That is a cross between a shed and a cabin... We are going to buy(we think) a 16' wide x20' long x17' high gambrel style barn/shed thingy.... We saw one while on our 'mini-vacation' in NC and it comes out to be about 700 square feet.It costs around $8600 built on your land.It has no insulation but we thought we could do that ourselves and then panel the interior walls and lay some flooring as well as put in cabinets and a bathroom. We drew up a plan and we could have a bathroom in one corner under the stairs and a kitchen running along one wall. The main double doors we would not really be used(put a sofa in front) but we would still have them as it will make it easier to bring furnishings and cabinets,etc in while constructing the inside. The side door would be at the foot of the stairs so it would take up less floorspace. The entire upstairs would be bedroom. We are going to find out IF we can have the septic installed for the main house and tie the 'Shabin' into that as well as run power to the site.Power is at the property line but not sure if the Power Co. will run it to the site with no home present. Water will be hauled I guess at this point or possibly a well drilled although that is MORE money. So we are hoping the 'Shabin' with power,septic and plumbing will come in under $15,000.... And it will enable us to have a place to stay that is permanent and can later be used for a guesthouse. Anything we missed???
