What mplusm architects does

mplusm architects is a boutique architectural practice based in Friedrichstadt, Schleswig-Holstein, Germany, founded in 2007 by Dipl.-Ing. Marcus Krause and Dipl.-Ing. Mirjam Jüchser. The firm specializes in refurbishment, redevelopment, renovation, and residential construction, with a particular focus on heritage-listed buildings, historic North Frisian townhouses (Stadthäuser), thatched-roof houses (Reetdachhäuser), and energy-efficient modernization of historic structures. Its portfolio spans private residential commissions, hospitality conversions (hotels and restaurants), public-sector buildings (kindergartens, community facilities, sports halls), and ecclesiastical heritage work (e.g. Ev. Kirche St. Christophorus). Service scope covers the full German HOAI planning phases (LPH 1-9), from initial concept through construction supervision and documentation.

The firm's underlying methodology is rooted in the founders' specialized training — Krause in heritage conservation and Altbausanierung, Jüchser in hospital construction — combined with deep local knowledge of North Frisian building typologies and close collaboration with regional craftspeople. Its intellectual approach, described as 'genius loci,' prioritizes context-sensitive design, material longevity, and integration of modern energy systems (condensing boilers, heat pumps, solar thermal, PV) while preserving historical character. Technology use is conventional: spatial drawings and conceptual design tools rather than proprietary software, AI, or digital platforms; there is no app, API, or SaaS component.

Commercially, mplusm operates as a direct-to-client professional services firm with no resellers or external distribution. Revenue is project-based, billed as a regulated percentage of construction costs under HOAI (Honorarordnung für Architekten und Ingenieure), with multi-year engagement contracts typical. The firm has no external institutional investors, parent company, or subsidiaries. Customer acquisition relies on a portfolio website (mplusmarchitects.com), regional press coverage in outlets such as Husumer Nachrichten and Monumente magazine, invited architectural competitions (e.g. 2011 first prize for Asmussen-Woldsen-Kindergarten), and direct commissions. The practice is registered with the Architekten- und Ingenieurkammer Schleswig-Holstein (Nr. 6064) and operates primarily in the North Frisia and Schleswig-Holstein region, with a stated presence extending to Mediterranean Italy.
