This is going to almost have to be an eclectic mix...which can work. I would cover the glass doors with curtains or roll-up shades/blinds for sure, on the living room side. Could be sheer or gauze type material. Or even roman shades in a patterned fabric. I would then find a very large ornate mirror to go over the fireplace. You could either distress one yourself, or probably find one that is already distressed. To be quite honest, the wallpaper you have on the fireplace wall looks like it could work as is. Not exactly sure what the color is...(bad computer monitor). Get one or two overstuffed slipcovered chairs with skirts. Get some throw pillows that are in the same color range as those to use on leather couch. Maybe a thick floral rug and one of those industrial bin carts for a coffee table. Go antiquing and junk store shopping...find old flower vases or ornate silver pitchers and fill them with flowers.

Hi Richie, Have a look at this: http://www.avforums.com/threads/mixed-members-home-cinema-gallery-section-pictures-only.1051141/page-5 - 12 pages of different set-ups, most of them in rather small rooms. You could choose one room that you like most (or bits from different ones) and try to replicate it. There's also a DIY section - some guys tell you what they did step-by-step. (ex: http://www.avforums.com/threads/floating-wall-with-floating-sliding-media-unit.1820614/). And obviously, look through Houzz photos too. Good luck!!

If you are going to do this - make sure the bedrooms have plenty of wardrobe space etc - don't scrimp ! Ideally every woman wants at least double the wardrobe space she already has !! And a walk-in wardrobe / dressing room is something that would earn any developer brownie points !! So if you have the space ... Use it well !! Breakfast areas in morning sunshine work well and evening sun in the lounge is good - inside outside fireplaces can work really well and everybody needs storage for summer /winter stuff (ski /scuba /suitcases etc ) so worth adding in storage somewhere accessible (like utility room ) for that sort of gear too ! This is an awesome opportunity for you ! Have fun !!!

Where are you based? Would like to work on this project with you. Jade x
