Depends on your layout,
I have 50 acres I camped at,
Camped down wind and far away from a bedding area,
I now have a house on part of it which I rent out,
Am currently thinking of building a rustic camp on 8 acres toward back end,
it is very close to a bedding area , so still thinking about it, but my land borders thousands of acres of state land that I can hunt if I push deer there.
Keep it simple, and should have minimal impact.
Since your only 40 minutes can probably do without a roaring fire for cooking, maybe think of a camp stove for simple cooking/coffee or electric heater for heat.
