Hi, your home looks pretty good, you have done a lot on the interiors. Coming back to the question, yes, you can add a wallpaper behind the television, go for a textured wallpaper as it will create a compliment to your television. As you have decorated with wooden elements, you can go with a bookshelf on the wall. And, there is one more thing which will be a simple addition but will look perfect and that is an antique wall clock. An antique wall clock will make your wall look great without any fuss.

The only thing that is really ugly with this bathroom is the floor tiles and old shower screen. I'm all for getting new shower screen install. Repaint the whole bathroom with tile paint and for the floor get good quality water marine grade merbau timber and put timber decking over the bathroom floor. New shower head and tap fittings if you see fit.

yvonne.. re sanding cupboards I had mine professionally sanded because they were looking worn. timber is American Oak and it really didn't lighten very much by sanding. so depending on your timber you might not achieve much. i would change a few upper cabinets with glass doors, white perspex or remove a few doors, paint the back of shelving and hang wine glasses or whetever and break the load that way. I replaced my range hood with a pull out chrome one and that in itself made a difference nt tying in with the chrome handles. see pictures. maybe you could paint the legs or reupholster the stools to white...all part of the kitchen.

I have not read all of the above. It must be tempting to render and paint the fireplace but if it is decided to work with it then maybe you can find your colour palette in the bricks. The new grey carpet will give you a fresh neutral but grey can be very cold. you might need a bit of warmth in the others colors chosen for walls or soft furnishings. If you extend the tile base in front of the fireplace that will give another opportunity to introduce more impact with the tiles. There are always lots of gorgeous tile options. I am loving some of the Moroccan looking styles.
