An elevated view in Sofia, Bulgaria, captures a multi-story building under active construction

An elevated view in Sofia, Bulgaria, captures a multi-story building under active construction. The structure features a reinforced concrete frame with sections of red brick infill walls. Numerous window openings are present across multiple levels; some contain installed dark-framed, multi-pane glass windows sealed with yellow expansion foam, while others remain empty apertures within the brickwork. Bare tree branches are reflected in the installed glass panes. Grey concrete slabs delineate the floors. Visible temporary elements include wooden planks used as scaffolding or supports, and orange pipes on the upper levels. A thick black cable extends diagonally from the upper left downwards across the building's facade. No individuals are visible. In the lower left foreground, a deciduous tree with white blossoms is present, indicating spring, alongside darker green coniferous trees in the lower right foreground.
