The palace of Electric Enterprises is one of the largest and most important monuments of Czech interwar functionalist architecture.The idea of the restoration was to present significant premises in authentic reconstructed form and modern, functional building, providing above-standard spaces. The project brings new techniques and technologies, indicates a way to renovation of similar interwar buildings. A breakthrough was the reconstruction of the cladding with an accent on architectural expression, but also the interiors joining authentic restoration and the details of new built-ins and functional parts. The core is the office part in the five-storey nave of the central hall lined with galleries around the perimeter. The dispositionally closed core is loosened towards the wings of the building and upwards into open layouts. The renovation includes adjoining spaces, a former exhibition galleries, business units with relation to the exterior complemented by modern parterre detail.

The buiding construction is a ferroconcrete monolithic skeleton based on concrete footings, supplemented at the last two floors by a steel skeleton. The main moments of the reconstruction associated with the partial operational conversion were complete rehabilitation of foundations formed by aluminous concrete, replacement of the perimeter claddings and filling of openings, replacement of technological systems with regard to the valid fire technology and control legislation and the creation of automatic parking stacker in considerable parts of basements. The restoration was technically complicated as historical elements were supplemented by the current architecture. Total restoration of facades involves the development and production of copies of large wooden and steel windows, construction of new glazed roofs over the original glass-concrete roofs improved the thermal-technical quality in all atriiums. The installed technologies represent shift in economics and operational efficiency.
