The new office tower named Filadelfie became part of the large newly urbanised site surrounding Vyskočilova (street) in Prague 4 – Michle in 2010. At the same time, a revitalization of the disused space between the streets Želetavská and Baarova took place converting the site into a park. Although the Filadelfie office building is located in a relatively urbanised environment, we designed the shape to maximise the detachment from the surrounding buildings. The shape of a cross diagonally oriented to the adjacent roads allowed us to keep enough free space and approach the building’s design as if it were a detached building. The building is placed without a pedestal onto a grassed plane surrounding the Filadelfie transforming it at the same time into the before-mentioned park. The basic concept of a typical office floor is a modified letter H. The main circulation core is located in the central part of the layout from where the four office wings stretch out. The opening of the wings in the shape of a cross provides the interior with premium levels of daylighting and provides panoramic views from any place along the facade. The variability of a typical office floor’s layout allows dividing it into four independent units or occupying the whole floor by a single tenant. The staircases in the two larger wings enable inner vertical connection for a tenant occupying several tiers. A distinctively shaped volume of seventeen solely office floors transforms into six underground stories on the ground floor fully developing the available site. Thanks to the terrain morphology the first basement is partially exposed along Želetavská (street), thus establishing a portal for the building’s main entrances. Retail areas are situated on this floor. The remaining five basements accommodate a car park and building technology facilities.
