The one-story, L-shaped building was built in 1910 in the Art Nouveau style with an asymmetrical composition of the facades. The house belonged to a wealthy landowner, a member of the Poltava City Duma, Konstantyn Neviant (1859 - ?). In 1909, he asked the Duma to allocate him a share of land for the construction of a house on Spaska Square, but on the condition that "the facade of the house correspond to the place". During the laying of the foundation, underground passages were discovered in the direction of the Holy Dormition Cathedral and the Church of the Savior.
Lev Vainhort, the former chief architect of Poltava, drew attention to the professionalism of the architect who designed the building: "Why does the side of the house facing the Savior's Church have three projections? Because if the architect who planned this house had made an ordinary corner here, it would have turned out to be extremely sharp, spoiling the overall appearance and disrupting the interior of the entire house. But by making three ledges, the architect got out of the predicament. Besides, when the sun went down, there was always light in the side rooms." The building is fully consistent with the character of the historic buildings on Sobornosti Street.
In Soviet times, the house was nationalized and used as a residential building. During 1928-1939, the People's Artist of Ukraine Yevhen Trehub (1920-1984) lived and worked there.
The building was severely damaged during the WW II, and after restoration, the original finish and the roof of a complex shape were lost.
In the 1970s, part of the building was occupied by the Poltava Regional Council for Tourism and Excursions. The building now houses the Shevchenkivskyi Civil Registration Department in Poltava of the Eastern Interregional Department of the Ministry of Justice.
Neviant's mansion is a newly discovered cultural heritage site, a historical and architectural monument of local significance.
