cubus plan

What cubus plan does

cubus plan is a Berlin-based architecture firm (GmbH) specializing in timber construction (Holzbau) and the renovation of heritage-listed buildings (Denkmalsanierung). The firm is led by two Managing Directors, Dipl.-Ing. Anna Ohlrogge and Dipl.-Ing. Maja Kastaun, and operates with a team of approximately 20 architects and planners. Its stated methodology centers on participatory planning processes, engaging clients, communities, and stakeholders through iterative co-design rather than top-down specification.

The firm's core technical capabilities lie in two demanding niches. In modern timber construction, it has extended into prefabricated modular systems through a partnership with MOD21 GmbH, exemplified by the HENN modular school project. In heritage renovation, the firm undertakes preservation and conversion works for listed buildings, with multiple commissions in the Baltic resort town of Binz. Project scope spans single-building commissions to district-scale master plans, including the INFA Quartier in Crivitz (11.4 hectares, 225 apartments). Geographic footprint covers Berlin, Brandenburg, and Mecklenburg-Vorpommern, with international activity in Ecuador anchored by the firm's role coordinating the Bienal Panamericana de Arquitectura de Quito (BAQ) since 2018 and the non-profit PASoS e.V.

Revenue is generated through professional architectural planning services priced under the HOAI (Honorarordnung für Architekten und Ingenieure) fee structure, the mandatory German fee regulation for architectural and engineering services. Customer segments include public institutions, foundations (notably Montessori Stiftung Berlin), private developers, and individual project clients, with multi-year engagement cycles typical for large-scale planning commissions. The firm has no disclosed funding, no M&A activity, and no public revenue figures; it operates as an independent GmbH.
