Thanks, Ian. We have an east-facing wall, and a south one, though that one doesn't get the sun first thing, nor after midday. We'll try the south one and see how we get on, I think ... Simon's all enthused now too, and might make a second house. If he does, we'll try that east wall, which gets the very early sun and is slightly more sheltered.

interested to see your photos, if you can do them, Marek.
