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.

definitely use a designer - they have a much better idea of what plants will work and why, which will save you a heap of money (I have replanted 8 times due to having a poor understanding of what to put where) and when it comes to draining, paving, irrigation etc they have experience of not only how, but which products will produce what results.... Plus a good designed area looks "done" (think display home gardens/features) however self-designed always look "bitza". If you don't have the money to do the entire plan that they design, ask them to break it into stages that you can execute/upgrade over time that still looks good in its most basic form.

Cleaning the bathroom is a breeze, I have a nylon scrubber that I buy from Coles or Woolies and the cheapest shampoo I can find, after my shower I put a couple of squirts of the shampoo on the scrubber, run it from top to bottom all round my shower ( I have a large double head shower ) and over the floor then spray clean warm water from the top of the wall and let it run down the walls and glass area till the soap has gone, the shower in our 2nd bathroom doesn't have a spray so I use an empty Peters 2 litre icecream container keep filling it up with warm water and run this down the walls, hop out of the shower walk away and let it dry by itself -- once it is dry I have a perfectly streak free shower, for the bath and the vanity basins I use the same method, wipe them over with the scrubber and shampoo, flush with the warm water and leave, wipe the vanity tops, the area around the bath and window area with a damp cloth and hey presto a beautiful clean bathroom, this all takes only a few minutes and I always have a clean bathroom.

The right side of the room is looking towards the ocean. I plan to have a fan in the middle and would like lights on each side of the fan but not down lights. I will explore your suggestions. Thank you
