Our place has evolved over time, with increasing utility. Each major step in improvements has opened up broader use. I’ll outline them to show at least one set of steps.
The house is old - 1799 - but was never modernized and utilities never brought it. In 1985 it was essentially the same as it was in 1799. With no running water and no flush toilet, use was limited to a few days before you really wanted a shower badly, and only hardy guests would go.
In ‘85 we put in a gravity feed dug well and a septic system, plus a propane water heater. Then a regular bathroom. New also wired the house because we had all the walls open to insulate, but all you would do was plug it into a portable generator. This transformed the place completely, and made it accommodating for anyone, and you could stay as long as you wanted. Heat was via a wood stove only, and the road was not plowed. We designed the plumbing carefully so you just needed to open a couple of valves and everything drained so it wouldn’t freeze.
In 2000 we took another big step and installed central heat via propane, and put in a small solar+battery system to run the furnace circulator and to have lights. Refrigeration was all propane. We also hired a neighbor to keep the road plowed. With this, the place was usable year round, and you could just roll in at any time because we kept the heat at 55 when not there. We also added a full laundry, making it a fully functional house.
Since then we have made further improvements and expanded to include a full shop. One big step was a major fix up on the road, filling soft spots with rip rap and then covering the whole road in hardpack. Prior to this, the place was inaccessible during mud season.
Now we live there full time. It’s still off grid, but we barely think about power.
Somewhere in this spectrum I’m sure you will find what fits your needs and goals.
