Wicker you're right , it's hard to find the space for the tree, When I look at houses on Rightmove , one of the things that draws me to a house is space in the hallway for a massive tree.
I'm planning on buying a Balsam Hill this year ( we bought a real tree last year and though it was gorgeous , there are downsides)

In winter I need to find space for our guinea-pigs (they have the boxroom, I move everything out) and The Tree
