The chapel has an elongated rectangular shape, including a narthex and a prayer room. Above the narthex was a bell tower, of which part of the octagon remains in extremely poor condition. The walls of the chapel are made of logs, hewn in a bowl shape, and are covered outside with boards painted in ochre color. Inside, the log structure is smoothed. The chapel has three main windows: two are symmetrically located in the prayer room, and one is in the narthex on the southern side. Wrought iron grilles are installed on the windows of the prayer room. The window frame of the window on the southern wall has survived. The entrance to the chapel is located on the northern side. Fragments of the railing and three posts remain from the porch, one of which has decorative processing. In the prayer room, protrusions from the logs are visible on the longitudinal walls. Traces of the original smaller windows and door logs have been preserved. Between the prayer room and the narthex, a door with tenons has survived, along with its bases and a fragment of a lock. The roof and ceiling have not survived, but a fragment of a cross, presumably from the bell tower, remains.

In 2018, during an expedition of the "Common Cause" project, the following work was carried out at the Chapel of the Holy Trinity in the village of Matchezero: clearing debris inside the chapel, leveling the geometry of the log structures and ensuring their ventilation, dismantling and marking the emergency octagon of the bell tower, as well as constructing a conservation roof over the entire chapel.

Regular inspections of the conservation roof are necessary to prevent leaks, to assemble the marked octagon under the roof inside the chapel, to develop a restoration project, and to carry out the restoration work.
