What a beautiful space. Love it! It is difficult to tell by the picture, how much space you have between the edge of the pool and the wall. But here are a few ideas for your consideration. Thank you!

add a planter against the wall

maybe add a narrow bench against the wall with pillows. You could create a small table on each end of the bench to set drinks & candles on table for evenings. As well as a fire feature

corner bench where you could possibly put your feet in the pool while sitting. Add fire feature on each side of the bench for evening. Do you have space to add plants on top of the wall as in this design.

Add some metal décor on the wall. Using décor with words is also a nice design element

Tile the wall. If you like more modern, tile can be added in a stacked pattern instead brick.

You could add some wood on front of the wall to break it up. Put wood in strategic places as to not cover up the wall entirely.

Perhaps some laser metal art with solar up lights or down lights would look great and some potted plants

Really nice space. Be careful about cluttering it up too much.

Barbara's link didn't work for me. Liking the idea of facing the wall to change the starkness of the all white: perhaps a combination of stone and wood, leaving some large what spaces of the original wall showing for hanging art -- pressed metal would work well.

That is beautiful! Please find a great local designer to work with because they're not making more of those gorgeous mcm backyards.

IMO what you have is perfect simplicity is IMO the real watch word for thse homes.Maybe a bit of clor added for some of the loungers is all I would do with a few mor planters.

Acme House Rentals

One more try. If it doesn't work, just google Acme home rentals.

To me the all white and concrete yard is a bit too austere. It seems more minimalist than MCM.

I'd like a custom made iron piece for the back wall as show in one of the images above.

A potted tree in the corner would be nice too.

Are you in Florida?

Yes we’re in Sarasota but only part of the year so we hesitate investing in large potted plants that would require regular attention.
