At least you can move it with a car jack! If I built it, you'd need a bobcat! I always over engineer things like this. I build for hurricanes in earthquake land. As far as the 3 men and one girl, this girl can move it, but I'm smart enough to ask the men to do it for me

I used to move stuff myself, now I just ask for help and things miraculously get moved

Let me know how you feel about the bungalow. I checked out your parlor, if that bungalow is anywhere near as sturdy, it's a great deal! I'm really hoping to not have to build it. We have a giant Cooper's hawk that lives next door. I think I'd need 2 or 3 rolls of hardware cloth to fend off that beast. It dive bombed my husband and I last week!! We had the chicks out in the front lawn and this huge hawk swooped down over us and landed on our rain gutter with a huge clatter. It was crazy! We are both well over 6' and this hawk did not care. He saw chicken dinner. He did not get one, but it inspired me to make a predator proof coop a priority.
Let us know the bungalow works out.
Oh and don't feel badly about the old house needing work- we have a 1927 Spanish. One of our bathrooms doesn't even have a sink. It stopped working and we just ignore it! We'll get around to it some day. Old houses rule, even if they go on strike sometimes.
