This is a really awkward space! What about trying to build a unit into the corner which seems to be dead space. This could house the television and other bits like dvr,amp etc. The unit could then extend out towards the door in length and in height either up to the start of the window or up to the start of the blinds. I would suggest drawers for toy storage and books above. In this way you leave the windows clear for light plus it looks like you have a pull down screen so the tv would be out of the way of that. This arrangement would also hide all those wires and cables! Ikea have some good examples of storage which you could adapt or copy, such as Besta which illustrates the extended toy storage. http://www.ikea.com/gb/en/catalog/products/S39927155/

I see a window there... good! Is it facing north or which direction is it? Are the doors & trim throughout the house all dark brown? Light doors & trim would help alot. Lighter happy paint colors, such as butter yellow or limon walls would bring a sunny warm fresh feel to the room. Try some punchy colored feature walls as shown in Manon's above photo (thanks Manon). Get new furniture & some fun colored art & accessories, everything's looking very dated. Better lighting & a tall floor lamp that spreads light across the ceiling or corner. Lighter drapes (with grommets) down to the floor would help OR Roman shades or 2" faux wood blinds covering just the window would modernize the space and give you more wall space. New flooring in updated colors such as white-washed gray driftwood. Designate areas or stations in the room for different activities, such as floor games in one corner with colorful interlocking foam floor mats, comfie seating (bean-bag chairs) for movies in another area, table & chairs for table activities (coloring/puzzles/games/crafts), etc. Are your children boys or girls? That'll make a difference in what you choose and how you put it all together.

Your space is quite roomy at almost 23 feet by 16 feet 5 inches. It would help us to see all four walls. Is this going to be an area where you will eat as well as watch TV? I would put in some recessed lighting: (I like the idea of painting the ceiling a light blue or yellow.) You need to have table lamps and or floor lamps as well. If those are light fixtures on the beam, I would remove them and repair the beam. Would you husband be open to staining the beams darker? Something like this: A fireplace mantel like the one in the Crisp photo would finish off the fireplace. With yellow and cream, you could go with warm colors, browns reds and oranges or blues and green.

Thank you all so much many of you suggested darkening the ceiling and leaving the beams the way it is to avoid too much work. What color did you guys had in mind?? isn't a lighter color suppose to open the room? Talianko and Hyde Evans and Shauna? ( I preferably will love a rustic lighter wood look, and the beams but does sound like a mission to get it done as sanding varnish on the ceiling might take me forever but if I get brave enough I might do it Sstar. Brio I do so want those curtains gone they are shocking :)you haven't seen the outdated blue couch yet... but I have to decide in the colors of the walls first :) I am inclined to have a rustic look for furniture... more like farm style and I also like wash off colors...my next vibrant color that i want to add is yolk yellow ( don't roll your eyes that will be in a cushions or a vase a picture) I am very impressed with all your answers and thank you all so much for taking the time to help a girl out :)
