Yes you would......Mine is 7400sq ft main house with an attached 1800sq ft 6 car garage. 1250sf guest house that my Mom lives in and a 3000sq ft Shop......
3 seperate structures.
I use every bit of it!
I've lived in a 2 bdr cabin in big bear, the whole family.
I spent 10 yrs of my childhood in a 2400sqft house, it was plenty big for 4 people and it had a 1200sqft guest house out back, black smith shop,pool yadda yadda...and before that we lived in apt's and rentals, I don't see myself needing even that much house.
I have a spare room for my 'in house hiding' or dads spot and I have my lil cave attached to my car port.
You must have a fun time keeping up with the house/s and other buildings when it comes time to clean.
I would love a 3000sqft shop...TO WORK OUT OF...lol
I live in the same size house your mom does, I could maybe see utilizing another 500sqft but after that...i have nothing I would do with the rooms...unless I had a bunch of people come stay with me.
once you get over 6000sqft it becomes a mansion.
the one thing I would like in the future is a lot of land around my house to keep some distance between I & the neighbors.
I require less materialism in my life than some.
I guess I grew up different than you guys, thats diversity for you.
