The following is the project for the interior of the Saint Alexander Nevsky Cathedral of the Holy Myrrhbearers Convent in Babruysk. Its neoclassical style is modeled after the main cathedral of the Alexander Nevsky Lavra in St. Petersburg. It takes into account all the functional features of the Orthodox liturgy. The design reflects military and patriotic Orthodox themes.

The area of the church at the zero mark is 342 square meters. The nave for the congregation is 229.1 square meters, the sanctuary is 118.9 square meters. The narthex with stairs and the church kiosk is 48.67 square meters.

The altar barrier is a metal framework covered with natural stone. Natural stone can be partially replaced with fiber-reinforced concrete. The central quarter-sphere can be made of it. The fiber-reinforced concrete is covered with a decoration made of natural stone.

The capitals of the pilasters and some other decorative elements are covered with gold leaf or gold paint. In the project, these elements are shown in yellow-gold color. The project does not include the design of the icons for the iconostasis or the icon cases.
On the iconostasis, in addition to stone, there is a quartz agglomerate based on natural stone. It is used for facing curved surfaces, deacon doors and some other elements. In the project, these elements are shown in terracotta color. Elements on which gold is applied can be made of wood, gypsum or fiber-reinforced concrete.

On the reverse side of all iconostases, there are cornices for the curtains of the Royal doors. The lamps are also attached to the reverse side. During construction, electrical wiring must be made within the frame of the iconostasis.
The walls below are covered with decorative carved stone panels. In the places where radiators are installed, the project provides for panels with a mesh to pass warm air. Built-in icon cases are designed between the windows. The linings and icon cases are supposed to be made in stone.
All wall-adjacent pilasters can be made in fiber-reinforced concrete. It can be replaced by other non-combustible composite material. Two full-fledged columns in the sanctuary and under the choir loft do not carry a load. They serve a decorative function. These columns can also be made of a composite material imitating natural stone.

The floors are supposed to be made in natural stone with inserts of brass elements. The stone can be replaced with porcelain stoneware. The elements can be carved with water cutting technique. The walls are covered with decorative plaster.
Decorative moldings, cornices, pendentives under the tholobate, ceilings (including the beamed ceiling under the choir loft and on all vaults) are made of composite material by molding and casting. The caissons themselves can be made of aquapanel. Everything is mounted on a metal frame.

The conch and the dome are made of moisture-resistant gypsum-fiber sheet on a metal frame. The decoration of window and door framing is also made of composite material imitating natural stone.
The project includes a layout of electrical appliances (sockets, switches, lamps). Individually manufactured lamps (chandelier, corona lucis, sconces) were developed separately. Part of fixtures are factory-made, for example the spotlights giving diffused light.
All liturgical furniture is to be custom-made. There are altars, prothesis altars, tables, synthronon, benches and other objects are designed. These items are tinted or painted. Carvings and other 3D decoration on white furniture is patinated with gold.
External doors are made of metal. Exterior lining is three-dimensional decoration (forming and casting technique) with patination. Inside - wood (panels with carvings). Doors must be insulated. Internal doors are made of carved wood. Transoms are made of double-glazed windows, decorated with patinated metal grille.
