The terraced house is a part of six houses in the consolidated villa district, the monument zone "Villa Colony Ořechovka" built in 1920 according to the design of architect Hnilička. The proposal leaves the building in its original form, including the courtyard extension, which is conceived in a hostorizing form. The proposal then focused on finding the optimal internal arrangement and increasing the living area. The building has a new basement and is open to the garden with an English courtyard, which is loosely connected to the ground floor by terraced stone surfaces. The floors are connected by a spiral staircase that minimizes the amount of space required.

Due to the heritage zone, no unusual technologies were designed, used or installed, everything is handled by classic construction procedures. It was difficult to secure common walls during the excavations and further by the method of gradual sub-walling. However, this is also a classical method. The staircase is also specific, the steel structure of which is anchored to the perimeter walls one step at a time, and the subsequent wooden paneling is formally tightened to the zero spindle.
