To object to the mural

I'm all for art but I can see equally eloquent graffiti on pretty much every railway bridge. So it's not for me - and I have to wonder why they think it's appropriate ?

Love it.

Certainly not attractive but it is on their own wall so not much to be done about it. As DaphneBroon says a trellis would hide it ..

what does it say ?

A very large trellis is called for.
Ghastly.

What does it say - I can't figure it out?

I wouldn't object - as hildajenniJ says, each to their own. They'll get bored of it soon enough and have it painted over.

It's still neat and tidy, the lawn is beautifully mown. It isn't what I'd paint on the end of my house, but hey ho, each to his own. I think it's called graffiti art. It may not suit the area though, and if there are complaints, the local council might ask them to paint over it. They could invoke a section 215 notice. See here

It's hideous! What on earth were they thinking?

Oh good grief! Have you spoken to your local councillor or planning officer about it, or even your local paper?
