Viador Átrium Group

Viador Átrium Group

Viador Átrium Group was founded in 2008 in Budapest, since then the company went through remarkable changes. The organisation not only started and survived, but also expanded during the economic crisis between 2008 and 2012. Initially our projects’ scope consisted of redesigning interior spaces of commercial buildings. Throughout the years, our scale of delivery developed to multi-storey buildings. Each of our projects’ performance brought in more inquiries and/or orders from strategic clients - given our approach towards design and planning. In the 2010s, we launched our unique service in the Hungarian market: we assign project managers to our partners, who are responsible for the framework of delivery, communication and deadlines of the construction projects. In the following years, we established our technical supervision branch and began providing mechanical and fire safety design services.  Despite broadening of our services in the past decade, the majority of our colleagues at Viador Átrium are still architects.

We believe that the key to our success is our diversity in terms of expertise among the different fields of design and construction. We are able to utilize the know-how gathered by the team members representing various professional aspects.

We are a member of a European network for architects; last year we delivered several projects with an English partner. We are certain that strategic cooperation could make a change, as in our organisation, as with companies delivering diverse services both in Hungary and in Europe.

Our Motto:
We are a community company
committed to maximum design impact;
sharing knowledge and experience;
delivering complex solutions.

Our main roles and duties:
As project managers: we design the framework of the project;
As architects and engineers: we create ultimate design tailored to the project;
As technical supervisors: we follow the implementation of the design.
