I changed partitions completely on the lower floor, you will see demolition plans in the drive. changed staircase also. There are 3 bedrooms for guests as it was required, There is kitchen with storage room and bathroom, big garage for 2 cars, large living room with dining space, in the circle I did entertainment room, (putted table of tennis and billiard as there is no any daylight.) and there is home office/study room next to the circle area.

On the upper floor I didn't touched partition walls, only removed 2 exterior walls and placed glass facade there. I have placed furniture in all spaces, including terraces. On the circle terrace I did metal structure which has smooth shape and I think it is looking good with existing building. ON this structure they can grow ivy plant which will make some shadows under the sunny days. I didn't wanted to cover it completely because of interior spaces there. By this way desirable amount of day light will be in to the living room. In central space I did relaxing zone with soft furniture. This space can be multi functional. Just for reference, there can be projection to the white wall and this space could be nice home cinema in case of desire of the owner.
