The entrance elliptical pavilion of the NTM (National Technical Museum) depository area in Čelákovice is an important control point to which all information from the entire area is directed. It serves as a control room, a security control point, an administrative background for employees and a contact point for visitors of the area. The elliptical shape of the building is inspired by aerodynamics of technical objects - air and water vessels (airships, submarines). The facade is metal in combination with large-scale window glazing, designed to be able to respond to sunlight with a motorized shading system that ensures an optimal indoor climate throughout the year. The light colour of the aluminium facade surfaces also contributes to the stabilization of the indoor climate. Other elements of the current technological systems, such as above-standard solution of the perimeter shell or recuperation, are intended to move the building to a minimum operating energy requirement. Technical nature of the building is underlined in the interior by admission of concrete structures as well as all technical distributions and technological systems. The interior layout is designed according to the vertical axis of the staircase, which connects all levels and the horizontal axis of the corridor.
Within the framework of maintaining a unified architectural concept, the design of the entrance pavilion follows on already completed depositary halls from 2006, 2009, 2012 and 2023. The architectural design reflects materials used in the newly realized constructions of depository halls CD 01–04. The world of painter Kamil Lhoták, as well as the films of Karel Zeman, became inspiration for overall appearance of the area.

The entrance building is based on piles - there is a municipal waste dump in the subsoil. The construction is monolithic reinforced concrete. The facade was designed as a pre-set facade shell with a layer of thermal insulation with a ventilated air gap. The total thickness of the shell is 230 mm and it is made up of cassettes from the composite panel of the Bond type. The roof covering is made of wooden terrace slats on a base grid. The shading of aluminium windows equipped with triple glazing is provided by a system of external blinds. The rooms are ventilated by opening windows in combination with cooling units. Heating is provided by a hot water floor system. The heat source is a 19 kW condensing boiler. All low-current distributions of the depository area are introduced into the entrance building, it is also connected to the main utility networks of the area. It is also equipped with a camera and security system. All moving and handling surfaces comply with barrier-free movement.
