How close to the house can I plant G. mannicata? I know it's very thirsty

You'd probably need to worry about shade, too! Ours has its feet in water,
admittedly, but it grows to 9 or 10 feet tall each year, with at least that
spread! I don't know about the root system and subsidence, sorry.

As they need their feet in water - or at least very damp - wouldn't it
get a bit thirsty? Unless you had a bog next to the house in which
case you'd probably get rising damp.

You could try planting it in a large buried container I suppose;
that's what's going to happen to mine when I plant it out. It's
overwintering in a pot in the cold spare room ATM.
