What Roffaa architecture does

Roffaa architecture is a privately held Dutch architecture firm founded in Rotterdam in September 2018 by Renske van der Stoep, a graduate of the Rotterdamse Academie van Bouwkunst with 20 years of prior experience at MVRDV, Inbo, Ector Hoogstad, and KCAP Architects&Planners. The firm designs residential, commercial, educational, and public space projects across the Netherlands, with a stated expertise in circular construction, bio-based materials, and climate-adaptive design. Its portfolio of 23 documented projects includes large competition-won urban developments such as De Kuil (23,000 m² with Heijmans Vastgoed), ZOHO (155,000 m² concept), and the Connector campus (30,000 m² with CBRE and ING), alongside smaller private residences and research installations.

The firm's distinguishing technical capability is material innovation: Restklezoor, an upcycled brick slip waste product first applied in the Netherlands at the Deventer Tuinen van Zandweerd project and nominated for the Brick Award 24; the Pluvert rainwater-harvesting and green-facade system developed with Blue Innovations and Citylab010; the Floating Bricks transparent facade element created from rejected brick slips and wall panels; and the HOH 3500 modular building unit. These sit alongside a curated "new materials library" of bio-based and circular inputs. Roffaa generates revenue through project-based architectural design fees, competition wins, and direct commissions from developers (Heijmans, OPEN development, Fullhouse Vastgoed), municipalities (Gemeente Rotterdam, Gemeente Den Haag), and private clients. The firm is entirely founder-owned, employs seven people, and operates from a converted former post office in Rotterdam's Middelland district.
