I have uploaded for you 2 versions of layout.
[b]Version 1[/b]-As you suggested the 3-d bedroom turns in a small office adjacent to living room, with 2 french doors.The wall betwen the 3-d bedroom and living goes 1.1 m left giving more space to living and decrease the hallway.
(the positioning of this wall 1.1 m left is the same on 2 versions)
The wall between the dining and kitchen goes away achieving a open plan.
Now you have an island with 4-5 bar stools more kitchen cabinets, if you want a double fridge, double sink and if you want a wine fridge. (the kitchen is the same on 2 versions)
[b]Version 2[/b]-The 3-d bedroom turns in a walking closet for master bedroom and a laundry.
Since this version have the laundry room the washing machine goes off the kitchen.
And you have space for dryer too.
The existing closet goes away increasing the small bathroom.
Rendering for (kitchen, dining and living) on 2 versions are the same, except for the office french doors that in the 2-nd version goes away.
