Wallpaper is personal -- it should suit your favorite colours , your house style , your furniture colour , whether you want older scrolls or modern stripes or metallics , etc .

Some other options though would be to just paint one or two as feature walls , add some art , add bookcases ( my preference is full stained timber rather than cheap laminates from the chain stores , but budgets come into play too ) , etc .

You have a couple of plants -- even a larger one in a large glazed pot adds nature , adds interest , adds life , and covers some sins -- as does paint , wallpaper , art , and furniture . Hell , do a mix of all of them , and really lift your place !

Thanks. Yes, mixture sounds good.

As Pottsy has said, wallpaper is a personal choice of design. How brave are you?. The wall opposite kitchen bench could be wallpapered, then just a large artwork in the living area. Or large artwork between the two doors opposite the kitchen bench. There is a good range of removable wallpaper if you do get tired of the chosen design. Not as difficult to remove as glued wallpaper.

Or wrap an “easy to the eye” wallpaper around your kitchen and living wall.

It looks like you have white walls , grey benchtop and light blue lounge suite .

I just googled blue wallpaper , and theres obviously 1000's of designs , but as dreamer said , depending on your taste and braveness , heres one I like --

It is actually printed like that , it is called 3D effect , but it is simply a 2 dimensional trick of the eyes ! Some people would get sick of something like that , but I like quirky effects , and obviously tire of whites and greys in a matter of minutes -- I love things like this !

I'm probably not brave enough for going really bold, but yes do need to add some interest to all the grey and white.

Heres an example of a print available online for under $100 ( with the hidden frame ) , in the blue tone with just enough gold to add interest .

Adds a bit of interest to a pretty 'meh' sort of wall

thanks, thats nice

It’s very hard to get a wallpaper that’s right for you and the room, as suggested it’s a very personal thing to find something that you love and make work, definitely try removable wallpaper, I think large artwork will give a fabulous look, or even a table between the doors that you can add styling pieces, artwork leaning or hang at eye height, adding a rug under sofas and a few more cushions will really bring your room to life.

Or something as simple as a shelf or unit that you can add your own personal style.. could look great.

Thanks, I hadn't thought of putting a narrow table between the doors.
