There are tons of papers available that would go with your midcentury home. Many people tire of a paper quicker than they are ready to redecorate and they can also look dated in a couple of years. Metallic papers were big im midcentury...perhaps a metallic silver paper? Are you also considering paint? You can get it in so many textures and a blue wall to match the blue in your loveseat would be lovely with some midcentury art and sculpture, or photographs on it. A mirrored wall with or without art or sculpture would also work with midcentury. These treatments are easier to adapt should you wish to change the look slightly from time to time. I would suggest replacing your stairrail with chrome or acrylic if that is in the budget...see how well the loveseat frame looks with the fabric? I hope you will post the "after" photos for us to see. Above all, enjoy the process!

Thank you for your help, I had never questioned my taste until a recent visitor commented on my lack of color! I like the look of the mongolian lambs wool cushions-have not seen here in New Zealand, I will have to search. Thanks for the reminder about mirror, it mostly does reflect the dresser but yes the doors are focal too, I hadn't noticed. I used to have more height on the living area coffee table but when I removed the Television and hung the vintage ceiling tiles (photo attached) on the wall the height interrupted them from another angle (not photographed). Our house is located semi rural with bush and water views, with this being quite focal in the lounge (with the wall paper) which is why I have not hung art. With this (as photographed below) would you still hang something? Really appreciate you all taking the time to answer. Thanks.

congrats! first, sand prime and paint out those cabinets....i'd go with a grayish shade of white or pale gray that will work with the flooring. i'd also carefuly chip off the yellow tiles. since on a budget, consider applying some beadboard as your backsplash, painted in a glossy, oil based or marine paint in a crisp white to keep it scrubbable, then, dress up the edges with some small mouldings, painted in the same white paint. this is going to be SO MUCH less costly than tile! and it will look great with the butcher block countertop. you can probably refresh the butcher block with a light sand and oiling. you could even get an additional piece of butcher block (ikea) and create a step-up 'bar' for some stools on the peninsula for some casual seating. then get a pair of pendant lights to hang from the pot lights above (they make lights that insert directly into the pot light...no hardwire necessary).

Do you want this to be a big reno? meaning, will you replace things totally or do you want to work with what you have mostly? will you add a toilet to the bathroom? if you replace the vanity, you can put in a larger one curving around the corner with a medicine cabinet above. If you replace the shower with one flat on the ground, you can also put in clear doors for bigger visual space. how about re-painting as well
