This is floorplan of one old house, but I would tell with lot of potential. It is fairly sized, it has windows on all sides and entrance door could be repositioned. Even supporting walls are well positioned.
living, dining and kitchen 22,4 m2
bathroom 6,5 m2
bedroom 14,0 m2
kids room 10,5 m2
kids room 17,8 m2
hallway 11,8 m2
total 83,0 m2
MODIFIED FLOORPLAN
Here it is.
I think I got the most out of it- question is if could be possible to do these modifications, but should not be an issue. Supporting walls are untouched, but facilites are repositioned- which can be significant expense. Hallway is not ideal since is needed to go through whole house to get to living room which is not so convenient, especially if you have guests, but I tried to make it better with interesting detail.
Additional rooms are work space and additional bathroom, all bedrooms are in sleeping part of house and are relatively close to bathroom.
Of course, desing be at your wish. There is enough space for jackets, shoes, washing machine, drying machine and next to them narrow part for laundry baskets, above you can place heater or something like that.
