Principal architect Bert Bulthuis holds a Bachelor degree in Building Science and a Master degree in Architecture.

He founded Architectuurstudio Sitec BNA in The Netherlands in 1993 and Sitec Studio, a new practice to expand on his Dutch building philosophy, in Hong Kong in 2012. Collectively, he and his team have designed and realised over 200 buildings across the two architectural practices.

The main themes of Bert’s work are: building as an existential manifesto from a circular environmental perspective; and designing from a specific situation (genus loci); and from the needs of specific end users (genus humanus).

His practices’ design specialties include: Mixed use developments,  housing projects for special needs groups, environmentally-friendly buildings, housing for private clients, the redevelopment of historical buildings, museums and temples

Bert works as an architect in Hong Kong on projects in Asia and in The Netherlands on projects in Europe.

Sitec Studio uses a green and circular approach in its designs aiming to maximize circularity and to reduce CO² and the use of fossil fuels in our work. Across the various projects that we have in progress,  sustainability, biodiversity (landscape in the cityscape) and the use of non-fossil energy sources (solar energy, wind energy, warming/cooling with heat pump systems) are a priority.
