Misko 21 is one of the representative buildings of Kaunas modernism, which was built in 1939. However, unfortunately, there is not much information concerning this building except the construction year. The structure is relatively small, with a basement and two regular floors on top. However, it also has a small attic, which is likely to be added at a later date. The main entrance is at the left axis of the building, with four windows on top. On top of the windows, there is an arch which is on the same surface as the rest of the volume. The entrance axis is gradually behind the other parts of the front facade. The transition between these surfaces was achieved by a small, rounded corner. There are also vertical threads next to these windows, which repeat between the other windows of the facade as well. Between the first and second floor windows, there are also ornaments which represent plants in vases. These ornaments are inside rectangular frames. At the corner of the front facade, on the second floor, there is a balcony with rounded edges and horizontal stripes made of plaster. There is moulding between the ground floor and the other floors of the building, which creates the impression that the structure resides on a plinth.
