Aha, Small. Have you added the garage and room above to the house, or are they just hidden by the camera angle in the first photo (and who is that on the lawn by the way? Even with Massive's megazoom function I can't tell whether it's you)? Anyway, it's a lovely house and the front garden is much improved by the addition of the front path. I think as you've already got ivy, something with flowers would be nice so, as it's quite a trad house, how about one of the roses? Because roses don't cling, you'd have to put up some sort of framework for it to be tied to, but that might be preferable to having to prise hydrangea or ivy aerial roots off the windows.
I've been on Twitter for a long time but (with very few exceptions) I use it only to follow people and organisations I'm connected to professionally. The whole Kevin and Perry Twitter Lucas thing put me off using it for, ahem, role-playing games.
