An interesting twist on a typical dog house, you can build this outside structure either as a simple house with platform or go all out and add an upper sun deck with stairs. The dog house itself is a hybrid between building a simple box and proper frame building construction.
For Optional Stairs, Top Deck and Railings:
Frame out the base. Cut (3) 2x4 PT studs 5’ long, and (2) 2x4’s PT studs 4’ long. Frame a box with 1 board as a center support and you will have a 48” wide by 63” long base to attach the floor boards on top. Use 3” hot dipped galvanized nails here.
Attach the platform floor. Cut (11) 1x6 PT boards 48” long. Nail in the 2 end floor boards first, then evenly space the rest of the floor boards about ¼” apart. Use 3” galvanized nails here as well.
Frame out the house side walls. Since this house needs no rafters, we will pitch the side wall top plates to match the roof pitch. We can do this by cutting the wall studs at an angle. Cut (4) 2x3 pieces each 39” long for the top and bottom plates. Then set your miter saw to 18.5 degrees. Measure out and mark a 2x3 stud at 2’. Cut this stud so that the 18.5° extends rather than reduces the length of the stud. Repeat this twice so you have 3 left side angled wall studs. For the 3 right side studs, repeat as above but mark the initial length at 3’. Assemble the walls with 3” nails through the top and bottom plates. The third wall stud should be centered.
Set the left side wall frame on the platform along the left rear edge and nail it in through the base plate with 3” nails. Cut one 2x3 piece 31” long and set it along the back platform edge. This represents the rear wall length. Set the right wall against this board and measure the front edge so it also sits 31” in from the left wall. Nail this right wall on to the platform using 3” nails.
Frame out the front and back walls. Cut (2) 2x3 pieces 8 ½” long to serve as the front bottom plates on either side of the door, which is a 14” wide opening. Rather than measure the studs and top plates, mark the lengths and angles by holding a roughly 33” top plate in place between the side walls and setting the studs in place one at a time. You will need studs at each end, one in the back wall centered, and 2 framing the doorway in the front for a total of 7. Assemble the wall frames and nail them both to the platform as well as the side wall studs using 3” galvanized nails.
Cut the siding into (3) pieces 41” square and one at 41x29”. Set the front piece in place and mark the outside edges. Also mark the doorway cutout against the studs. You can make the height any dimension you want, but follow the roofline angle for your cutout. Nail the siding in with 2” galvanized nails and repeat with the other 3 walls. As an option, you can cut leftover siding into corner strip accents as shown in the picture above.
Cut 1x6 PT boards to create a 2” overhang roof edge on all sides and nail these boards to the top plates. Cut the plywood into a 4’ square and set it on top of the roof edging. Scribe the actual size and cut the lines to fit. Nail the plywood roof in with 2” galvanized nails.
Set, mark and cut drip edge to length and nail into place along the roof perimeter, starting at the left wall and working your way up. Install the shingles, using a starter strip along the left wall edge. Use the utility knife to trim the shingles to fit. Always work up from the lowest roof edge.
Optional Rooftop Deck and Ladder:
Step 8: To make the perimeter upper deck frame, cut 2x2s to match the outside edges of the roof and assemble the frame with 3” deck screws. Cut (2) 16” 2x2 deck support pieces. Set the frame on the roof, bring the low end up to level and use a piece of scrap wood to prop it in place. Set and mark the final height of the supports as they sit vertically on the roof extending up to the inside corner of the frame. Cut and screw these supports into the frame. You can now screw the supports in to the roof on the low side, and the frame directly onto the roof on the high side. Remove the scrap piece.
Step 9: Cut (10) 1x4 boards to length front to back, space them evenly and screw them onto the deck perimeter frame. Cut (22) 9” 2x2 baluster pieces for the railing. Screw in 5 on each of the front, back and left sides evenly spaced on the outside of the decking. We will use the rest of them later.
Step 10: Using 2x2s, make a box 12”x18” to serve as the stair landing. Attach this with screws to the right rear side of the platform. Use a roughly 3’ piece of 2x4 leftover from the platform to construct a prop column running vertically from the right rear platform corner up to the landing. Cut (5) 1x4s 12” long to finish the deck. Now you can attach the remaining balusters and cut 2x2 railings to fit the entire perimeter.
Step 11: The ladder is built from 1x6s. Cut one end of a 1x8 at a 45° angle. Set it on the platform edge near the front and scribe the corresponding length that reaches the landing. It should be around 5’ with the scribe at 45°. Now make a duplicate so you have 2 identical stair stringers. Each stair tread is 9” wide, and set at a 45° angle so they become level when the ladder is installed. We used 6 treads, but for smaller dogs you may want to make more. In any case, attach 1 tread at the very top and bottom, and space the rest evenly up the ladder. Set it in place and screw it into both the landing and the platform.
Now that construction is done, you may paint, stain and/or decorate your pet’s new home any way you desire. Let your imagination go wild. “Ruff” can’t wait for his new porch umbrella! I think that a bigger doggie bed is in the cards as well.
