The building that now houses the museum “Kamianytsia of the Kyiv Voit (Mayor)” was constructed after 1695, during a period of active stone construction in Kyiv. It was built at the expense of Kyiv Voit (mayor) Ivan Danylovych Bykovskyi.

Originally designed as a residential house, it functioned for much of its history as a charitable institution. After renovation works in the 18th century, the building was transferred to one of Kyiv’s craft guilds. At that time, guilds engaged in various charitable and social activities — providing aid to their disabled members, widows, and orphans, safeguarding property interests, and serving as guarantors in charitable and trustee matters. By the second half of the 18th century, the house had lost its status as a private residence, and the descendants of Voit Bykovskyi sold their Podil properties to the Kyiv Magistrate.

The building was originally two storeys high, L-shaped in plan, with a basement and two round, tower-like corner sections. All interiors were covered with vaulted ceilings. In 1750, a two-storey annex was added; open arcades were built between the towers and on the southern entrance risalit. The variety of façades gives the structure a particularly picturesque appearance.

The northern façade features a two-tier, three-span arched loggia, with massive piers on the ground floor and columns of a simplified composite order on the upper level.

The building was constructed in the Baroque style and stands as one of the most expressive examples of 17th–18th-century civic architecture in Kyiv, reflecting both residential and charitable functions within the city’s historical and social fabric.
