Large homes aren't actually comfortable to live in.
You need to clean all the floor area of the whole house -- daily, and that's the start. Imagine if the home you live in is like a castle. How long might it take to clean it all? and repeating it daily? Otherwise your dream castle will look like a doomed castle within a month, with all the dust covering everything.
Hiring helping hand is expensive.
Living in a small house with a large exterior open area is a better choice.
