About Us

STA is a studio based in Zagreb / Bangkok founded by Petra Tikulin and Asrin Sanguanwongwan. We provide architectural as well as interior design services and are currently teaching a course in Design Methodology at NABA (Nuova Accademia Di Belle Arti di Milano).


Petra is a Croatian born architect who spent most of her professional life moving between Croatia and Italy. From 2012-2017 she gained experience mostly in hospitality architecture/interior design working for Scott Brownrigg. In 2017 she moved to Milan to work on various exhibition design projects as a freelance architect.


Asrin is an architect originally from Bangkok, Thailand. From 2013-2018 he worked at All(Zone), an architectural practice based in Bangkok. In 2019 he moved to Italy (Milan) where he achieved a master degree in Architecture at Politecnico di Milano.


Petra and Asrin met in 2017, during a collective exhibition in Triennale di Milano (999 questions on contemporary living). At the beginning of 2019, they joined experiences and founded STA.


Currently the studio is developing different projects in Croatia and Thailand.
