No, not thought about that actually. I am thinking of curtains/drapes but worried they would mould or look a bit naff from the outside

It makes me cross that people think they have a right to make some quite negative comments on this post. Masmccar76 put these photos on because she thought people would like to see a genuinely lovely transformation of her garden. Instead there have been some downright nasty comments. By all means make comments but keep them constructive. Houzz is all about is sharing ideas, not about being nasty

Put in a few French drains where you dig a ditch and fill it with crushed rock to help the water drain. In low spots put in some drains [http://www.homedepot.com/p/Tuf-Tite-16-in-2-Hole-Drain-Sump-with-Grate-and-Seals-2HDS-4/203463511] with pipe running to the French drain. You might also need to bring in 10 yards of top soil along with some sand to raise your yard a bit as you're probably right at the water table level. We've had to do all this as we live in the Pacific Northwest in a reclaimed marsh [a nice word for a swamp] where we hit the water table if we dig down 3". We had to put down about 10 yards of top soil along with some sand to raise our back yard. We also dug a French drain along the back to connect to the associations drainage pipes through the neighborhood. My husband has put in at least 3 of the drains in strategic locations around the yard to help drain off the excess water. Our yard isn't perfect, but it isn't the swamp it was the first couple of years we were here. We have to apply moss killer every spring or it takes over the yard. My husband also puts down lime to soften the soil, and help the water drain easier. He and a friend rent an aerator every summer and do both our yards to help with the drainage as well.

As you've got the Abbey Road sign, why not make it a music corner? Perhaps a Beatles inspired / Sixties monochrome scheme. You could get a musical notes design printed on an outdoor canvas for the wall, or a sail & hang over to create shade. Perhaps some instrument outlines on the wall. Planting could be black & white with pops of colour. A decorative white chair & outdoor rug would look inviting. Or you could even paint boards b&w stripes like the zebra crossing!
