Business at the front, party at the back.
I have looked it over a few times and am still confused about everything stuffed in the back garden - an extension for tiny pottery houses, a converted bathyscaphe, a fountain that looks like it came from a funfair and a tree house. All that before you get to the loft conversion that has the feel of a small caravan (we used to go on holiday in a Sprite). 🤷♂️
Looks like the estate agent wasn’t brave enough to create a floorplan
Or it’s impossible to map without resorting to the kind of non-Euclidean geometry that would open doorways to entities that cannot be named.
