Kokildor is a monumental construction of the XVI century. According to the its function, it was the mausoleum-khonaqo, with the original plan: widely open the niche of the portal has semi octahedron form; axial pass from it conducts into dahlid - a lobby, it is possible to get in the central room and in two lateral corridors, from here, which unites by two rooms. By form and construction of the main facade - disclosing of the monument «the developed composition» dominates over front and on a cross-section axis. Numerous niches and niche the rectangular and pentahedral plan are entered in the decoration of this facade, the portal arch and interiors. Vaulted systems are original in Kokildor. They represent the decorative arches, domes and semi dome on the combined grid of the pendentives executed from cast ganch. The monument was created as an independent building completed in an architectural ensemble and consequently so proportions of portal are harmonious in it and various development of plafond of rooms and niches.
Originally a resting place for itinerant Sufi dervishes and other holy men, the building's design owes much to cultural links with Afghanistan, especially in the styling of its vaulted ceilings. The tall, symmetrical portico appears imposing even now: it must have made quite an impression on early visitors.
Khanaka-Mausoleum Kokildor-Ota is distinguished by its architecture and unusual planning. It should be noted that the idea of building a three-stage frontal, open facade, which was used in the complex of Sultan- Saodat, was repeated here too. Its plan was symmetrical by composition: there was a deep terrace with a main entrance and large hall with a dome in the center; on their sides, almost parallel, were placed two rooms across the corridor in a mirror composition. So, the rectangular entrance led to a central hall and lateral entrances to the joined rooms and corridors that were laterally to them. The interior is decorated with amazing patterns made of ganch. In the interior hall there are gravestones, the largest one belonged to Kokildor-Ota.
The portal of this building was typical more for the Temurid epoch (XV c.) than to the architecture of Mawarannahr in the XVI c. Archeologists suggest that it could have been redecorated in the epoch of Temurids. Probably the reconstruction of the monumental structures was carried out at the same time with the complex of Hakim at- Termizi and Sultan Saodat. It should be noted that Kokildor Ota Khanaka is one of the most signinficant monuments of Termez.
