Definitely add a rug with some pattern and texture to break up the conglomerate of dark colours both with the tiled floor and chocolate modular lounge. The rug you choose will then dictate what scatter cushions to select for your lounge. You may want to consider asking your landlord if a art hanging track can be installed this way you could hang a lovely print or artwork behind sofa. With an art track it is usually powder coated white and installed just below cornice and looks like part of the cornice. You are then given by the installer acrylic hanging wires that slot into this track making it versatile to hang either a series of smaller prints or one large one and you can change as often as you like without any damage to the walls. Your artwork can also be the basis for selecting a rug and scatters. You will be amazed how by adding the rug, scatters and artwork will give instant warmth and personality to your room. You may also want to add a coffee table too. If it is a particularly beautifully patterned rug that is a real feature think of a glass coffee table so the rug can be seen. This may also keep heaviness out of the room that is happening with dark floor dark lounge. All the best! Camille Interior Designer Australia

Ana, can you provide dimensions to help with layout. And what furniture and style you are seeking. For a master the closet space seems small. By workroom is that an office, craft, sewing, exercise?

The long wall you could put in a long bench with storage drawers under. Then art work above maybe some shelves. Short wall depends on window treatments. But prob a picture. As it is a view point

Do you mean inside the open shelves? Decorative storage boxes in coordinating colours. If you don't need the storage yet you might later so don't waste shelving you already have and don't clutter it up with impersonal 'decor' stuff. It's also easier to dust than a hodgepodge of tchotchkes.
