Before the invention of inside toilets, outhouses were used. At first, these wooden outside privies were thrown up without much thought of design or appeal. After all, the whole purpose of an outhouse was to be able to sit down in relative comfort on a bench with a hole cut into it instead of standing or squatting in the woods somewhere. Now that your basic needs are covered indoors, an outhouse can be a creative and functional outlet for your design skills.
Measure how big you want your outhouse with the tape. Use the pencil to mark where you need to cut the plywood, tin and boards to size.
Plug the skill saw in and cut the boards, plywood and tin according to the measurements. Set them aside.
Build your frame over the hole for your outhouse using the two-by-fours. Build the bench, making sure that you cut out a hole to sit on and then connect the plastic toilet seat.
Nail the rest of the boards and plywood to the sides and back to the frame, leaving a piece of plywood for the roof. Cut out a door from a sheet of the plywood and hang the door using the hinges.
Nail the last piece of plywood to the top of the frame for the roof and then finish by nailing the piece of tin you cut earlier on top of the roof.
