Line: The book shelf in the room shows the use of line because the book shelf shelves are built against the wall forming a miniature tree. Our eyes are drawn to look at the book shelf tree from bottom to top and outward to the tree/bookshelf branches.
Love the double sided fireplace. Grey and white make wonderful companions in a modern open plan space. Add a little texture and pattern, soft lighting and some carefully chosen accessories, then sit back and relax .
