Office Architecture/design studio

The design office of OPA (Planning and Architecture Organization) is an extension of the successful work of the bureau Arhitektura Matković.

Since its establishment, many wholesome projects for different purposes have been created in the office, and the design team has also realized many external collaborations. Generally, OPA regularly cooperates with experts from other fields, which provides the bureau with a continuous offer of detailed and coordinated project documentation. Today the office has six employees — apart from the founder Tihomil Matković, the team is comprised of Barbara Maštruko, Irena Paić-Majdić, Sonja Manestar, Matej Raič and Mislav Bobić.

Tihomil Matković was born in Zagreb in 1971. After graduating from MIOC high school (today’s XV Gymnasium) in 1990, he attended the Faculty of Architecture at the University of Zagreb, from which he graduated in 1996. He receieved the Rector’s award in 1993. He is a member of the Croatian Chamber of Architects, and from the period from 2009 to 2011 he was a part of the executive board of the Association of Architects Zagreb, as well as of the legislation board of the Croatian Chamber of Architects. During the academic year 2008/2009 he was a guest critic at the Faculty of Architecture at the Department of Architectural Designs Studio 1. He has been awarded the Drago Galić award by the Croatian Architects Association for most successful accomplishment in the area of residential architecture in 2005.



Atelier Ostrman

One of the more interesting locations in Lopašićeva Street is the art studio of the painter Tomislav Ostrman, Atelier Ostrman, where he exhibits and sells his own pieces and those of his colleagues and friends, alongside organizing small social events in this attractive workshop.

Garderoba Concept Store

With the opening of Ana Ivančić’s Garderoba, Zagreb got its first conceptual showroom for Scandinavian fashion. Garderoba is a carefully thought-out project, a room whose elements have all been designed by brilliant Croatian designers and architects, thus also adding a Croatian brand to the offer.

Slatka priča

The Slatka Priča pastry shop was started in 2013, and is currently in three places – Kranjčevićeva Street, Ivana Brlić Mažuranić Street in Zagreb’s Malešnica neighborhood, and, of course, Martićeva Street (since 2016), more precisely at the busy corner of Martićeva and Smičiklasova.


Mikrofon is a music school started in 2009, located in the charming inner courtyard of 19 Martićeva Street. Its predecessor was the Vocal Studio Maraton vocal workshop from Rijeka, and the school has since then grown from offering single singing lessons to group singing and lessons for children, as well as instrumental music lessons.

Medveščak Library

The Medveščak Library, our neighborhood’s branch of Zagreb City Libraries, encompasses three departments – adult, children’s and youth (also known as “Idi pa Vidi”, or “Come and See”). Besides normal library duties, the library also engages in setting up various exhibitions in its windows, and workshops in the rooms of the youth and children’s departments.
