We had an opportunity to participate in transformation of the legendary Smyk buidling in Warsaw. The famous department store will be a premium class office building and a commercial space. The change of use of the building posed a question about the visual impact the prior construction may have on the office interior. However, the virtual walkthrough proved it will not substantially affect the new interior office design. The biggest challenge in this project was the situation on the outside. The building itself is situated in a highly dense city center. Nonetheless, we were able to recreate a realistic view from the window for the virtual walkthrough using just photographs taken from the floors of the existing building structure.
