S+N Planung

What S+N Planung does

S+N Planungs- und Entwicklungsgesellschaft mbH is an architectural planning firm founded in 2020 and headquartered in Erlangen, Germany, operating as the centralised planning office within the Niersberger Group. The company delivers HOAI-compliant architectural services across the full LPH 1-8 lifecycle — from feasibility studies and permit planning through execution planning to construction management — with a particular emphasis on affordable housing (renovation and new construction), urban densification via timber-construction rooftop extensions (Aufstockung), and heritage/monument-protected building projects. It also serves industrial clients with technical building planning, coordinating general-planner delivery alongside the group's in-house HLSE engineering office (NWE).

The technology stack is built around conventional AEC digital tooling rather than AI: BIM (Building Information Modelling) for coordinated design, 3D laser scanning for precise existing-building documentation, and integration of Smart Metering, photovoltaic systems, E-charging infrastructure, and BHKW (combined heat and power) heating networks into residential projects. Core service lines are Beratung/Konzeption (consulting and feasibility), Planungsleistungen (comprehensive planning across residential, commercial, and industrial), Architekturplanung (classical HOAI architectural planning), and Generalplanung (general-contractor coordination across disciplines via the Niersberger ecosystem).

The business model is professional services revenue billed under HOAI fee structures on a project-by-project basis, with contract values ranging from approximately €105,000 to €12 million and project durations spanning multiple years. Customer segments are dominated by social housing companies (GEWOBAU Erlangen, CI Wohnen, Niersberger 365), with secondary exposure to municipalities and public utilities, industrial buyers (Schaeffler AG, WAZV Jessen), education (FAU), and banking (Sparkasse Erlangen). GTM is sales-led, leveraging the Niersberger Group referral network and direct enterprise engagement rather than open-market tendering. The company has no external funding, operates as a privately held GmbH, and remains wholly owned within the Niersberger corporate family.
