offering three interconnected core service areas: Stadtentwicklung (Urban Development), Stadtforschung (Urban Research), and Kommunikation (Communication). These services are delivered through a project-based portfolio that includes integrated urban development plans, städtebauliche studies, preparatory investigations, integrated framework planning, neighborhood management, action research, expert opinions, model projects, case studies, citizen participation strategies, publication development, and conference organization. The three service strands are interdependent — research findings feed into urban development concepts, and communication strategies and participation formats are integral to both research and development projects. The portfolio projects span from integrated urban development concepts (ISEK) to climate adaptation concepts (KLAK), EU-funded LIFE projects (impaQt), and BBSR-funded research (Green Urban Labs II).
