STEP 1: Base Support

Place the three PT-1 pressure-treated beams on a level surface, following the layout and dimensions shown in the plans. Ensure they are properly aligned and supported.

STEP 2: Floor Framing

Assemble the floor frame using the JF-1, JF-2, BK-1, and BK-2 members. Secure all components according to the layout shown in the plans.

STEP 3: Floor & Bottom Plates

Install the floor panel and secure the BP-1, BP-2, BP-3, and BP-4 bottom plate components according to the plan layout.

STEP 4: Wall Framing

Assemble and install the wall framing using the ST-1, TP-1, TP-2, and BR-1 components, following the layout and dimensions shown in the plans.

STEP 5 — Install Interior Panels

Install the interior plywood panels over the framed walls, securing them to the wall studs. Ensure the panels are properly aligned and fit tightly around corners and openings.

STEP 6 – Roof Framing

Install the roof rafters and supporting framing members, ensuring they are properly aligned and securely fastened to create a solid structure for the roof panels.

STEP 7 – Exterior Wall Panels

Install the exterior wall panels over the completed framing, keeping the sheets properly aligned and securely fastened. If desired, add insulation between the wall studs before installing the exterior panels to improve thermal comfort inside the dog house.

STEP 8 – Roof Panel Installation

Install the roof panels over the completed roof framing, ensuring they are properly aligned and securely fastened. Check that all panel edges are well supported and leave the roof ready for the underlayment and shingles.

STEP 9 – Asphalt Shingles & Ridge Cap

Install the asphalt shingles over the roof panels, working upward in overlapping courses. Finish the roof by installing the ridge cap along the peak to provide a weather-resistant seal.

STEP 10 – Finishes

Apply the selected exterior finishes to the dog house, including exterior-grade paint, dark walnut wood stain, and a natural wood finish protected with exterior polyurethane, spar urethane, or marine varnish. Finish all exposed surfaces for a durable, weather-resistant result.
