This is what I would ask myself…
Have I taken the stormy weather into account? sheltered spot out of the wind. Stable trees. No flooding risk or soggy ground.
Is there a view so that each cabin remains private but also gets a good view from inside as well as from a deck.
Is there room to park a vehicle very close by without it being in the eyeline of other cabins.
Does the site get plenty of light/sun. Could I position each cabin to maximise light, yet maintain privacy.
Can I afford en suite facilities, cooking facilities, log burners inside as well as fire pits and hot tubs outside. Am I prepared to empty, clean and refill hot tubs after each couple.
Have I spent a summer there, in the evenings, to measure the extent of Mosquito problems.
Is there a local attraction eg farm for milk and eggs, waterfall, bird hide, pretty picnic spot, lake, castle, hill top, village, in walking distance.
Is it a Dark Sky area with no light pollution. And no sound pollution.
Shepherds huts work well in Wales for weekend couples most of the year round providing they are beautifully equipped, with a log burner, free logs, a view and a private hot tub.
