Its technical signature combines Building Information Modeling (BIM) with specialist expertise in Holz-Hybrid (wood-hybrid) construction \u2014 starting with Wiesbaden\u2019s first wood-hybrid office building h1 and extending to the planned Holzhybrid-Hochhaus 'The Change' in Eschborn \u2014 plus KfW 40/55 and Effizienzhaus 40 energy standards, geothermal and photovoltaic systems, urban densification via Aufstockung (rooftop additions), and the proprietary 'EINFACH bauen!' concept for affordable housing.

Commercially, the firm sells professional architectural services on a project-commission basis \u2014 either as HOAI-regulated percentages of construction cost or as negotiated fixed fees \u2014 sourced through direct developer relationships, invited competitions (Wettbewerb), multi-stage tender procedures (Mehrfachbeauftragung), and public-sector investor selection processes. Clients are concentrated among German housing companies (GWW Wiesbaden, GSW Frankfurt), commercial developers (NORSK Deutschland AG, BECK|PROJEKT, FYRA, Mainzer emag), the pharmaceutical/pharma-real-estate sector (Pharmaserv/CSL Behring at Behringwerke Marburg), hotel brands (prizeotel/CDL King's Hotel, Premier Inn), municipalities (W\u00fcrzburg, Mannheim, Erfurt, Ulm, Darmstadt), and occasional non-profit/religious bodies.
