A new fiberglass or wood door with lots more glass in the panel. It will brighten that hallway up considerably.If you are concerned about security, use a door with glass and a decorative grill on the exterior. www.glass craft.net.

I have a pair of leather sofa. Our new living room needs some ideas. There is a big window. And the room is big too. I have a black coffee table as well. the cushion of the sofa are beige colour with grey stipe. What colour should we paint in the living room? what colour of the tiles should be?

A combination of Offwhite, Beige Upholstery and dark shades of wood would look good. Provided you keep the wood minimal . The floor can also be a similar shade of wood .

Paint the walls and ceiling in offwhite shades with only the feature wall grey
