The house is located east of the city’s historic center, in the row housing of Vynnychenka street. This plot, like that of the neighboring corner house (№24), belonged to the Discalced Carmelite nuns' convent, which was founded in 1642 by Jakub Sobieski, the father of Polish king Jan III Sobieski, the Ruthenian voivode and the castellan of Krakow, who had his court there. It was from his name that the hilly area between contemporary Kryvonosa, Vynnychenka, Lysenka, and Hutsulska streets was called Sobieszczyzna in the 17^th and 18^th centuries. Sobieski granted the land, located within these streets, to the convent. By the second half of the 18^th century, there was the Carmelite nuns' yard with farm buildings on the hills.

After the abolition of the convent in 1784, its estate, as well as many other estates belonging to Galician monasteries and convents abolished due to the Emperor Joseph's reform, was transferred to the fund of religious assets. In 1786 the Carmelite nuns' yard, located directly at the walls of their convent, was transferred by the Lviv Directorate of the sacral property to the possession of Jakub Walker, a Lviv cartwright. This property, together with the ground, was 5700 square cubits large. In 1802 the yard under conscription number 2 4/4 (now vul. Vynnychenka, 26) was bought from Jakub Walker by Kasper and Elżbieta Zacherl. After the death of Kasper in 1812 the estate passed to his wife Elżbieta who later divided it between her children Leopold and Dorota.

in 1865 Leopold Zacherl, a Lviv merchant, sold his property to Leopold Haberman. That same year Haberman had the old two-storied house reconstructed. On 17 October 1875 Leopold Haberman sold his property to Piotr Wajda, a member of the Lviv city council (construction department), and to his wife Honorata. The following year, Piotr Wajda began a reconstruction of the old house and commissioned Michał Fechter, a Lviv architect, to design a project; however, the project of a three-storied townhouse, approved in 1876, was not implemented. In 1879 Fechter designed a new project for Wajda, this time of a four-storied townhouse with a mezzanine, approved by the Magistrate on 29 September of the same year. First, as the site plan shows, the new townhouse's left half was being built while the old house was being dismantled. In 1880 the same architect designed a project of the other (right) half of the townhouse. Designed by Fechter in Neo-Renaissance style, the building with its magnificent architectural decoration was constructed without any changes. Its current condition corresponds to the author's project. The house was completed in the same year, and in December Wajda got the Magistrate's permission to settle it. As of that time, the house on Czarneckiego street had the number 28, but, at Wajda’s request, in 1896 it was replaced with the contemporary number 26.

Two years later the townhouse was bought from Piotr and Honorata Wajda by the Shevchenko Scientific Society. The contract of sale dated 5 August 1898 was signed on behalf of the Shevchenko Scientific Society by Dr. Yevhen Ozarkevych and Dr. Kost Levytskyi. The cost of the purchased house was 240 thousand crowns. A considerable part of the funds for the purchase of this property was granted by professor Pelekhin. Initially, the house was occupied by all institutions of the Society, including the administration, a library, a museum, editorial offices of the "Memoirs of the Shevchenko Scientific Society" and of the "Literary and Scientific Bulletin", a printshop and book stores.

In 1912 the Society carried out a reconstruction of the wing to adapt it for their printshop (architects Włodzimierz Podhorodecki, Ivan Levynskyi/Jan Lewiński). The Society rented out the house to officials.

At different times the two houses of the Shevchenko Scientific Society (nn. 24, 26) were inhabited by prominent figures of Ukrainian science, culture, and art, including Mykhailo Hrushevskyi, Ivan Franko, Lesia Ukrainka, Vasyl Stefanyk, Borys Hrinchenko, Filaret Kolessa, Mykhailo Vozniak, Kyrylo Studynskyi, Yaroslava Muzyka, Ivan Trush, Stefan Kachala and many others. Commemorative plaques, dedicated to some of them, are installed on the façades.

In the Soviet period, the house was residential.
