This sturdy dog house will keep your best friend warm and dry, and you'll have fun making it. This design features a removable roof for easier cleaning, and the floor is raised off the ground to keep loyal companions protected from rainy weather.
This plan will accommodate dogs up to 60 pounds, but it can easily be modified to fit a dog of any size.
Rip and cross-cut the sides (B), bottom (C), long roof (D) and short roof (E) from exterior plywood to the dimensions on the cut list. Unless you are working with a large support for your table saw, you should make your first cuts from a full sheet of plywood with a circular saw and straightedge as a guide. You can then trim or cut smaller sheets to size on your table saw.
To make the front and back pieces (A), start by cutting two squares measuring 36" from your plywood. Clamp them together keeping all edges flush and lay out the roof angle cuts according to the measurements on the illustration detail. Using a straightedge as a guide, make the angled cuts with your circular saw.
Attach the sides (B) to the back (A) by drilling countersunk holes through the face of the back piece and into the edge of the side pieces. Attach with glue and 2" deck screws.
Lay out the door opening on the front piece (A) according to the measurements on the illustration detail. Drill a ¼" pilot hole inside your opening’s marks to insert your jig saw blade and cut out the opening.
Place two scrap 2 x 4 pieces on edge inside the side/back assembly and place the bottom piece (C) on top of them. Drill countersunk pilot holes through the sides and back and into the edge of the bottom piece all the way around, spacing your holes about 6" apart. Remove the bottom piece, apply glue to the three edges with pilot holes, place it back inside the assembly and attach with 2" deck screws.
Put the front piece (A) in place and drill countersunk pilot holes through the face and into the edge of the sides and bottom piece. Remove front, apply glue to those edges and attach the front with 2" deck screws.
Make the roof by drilling through the face of the longer piece and into the edge of the shorter piece along the 48" long edge. Apply glue to the edge of the shorter piece and attach with 2" deck screws. This step is easiest to do with the roof panels standing up on their shorter edge (front or back as opposed to top or bottom) on the floor.
Rip your 1 x 4 lumber in half, resulting in two pieces of lumber about 1 5/8" wide, then cut all corner trim pieces (F) to 17" long. Attach them flush with the bottom of the dog house and overlapping the joints as shown in the illustration. Attach with glue and brads or finish nails and hammer.
To assure a tight fit for the roof trim, start by cutting a 45° angle on one end of a rake (G), hold it in place under the roof edge and mark the other end at the bottom edge of the roof. Cut a parallel 45° at that mark and then attach with glue and brads. Repeat this step for the other three roof rake pieces (G). Once they are attached with brads, go back and drill countersunk pilot holes through the roof top into the rakes at 6" intervals, then attach with 2" deck screws.
For the fascia (H), measure between the rakes or hold a piece of trim and mark it and cut it to length. Then rip a 45° bevel along one edge to match the bottom edge of the roof. Attach with glue and brads, then countersunk screws as with the rakes.
Apply roofing felt on top of the roof, roll it out and let it overhang, then trim it flush with a utility knife after attaching to the roof with staples. To make a starter strip for your shingles, score a line on the back of a shingle along the top edge of the cellophane/adhesive strip. Bend at the line and break the shingle apart. Place it on the roof face up with the adhesive along the bottom edge, keeping the shingle edges flush or overhanging the roof edge just a bit. Attach with roofing nails (3 along the top of the starter strip). Continue along the entire bottom edge of both sides.
Apply shingles as you would a regular roof, starting from the bottom, overlapping each course and staggering the shingle slots/seams.
Finish the peak by applying ridge caps. Cut a shingle in thirds, and then cut back the top half at a slight angle so it will be hidden by the next layer of shingles applied on top of it. Apply them by bending the shingle over the peak and attaching with nails just above the adhesive strip, about 2" in from the angled edge. On the last ridge cap, nail through the face of the shingle and apply a thick bead of silicone sealant over the nail head.
Fill all countersunk screw holes with wood putty, make sure all nail heads are set and sand everything smooth. Apply exterior paint and/or finish according to manufacturer recommendations.
