Hello client.
Reading your project and request,I try to unite you needs and posibility into one.As you are wanted,I made living space with sofa and TV zone,kitchen with dining,and bathroom with shower,all in rustic- modern style with clay accent.Some walls are in clay,others are in gray finishing,(all on discription top view).Wall behind living room is black board wall paint,and have black metal wall lamps.
Dining is high ,with bar stools....Floor in the kitchen is partly wooden and partly hexagon.I placed interesting wooden sliding doors between living and kitchen,and in the zone leading to the stairs.Bathroom is in bright ceramics,opposite of the rest interior,with glass wall and door which separate shower zone.
In living zone you have leather sofa,coffee table,TV shell,and lot of floor pillows,which can moved near fireplace when you want to make other atmpshere.Book shelves is all around.You make these shelves just wooden,or with combination of wood and metal,which is better solution.
To make more light in all interior,I extend windows size.And closed second door,and make door on the opposite side as main entrance in this living space.
