That would definitely help. Then design a room in the new home with appropriate ratios, but even with, as I discovered, one needs a minimum of two subs to combat the inevitable room modes. Design for front-center and rear-center placements. Or go all out with four in the corners.
Yep, and availability of materials and staff. A home 1/4 mile from me has been under construction for >14 months, and it looks like move-in won't happen for another couple of months.
So if you spot an existing home for sale with close to what you want, it might make sense to evaluate, as the stress and aggravation of building, along with the time, are a cost as well. I know, my build took 14 months, and cost 70% more than budget (some of that self-inflicted).
