The house on vul. Fedorova, 12 is situated in the rear part of a parcel belonging to the eastern Rynok square quarter. The present building stands on the site of the old 17^th century townhouse owned by the family of Krauze and therefore called Krauzivska (pol. Krauzowska) in old documents. On the long parcel, the Krauze had a front townhouse (pl. Rynok, 7) and a rear one (vul. Fedorova, 12) with a courtyard, where utility wings were located. In the mid-19^th century the rear townhouse was owned by Józefa Jankowska. A 1864 construction commission informed the Magistrate that the wings were incomplete and in a very neglected condition and that there was a stable in the courtyard, which was to be dismantled. In 1875 new co-owners of the building, Józef Grunberg and Zille Katz, appealed to the building administration for permission to erect a two-storied wing in the place of the old stable and were given consent. Already in the autumn of 1876 the new wings were moved into. However, on 19 July 1893 the Magistrate convened a commission to examine the condition of the building. The commission's conclusion was as follows: to oblige the owner, merchant Rachmiel Merkel, to restore the whole townhouse, to arrange a fire-resistant roofing, to connect the building to the sewerage system and to pave the courtyard. Yet Merkel delayed fulfilling the Magistrate's requirements. Only in 1903 he commissioned a project of a three-window-axis townhouse, which partially reproduced the old one’s layout. Never starting the construction, in the summer of 1904 Rachmiel Merkel sold the townhouse to Bernard Frucht, who immediately asked the Magistrate's permission to reconstruct it and to build four-storied wings. On 25 November of that same year the new owner was given consent for adaptation works which would involve a reconstruction of the staircase, rafters and fireproof roof, as well as constructing a four-storied wing in the place of the dismantled two-storied one. Frucht, however, did not take into account these requirements and started dismantling the buildings. On 8 December 1904, when the buildings were still being dismantled, there was an article titled "Vandalism again" in the newspaper Kurjer Lwowski. Among other things, it said that the dismantled townhouse had white stone trimmings, interesting vaults in the entryway, a characteristic entrance gate and ceilings made of profiled beams. All these artistic elements were lost during the reconstruction. It was only after this article that on 9 December Bernard Frucht made a request to the administration for dismantling of the entire townhouse, which was consented. On 12 December the Grono Konserwatorskie instructed the owner to make photographs and measure drawings for the city archives.

The four-storied house was built in 1906 under a project designed by architect Artur Schleyen, who designed an additional project. The first project for the construction of the new townhouse was designed by August Bogochwalski. According to the latter's project, the new building retained some features of the previous one; in particular, it had three window axes. The construction was managed by architect Michał Fechter. The four-storied wings in the courtyard were built simultaneously with the main building and under the same project. In 1907 the building became home for the Polish J. Kiliński Society of the Handmade Youth. After the First World War the house became the property of attorney Filip Ewin. In 1930 he commissioned architect Oleksandr Pezhanskyi (Aleksander Peżański) to supervise the restoration of the building's façade. According to the Lviv Region Executive Committee's resolution number 130 dated 26 February 1980, the building was entered on the List of monuments of local significance under protection number 353.

Today the building's ground floor premises are occupied by a confectionery named Charivnyi Likhtar (The Magic Lantern).
