DIY Low-Roof Shelter

Draw a design that fits with the landscape, selecting a roof shape you can assemble at ground level or reach from scaffolding. Design the framework to hold the weight of at least two people on the roof, so shingles or metal roofing can be applied without the structure collapsing. Research information regarding rafter span, meaning the distance of roofing boards without support under them, to figure out measurements needed for a strong framework.

Build a concrete slab foundation for the house framework to rest on. Rent a trencher to excavate the foundation. Roll out metal gridwork to support the concrete pour to form a slab that is at least 6 inches thick. Plan and install plumbing drains appropriately before the floor is poured.

Lay one row of concrete blocks around the perimeter, installed with mortar, so framework can rest on blocks versus directly on the slab.

Cut 2-by-8-inch boards to assemble the wall framing. Build the wall sections on the slab with all component parts laying flat on the ground. Ask friends to help lift the walls into place for assembly. Install 8-inch wide framing boards, instead of smaller boards, especially if the area has strong winds or storms. Make the walls of 2-by-8-inch boards to allow deeper insulation as well.

Cut framework with a circular saw, making sections for the bottom plate of walls first. Install studs on 16-inch centers, capped by a top plate for each wall section. Nail 10d nails directly into the studs from the top plate and bottom plate instead of toenailing them in at an angle.

Construct framework for doors and windows in wall sections that require these openings. Cut the opening for a window, for example, by cutting cripple studs (short studs) to fit over and under the window framework. Install a king stud on each side of the window with a trimmer stud fitted next to the king stud. Add extra support around windows by cutting sturdier framing boards, especially if heavy windows will be used.

Secure the wall sections together in a rectangular, square or octagonal house shape, depending on your design. Complete roofing framework by installing ceiling joists to fit the top plate at the correct angle. Cut roofing rafters with a miterbox saw or reciprocating saw after marking the correct angles for cuts.

Drill pilot holes to bolt the roof to wall framing, if you plan to move the shelter at some point. Connect various sections of the roof with bolts, so that taking the roof apart in various sections works more easily.

Cover the house exterior with faux wood siding, and add asphalt shingles over tar paper underlayment. Add windows and doors, along with sections of appropriate exterior trim around windows and doors.

Finish up the interior last. Run wiring for electrical needs and any plumbing pipes or drains needed while walls are open. Install fiberglass roll insulation between studs. Secure basic beadboard paneling over interior walls with screws. Drill pilot holes for the screws, so the beadboard can be removed if the house is ever relocated.
