Description: The existing structure has one storey beneath and four above ground and has a flat roof of just one layer. The basement floor features facility rooms – laundries, drying rooms, spaces for storing prams, storage spaces, maintenance rooms, and car parking bays. From the second up to the fifth storey there are apartments.

More flats will be added - studio flats, two room flats with a built in kitchen, two room flats with a separate kitchen - in the extended section, with some featuring a terrace. In total, there will be 10 new residences. The extension and the building have been designed so that two and three apartments are accessible from a mutual stairway with a personal lift on the exterior. The project has 23 parking spaces planned, two of which will be for those with disabilities.

The ground plan of the building is rectangular, its maximum size being approximately 35 metres x 11 metres. Vertical outer walls are brick built, and window piers are of diagonally perforated bricks laid on cement-lime mortar. Internal pillars of reinforced concrete have been placed where bore holes were made in the basement. The ceilings of the separate stories are reinforced concrete panels, having been laid on external walls and reinforced concrete central girders. Twin stairways have been fitted; these are made of reinforced concrete and mounted on diagonal load-bearing walls.

According to research, the structure was originally built on concrete strip foundation. To avoid overloading the existing structural framework, the lightest building materials have been chosen for the extended section.

It will be necessary by this August to have provided all required connections, re-laid items, installed new underground utility lines, and used all heavy machinery needed. Such items must not hinder access to the road then, as Květinková Street will carry all through traffic whilst Pod Lipami Street is closed.
