Just Architekten GmbH

What Just Architekten GmbH does

Just Architekten GmbH is a privately held, Frankfurt am Main-based multidisciplinary architecture firm founded in 2002 and reorganized under sole ownership of Managing Director Malte Just in 2021. The firm delivers full-scope architectural services across all nine German HOAI work stages (Leistungsphasen 1–9), organized around three practice pillars: 'Bauen im Bestand' (sustainable retrofit of existing buildings), 'Arbeitswelten' (corporate interior design and tenant fit-out), and 'Lebenswelten' (urban and public space design). Approximately 25 professionals including four Managing Directors execute commissions across scales from small tenant fit-outs to flagship projects such as the 25,000 m², 160-meter WestendGate revitalization for RFR Management and the award-winning Haltestelle Offenbach bus stop for Stadt Offenbach.

The firm's underlying capability mix centers on heritage-compliant retrofit, climate-adaptive urban design, and design-led interior fit-out for enterprise tenants. Differentiated technical components include the VERD° modular urban greening system (co-developed with OMC°C, Bollinger+Grohmann, and Stefan Diez), the CARLO installation for World Design Capital Frankfurt RheinMain 2026, the 'folded landscape' approach to transit infrastructure (U5 station Glauburgstraße), and formal heritage conservation certification held by Managing Director Benedikt Völker. Computational and parametric design workflows are led by a dedicated specialist, and circular construction partnerships with Concular and Lindner/CircleNow support lifecycle-oriented retrofit delivery.

The revenue model is fee-for-service under the German HOAI architects' fee ordinance, billed per project on multi-year contract cycles. Projects are secured through open competitions (e.g., VGF U5, Rodenbach RoBBe), invited tenders, and direct repeat commissions from enterprise clients in financial services (Allianz, PIMCO, Robeco, Seven Invest, RFR), creative industries (McCann), industrial and technology (BASF, Bilfinger, Fraunhofer IIS), cultural institutions (Senckenberg, Vitra), and municipal governments (Stadt Offenbach, VGF). The go-to-market motion is reputation- and award-driven, leveraging consistent recognition from the German Design Council (German Design Award, Iconic Awards), DAM Prize, arch daily, and Best Workspaces, supported by the proprietary 'Just think' thought-leadership platform.
