Yes. Or no.

You've given us nothing to base a choice on.

We ned a lot more info and pictures . Is this a new build, or are you thinking of adding a 2nd storey. A home is what you need for your family not what every other tom, dick and harry needed for theirs. If you want to know if it will affect resale talk to a realtor in your area.

You want to pay to build an entire new house, on top of your existing house. And move out for a year while that happens. Plus the inevitable damage to the existing original house.

what live_wire_oak said. better to find a house that's already two stories than to pay just as much to have a house that's too expensive for its neighborhood, if you can even survive the project.

Thank y’all so much for your feedback. I didn’t realize it would cost that much nor take that long to build.
