Gressmann Sollner Architects

What Gressmann Sollner Architects does

greßmann söllner architekten gmbh is a Regensburg-based German architecture firm with approximately 50 interdisciplinary professionals providing full-scope architectural services across all HOAI (Honorarordnung für Architekten und Ingenieure) phases, from preliminary design through construction supervision. Founded in 1990 as Planungsgruppe DPW and rebranded to its current form in 2022 after a 2017 ownership transition, the firm is wholly owned and managed by architects Angelika Greßmann and Julian Söllner. Its practice spans five vertical segments — healthcare facilities (hospitals and clinics, including complex renovations during ongoing operations), educational institutions (primary and secondary schools), public administration buildings (town halls, Landratsamt offices), heritage conservation (monument-protected buildings), and residential development (social, student, and mixed-use housing) — with project work distributed across more than 30 Bavarian municipalities.

The firm's underlying technology consists of industry-standard architectural design and planning tools, including Nemetschek Allplan for BIM-based design, Bechmann AVA for cost and tender management, MS Project for scheduling, and BIM workflows as a general methodology. There is no proprietary technology product; the firm's competitive differentiation rests on accumulated expertise in regulated, complex project types (healthcare construction during operations, heritage preservation under monument protection, and public procurement under VgV/VOF procedures) rather than on technology.

The business model is project-based professional services revenue. Fees are structured per the German HOAI fee regulations, which scale architect compensation with construction cost and project scope, supplemented by fixed-fee arrangements on certain projects. The go-to-market motion is direct enterprise field sales combined with competitive public-sector tendering. Customer segments are exclusively institutional and enterprise — hospitals, school operators, municipal governments, and real estate developers — with no consumer-facing channel. The firm has no external investment, no subsidiaries, and operates from a single headquarters office in a heritage-protected building on the Danube in Regensburg.
