The first design has nice features and introduced options we had not thought that allowed for the teenage bedroom to have a window and to expand when no guests around and also the use of profilit which we had not considered previously. The only concern is that that there was is not enough storage in the apartment for all our things. The second design allows for more storage while keeping the the good features provided in the first design. Overall we were not sure about the cost of moving the kitchen. Thanks.
