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.

I think your current room already feels classic - 1960's. I like it! The Hamptons look is heavier in form but lighter in colour and I think a whole wall of white would be too much. Think carefully about what it is you don't like Hamptons is trendy right now - but will you think of it as classic in 5 years. I think the issue is the handles- and that the middle shelves need to be reworked to fit the Tv. Before you spend a lot i would have a go at styling the shelves- Houzz has plenty of images.

The whole place has that 'of a certain period' look , but I suspect it can be done . The 'reverse' side of the bench in pic 1 has to go -- it looks cheap veneer that has overstayed its welcome ! Black or white gloss Formica or similar would lift that . The lino would need be modernised -- maybe tiles , maybe just 50 year newer lino , or wood planks would look mutual and modern , and reference the benchtop too . The wall tiles ditto -- remove and replace . Gloss white or black or charcoal . Or a colourful splashback , either the full width or maybe as a centrepiece 1.5-2 metres long , in a red or green or yellow or similar . Above that paint in ( I shiver as I write this ) grey . Maybe a 'frieze' of contrasting but complementary subway tiles , attached vertically to add some bulk . Ordinarily , I'd suggest cupboards or even shelves or a display cabinet above that , but anything added would look so out of place it would be hard to pull off , unless you matched the timber benchtop , and that would be difficult . And presumably change the cupboard handles -- a trendier stainless or chrome design would tie in with the sink unit .

First - fix the proportions. remove the square hedge and possibly second hedge in front of the window. The fence on the right should be moved back in line with edge of house as it is making things look out of proportion. Colours - You need more contrast - keep the bricks, paint the garage darker, maybe charcoal. The arch - The arch around the entry is a bit off putting - I think it is because it is blocking view of the door. Could it be removed? If not, might first idea is to add some malibu wood paneling near the door or make a little wooden entry deck in the malibu. Second idea is to grow some vines or greenery on it. and remove the three little scrubs. Or instead of vines add two big potted plants on each side of the arch to make it more welcoming. Hope that helps Best of luck
