Marek's architectural practice has taken him to different parts of the world. His professional experience has involved divergent project approaches, different ways of working and handling commissions. In 2015 he took a chamber examination in professional practice and became a chartered member of the Slovak Chamber of Architects. The core of Marek’s experience stems from Sweden where he has worked as a senior architect at Nyréns and a project architect at Erséus arkitekter. Since December 2018 he is working as a senior architect at Tovatt Architects & Planners.

Marek's portfolio covers a variety of projects, e.g. industrial buildings, housing, public buildings and more. He likes to examine every task from different angles, extract its essence and look for its design expression.
