HOH Architects is an architectural firm established in Amsterdam that designs and produces at all scale levels of the built environment, varying from curtains and furniture to residential buildings and urban plans in the Netherlands and abroad. For each project, the existing situation is seen as a source of inspiration and working with what is there, with who there are and with the resources available is key in any project, regardless of scale.
Every design and construction process as an opportunity to discover the collective intelligence and creativity of all involved, thereby revealing the unique qualities of each project. Each project is a spatial integration of apparently conflicting interests, ambitions and requirements. The result is a design with autonomous spatial qualities that transcends the initial question or assignment.
HOH is actively involved in academic education, research and publications. We see the academic world as a parallel reality of practice, a testing ground for new ideas, techniques, insights and talent. Practice and theory, reality and dream are indivisible parts of each other.
HOH is founded by Freyke Hartemink, Jarrik Ouburg and Carsten Hilgendorf in 2017. Since 2023 HOH Architects is led by Freyke Hartemink and Jarrik Ouburg. Both partners have gained broad international experience at renowned architectural firms in Switzerland, Belgium, Japan and the Netherlands. By working in an international context, they have experienced that the same task can be viewed in different ways, which means that they have a broad frame of reference.

HOH does not distinguish between scale levels or disciplines. Architecture cannot exist without urban planning and landscape design and vice versa. On all scales, the disciplines influence each other. Spatial quality runs across scales and disciplines and is a consequence of the history of the place and the spirit of the place. That spirit is in the users and the location. A self-evident built environment provides peace and space when these disciplines overlap and give each other space.
Our approach is pragmatic and intuitive. We research by design and design by research.

FREYKE HARTEMINK (1975, NL) is a Dutch architect and textile designer. She studied architecture at the Eidgenössische Technische Hochschule in Zurich, Switzerland, and graduated from the Delft University of Technology in 2001. From 2001 to 2003 she was an independent researcher in Japan, at the University of Tokyo, and later worked as an architect at the office of Kengo Kuma & Associates, also in Tokyo.

Since returning to the Netherlands in 2004, she has been an architect within the office of Wiel Arets Architects, and established FreyH Studio in 2011; both are located in Amsterdam.

The contrasts and resemblances experienced while living in Japanese and Swiss cultures prompted her pursuance of mastering the ways in which design inhabits all scales. The two cultures are unified in their extremes of dealing with beauty and order.

Highlights of her oeuvre are the E’ Tower housing in Eindhoven, and the Ijhal project within Amsterdam’s Centraal Station; both are located in the Netherlands.


JARRIK OUBURG (1975, NL) studied architecture at the Delft University of Technology, the Netherlands, and the Eidgenössische Technische Hochschule Zürich, Switzerland.

He was a researcher at the Tokyo Institute of Technology and worked with Architecten Cie in Amsterdam, E2A in Zürich, Toyo Ito in Tokyo and Xaveer de Geyter Architecten in Brussels prior to starting his own practice OJO – Office Jarrik Ouburg in 2008.
He was visiting professor at the TU Delft and the Design Academy in Eindhoven. From 2012 until 2016 he headed the architecture department at the Academy of Architecture in Amsterdam where he is currently teaching and working on a research and publication called ‘Tabula Scripta’. Jarrik Ouburg regularly gives lectures and workshops at various Universities and Institutes.
