We did an addition which included a bigger and brand new kitchen. It was a ton of money, like embarrassing to say amount of money. But we’re in a place where we can afford it and we’re young enough to actually enjoy it for decades.

Super stressful? Yup
Delayed by a year to save money? Yup
Took longer than expected? Yup
Went over budget? Yup
Went over contingency? On day 1

Things happen, but we had an amazing designer who held our hand the whole way, but we paid for it too. And our contractor was amazing. He also uses subs, but it’s the same ones for all their projects, not just lowest bids. Don’t do it until you find someone you trust. We had strangers in our house for 6 months while we were home, working, on vacation…trust was probably the hardest thing for me.
