I agree with this. Spend a couple bucks to get quotes from engineers and contractors. The “worth it” part will be answered by their quotes, which you set along side comps for houses that are similar to yours with the added space, and what that space allows you to do that you couldn’t do otherwise.
10 years ago it was DeWalt, now it’s Milwaukee. Was excited to see them come out with a battery powered lawn mower, until I realized it costs over $1k!
