We do not have land yet. We expect to be able to buy in the spring. That is one reason I am trying to figure things out now -- so we can look for the right features to fit what we want to do. There is a 5 acre lot currently available that I like, but it might not still be available in 6 months, so I am not counting on it.
Our 6 kids range in age from 2 to 17. The oldest is planning on moving out on her own next summer, so that will leave the next oldest at 14. I would like (for family harmony's sake) to give each child their own (tiny) room. It would be excellent to double them up, but I think they would kill each other. I like open concept design for the common rooms. My ideal layout includes greenhouses comprising the south wall of the house and a root cellar. The house we currently live in (my mother's) is about 2000 sq. ft. and this seems just the right size. We moved up from 1000 sq. ft. which was definitely too small for 8 people. The kids are in three singles and a double room (that we carved out from the enormous living room by using bookshelves as walls), and the toddler is in our room.
We do plan on practicing permaculture. We want to supply as much as of our own food as possible, with chickens, a few cattle for milk and meat, rabbits, and a garden. We have a dog and plan to get a cat. We've been told we should get a llama. Sheep are not really on my radar. I want a field with lots of wildflowers, and forest from which we can harvest deadwood for a woodstove for heat and cooking. Windpower is a very viable option (our town has a commercial wind farm). We want to live as an integral part of the land. I spent 6 years of my childhood with neither electricity nor running water. I look back fondly on those years.
Skill sets: When I was 8 I watched my parents build a small house (I even helped hold nails and such) that we lived in for 3 years. I am quite handy - I have built some few pieces of furniture for us (a roll-out pantry, a dining table, a tall chair for the younger kids, etc.). I am a seamstress by training and have pretty good 3D spatial skills. My husband has helped his father with light maintenance on his rental properties and reshingling roofs. He is comfortable working with 110 electricity as long as he doesn't have to mess with the box. We replaced almost the entire indoor sewer lines in my mother's house last summer. He ran ethernet cable through the house, too.
My husband works full time right now, and I just left my part-time job to take care of our toddler during the day. I am quite happy to put in hours of labor. My oldest said she is willing to help out with manual labor, too, if necessary, even after she moves out.
