The building of the church is octagonal with rectangular spaces of the altar, staircase and two vestibules attached on four sides. It has a hipped top, decorated with kokoshniks, and is crowned with an onion dome and cross. The zakomars of the kokoshniks have a keel-shaped ending on all tiers except the upper one. The adjacent objects also received a keel-shaped roof. The choir loft is inside the main space above the entrance. There are administrative and utility rooms in the basement.
The project of reconstruction implies that the walls of the first level are completed in such a way that the building takes the shape of a square with a pentahedral apse protruding from the east and overlaps with pitched roofs to match the existing roofs of rectangular spaces, and only the roof of the altar apse rises above the space of the narthex and side galleries. The arched windows in the new walls are wider than the existing ones, framed by decorative pillars and have keel-shaped ends. There is a bas-relief on the altar apse in the niche from the outside.
The attached "square corners" on the western side are functionally connected to the central area of the temple by large arched openings and make up a single area for the faithful. Similar areas on the east side include the sacristy, vestry, and two entrance vestibules. The apertures of the two eastern existing walls of the octagon on the right and left of the solea widen to the doors and become the southern and northern gates of the sanctuary.
