Hello.
This design is inspired by modern solutions while trying to use the space as much as possible. Using light colours such as white, light grey and yellow, you get a nice contrast and a warm ambient for living and working in the same space. The bed is separated by the library and a clear glass and which can also be a frosted glass to have more privacy when having friends around.
The kitchen is located in the same place, but after combining the dinning table and the countertop you get a smarter solution of cooking and using the space more rationally. The working space is combined with the wardrobe, using the maximum of the space.
The bathroom walls are untouched, leaving you with some minor changes in the sanitary furnitures. I hope this project is fulfilling your requirements.
Regards
