Sorry about the broad question. We are contracting in out, and we are in the design process right now.
I guess I was just looking for very general tips based on others' experiences. As an example, people we know who have had a home built seem to all have little things they love, hate or would do differently about their homes, such as build a bigger laundry room or have a bathroom near an entryway so kids and guests do not have to walk through the entire house to access it.
I thought the HN community may have some interesting insights.
It is hard to give any meaningful comment without more information.
Are you actually intending to build the house yourself, or are you contracting it out?
Is the design set?
