The exploitation of potash salts in Kalush was initiated in 1867. It was then that industrial salt mining and the formation of the industrial center of Kalush began; in the period 1867-1875, workshops and an industrial town hall were built. The Joint Stock Company for the Exploitation of Potash Salt – TESP (in Polish – TESP, Spółka akcyjna eksplożywa soli potasowych) was transferred to the Poles from the Austrian authorities in 1925. The Kalush Saltworks complex (saltworks) was created in the period 1867-1938; Residential buildings on Chornovola Street, 27, 29 were intended for the residence of the company's management and engineers. The year of construction was 1922 (on the pediments of the central part of the main facades together with the TESP emblem). The Company sponsored the TESP Kalush football team; the stadium on Chornovola Street – TESP Kalush.
The complex of these residential buildings is located on one of the oldest streets in Kalush, which started from the Lviv Gates of the city and led to the salt-producing suburban village of Banya. It was the basis of the suburbs and mines for salt extraction. After the annexation of Galicia to Austria, the street became the axis of the construction of the German colony of Nowy Kalush and a potash salt mining enterprise. It has long connected the central private part of the city with the potash plant. The entire street was built during the Austrian rule and the buildings on it are authentic to the mentioned era.
A Polish bridge also existed on the street for a long time (until it was dismantled after the flood of 2008). Once the street was paved with granite cobblestones, which were torn off by excavators in 1978. Currently, the residential buildings on Chornovola Street, 27, 29, have not changed their purpose - they are inhabited by Kalush residents.
