There were requests for a solid masonry and solid reinforced concrete, but I'm hearing about it now. I don't know where the demand comes from, but don't make such structures. Recently, we had to demolish a building in the style you mentioned that was built long ago. Even the excavation workers did not dare to take that risk on their own in order to demolish this 4-storey building. We did not know how it would behave during the demolition, how we could do this building in the city center without damaging the sides. So, with the help of a compressor machine, we manually lowered the two floors into itself and demolished the rest with a machine. Even some people who don't know the technical dimension of the issue see those who have finished demolishing the higher-rise building at the same time; He said, "Hand demolished the huge building in two days, you haven't destroyed a building for 15 days". From this point of view, I recommend that you stay away from such mixed (upside-down, right-left) structures. N. YILMAZ
