Thanks for writing. Without being able to see your yard in person I can't give you any specific planting ideas, but in general, I've seen ornamental grasses used to great effect to hide gas meters and other utilities. They're beautiful during the winter and can easily be pushed aside so they don't prevent utility workers from accessing the meters.
As far as planting ideas, if our garden plans don't work as a whole, don't be afraid to customize them by ignoring sections of them. For example, if there's a plan you like but it's too big, feel free to simply ignore part of it so that it does fit. Or, you can also link together different plans by planting them against one another so they feel like they're a part of the same bed.
Have you seen our collection of small garden plans? Maybe there's something there?
