Hello dear client.
I liked to work for your contest,because industrial style is one of the most appropriate style for one basement zone,to make cosy and relaxing atmosphere.So I follow you wish and instruction,and try to complete those area,as you started.
As you see,near storve area you have two armchair,different style and color,for warm and relaxing time near fireplace.Above is pendant lamp,handmade too.Floor lamp is below staris and near black armchar.
Sofa with poufs,oriental carpet,coffe desk in industrial style,with TV in front of them is another cosy area.Wall industrial lamp,and black board painted walls where the doors are,with wall industrial clock,handmade,maybe with darts hanged the one of the door,make for you another relax in this room.
I have an idea,to make wire front for one of shelves for book,you already have,with hinges opened.That will give this shelves more industrial look,and this hole area.
Hole stairs is painted in black,the doors too,and the front of the wardrobe maybe in yellow.To make contrast and good mod.
Lot of pillows is inevitable thing,for cosy atmosphere too.
Hope you like my proposal.
Best wishes.
