I used a cabin kit as a Bed and Breakfast hideaway on my property. It cost 15k to buy and 20k to build and looks excellent. I was able to get approval from the building authority, and I built it myself in a couple of weeks.
I started a great marketing campaign centered on 'Rustic Cabin' themes and added value with bird watching hides, a flying fox, bicycles, and outdoor fireplace. Now I'm thinking of building another business from the cabin, got any ideas?
