0.25 acre house plot
0.75 acre garden (bio-intensive carbon farming, cost = 1k)
0.5 acre chicken plot (possible grain-fed sheep too, cost = 1k)
0.5 acre fish pond (could be 1 big pond or a series of smaller pond for $3k)
1 acre orchard (180 trees at 15ft centers at $30/tree for $5,400)
(Sub-total = $25.4k)

Septic = $2k
Well = $4k
Electric = $3k for 10kw propane generator
Propane = $1k for 1000gal tank
(subtotal = $10k)

ERV = $1k
A/C = $3k
Radiant Heating = $3k
Tankless Water Heater = $1k
Plumbing = $1k
Electrical = $4k
Laundry/Mech Room = $3k
Bathroom = $3k
Kitchen = $5k
(subtotal = $24k)

House Shell = $40k

Optional
Solar Electric = $27k for solar (10kw panel, 11kw inverter, 20kwh battery)
Silvo-Pasture = $30k for 6acres

At the lowest point in the system put a weep/leak hole in the pipe. Just big enough so that their is no standing water in the system after say 3hrs.

Maybe a diy value that closes when there is a positive pressure coming from the washing machine but then opens after that pressure goes away.

Balecob doesn't have to be square

Don't let labels get in the way too much, you are going to need wood-framing (Roof, door and window jam, maybe floor/internal walls/etc). You might go with a cement/metal/stone/earthbag stem wall. Don't be too afraid to mix and match, because in reality you will have to.  

I would like to introduce you to balecob. Some say it is the best of all worlds.

I would say 2.5acres or 1 hectare is the perfect/max size. Over 2.5acres and you would need machines/help to manage it.
On the lower end (after years of building max fertility, perfect species/cultivar selection, perfect watering, in a zone 10), maybe quarter acre per person.  

This might be your best year. Getting them to ripen on the vine has been a no go for me.

To me instantaneous renewable energy could be:
1) firewood/bio-diesel to heat or run a mechanical engine.
2) hydro to power a mechanical mill or a hydro-electric turbine to make electricity, a mechanical mill can also operate a heat pump directly to make heat too
3) wind to power a windmill (mechanical or mechanical-electrical, etc)
4) solar (Thermal and electrical)

To me stored (renewable) energy could be:
1) firewood/bio-diesel that has stored/converted solar energy to chemical energy
2) pumped-hydro that is converted electrical to potential energy at a higher elevation in a dam.
3) pumped/compressed air
4) chemical battery that has stored electrical energy as chemical battery
5) stored hot thermal energy as in molten salt
6) stored cold thermal energy

I have a possible solution, Radiant heating, 1000ft+ flexible pipes filled with warm water in between the basement ceiling 'beams'. It will lower the humidity levels of the basement. And provide a much better heating system for the 1st floor. You can insulate the walls of the basement with rigid insulation (think foam plywood).

Assuming that your 8,000sqft plot of land is 80ft by 100ft. If you plant trees every 10ft you can fit 36 trees. Thats quite alot.

I would start off with
1) vines: grapes(Mascadine, European/reg, concord/northern), kiwi (artic, fuzzy/regular, hardy), akebia, shizandra and maypop/passion fruit.
2) berries: blackberry, raspberry, currant, gooseberry, jostaberry, blueberry, aronia, honeyberry, goumi, seaberry
3) pawpaw, quince, asian persimmon, asian pear, jujube, figs, dwarf mulberry, pomegranate, medlar, shipova pear
4) bush cherry, sand cherry, beach plum, apricots, plums
5) the last thing I would plant is regular apples/pear, peaches/popular cultivars of stone fruits they require too high-maintenance. Unless I was planting from seedling and let 80% die/cull and only keep the best 20%.

They are nuts. You can make oil from it (coconut oil/palm oil/etc). You can also get nut flour/meal too. And for a few some kind of date like fruit. You can also tap the tree to get sap to make syrup/sugar/wine/vinegar/kefir/etc
