With a sliding door, you can have each side different to match the style of the room it faces. Here are some ideas that, believe it or not, are done with sharpies on flat surfaces. I can envision a "fireplace" on the lounge side. On the dining room side, you could do the "double door" look, by putting half on the door, and half on the wall next to the door. So when the door is closed, it looks like a pair of doors, but when the door is slid open it looks like only one door (but it's the wall!) I added the 3rd picture just because I think it's so cool. I believe the only "real" thing in the room is the glass table/desk, and the filing cabinet.

Wow, I didn't expect so many responses, thank you so much for your time and ideas. I do know that the art is wrong but had to put something up from our last house while we settle in. I do find the fireplace a bit un-friendly and so I would consider changing the colour of it even just the border of it like one of the photos shows. I'm not keen on the small computer cabinet or the ladder shelving I have to admit. I was thinking more of putting 3 full width cherry wood shelves, bottom one being wider and desk height, changing the light fittings to down lights and maybe having a wallpaper or painted backdrop behind the shelves?? I realise I would have to get rid of or change the wallpaper on the other wall and change the curtains too. I take your point, many of you said it, about the curtains needing to fall straight, but I will need a wider pole to do that. Again many thanks, AnnaMarie ps we are in Ireland now but lived in australia for many years and that picture over the mantle is of an old aussie shed with moon light on it.

Adding width BEHIND THE BED - with a headboard (which doesn't have to be a "headboard"; it could be fabric, collection of mirrors, collection of pictures, a farm gate!, small chairs or stools) across the entire width. Matching bedside tables/bookcases/chests/ with LAMPS - useful storage for extra books, extra bedding, etc. CURTAINS always warm up a room. People will always feel colder away from home - provide an extra blanket or duvet to add to the bed. I notice there is no WARDROBE. Not really necessary for overnight guests (provide hooks on the back of the door) but useful for storing your out-of-season coats, etc. There is plenty of room behind the door. Buy one on eBay and paint it to suit your colour scheme.

Your room looks large and lovely but with an entrance at one end and a fireplace at the other can seem a bit long. Firstly take EVERYTHING out. This will show the room in the best advantage and get rid of clutter. Only put back things you absolutely love. I would put two sofas or a sofa and two chairs (they don't have to be a suite) in front of the fireplace OR get a solid coloured L shaped sofa as it seems you are orienting the room toward the TV. You could then put a nice rug under a light-feeling coffee table (maybe glass and wood to pick up your chimney breast) in the middle. This would allow you to get rid of the multiple small side tables. I would lighten up the alcoves alongside the fireplace, either paint or light wallpaper. Get a proper piece of furniture for the TV to stand on. TV stands are ugly. There's lots to choose from. Try IKEA. Take down the heavy curtains and put in Roman blinds in a print fabric you love (try to find one with at least 3 colours) and coordinate with your rug. You could then use colours in this to make/pick throws and pillows. At the end near the door you could put in a small table and your rocking chair and make it like a separate area for music or reading with a nice standing lamp. Get some inexpensive drum light shades to update the lighting and put in another standing lamp by your sofa, as mentioned above, and lower your pictures to eye height. Good luck!
