I'm going to share something quite personal and very pessimistic. Please know that I'm coming from a place of sincerity and caution. I'll try to be as careful of my phrasing as possible.

I'm always slightly uneasy when people build houses based on a plan to have a couple of kids in future. I'm only 36, but since we were in our twenties slightly more than 50% of the couples we know have had trouble conceiving or were completely unable to. That includes couples in their twenties and thirties. And that's only counting the couples who were open about wanting to start a family and being unable to. It does not include already established families with kids or people without kids who didn't share their reproductive history with me. Just because you plan kids doesn't mean you will have them or that they will necessarily come right when you plan to have them. People do sometimes have to try for decades and that experience is getting more and more common.

This house has four bedrooms. That's very generous for a family of four; it's enormous for a family of two. So my advice would be to find a modestly sized house that would be sufficient for two or three, in a good neighbourhood, and when the time comes to upgrade for your growing family do that then. Since this is a bit too much house for two, and there are awkwardnesses with the layout that will become problematic if and when you have a couple of teenagers, I think you could be better off just meeting your needs now and for a few years in future.

Again this is a pretty personal thought process and others might take a completely different position. This is just mine. And obviously I hope for the *best* for your family, whatever that looks like :)
