Prepare the site - Choose a well-drained position and check local setbacks, permits, wind, snow and frost requirements. Have underground utilities located before digging. - Confirm the footing, anchoring and structural connection design for the site before buying materials. The drawings locate supports but do not specify footing sizes or load capacities. - Mark a rectangle 240 x 96 in along the outside timber faces. Adjust the corners until both diagonals measure 258 1/2 in and the sides match. - Mark the henhouse at the first 72 in of the length. Leave room outside the frame for the 12 in buried mesh return, roof overhangs, nest box and working access. - Establish a level height reference and mark the post centers shown in the site layout. Keep surface water draining away from the coop. Check: The footprint measures 240 x 96 in, both diagonals measure 258 1/2 in, and the support locations and site requirements are confirmed. ![Square the site layout and mark the post centers before setting the frame.](https://diyplans.org/media/packages/0b4c349f9f9e5a618f31b3c8a760dd900fe8b46a89b674d97aec8c30e588bb4d/image-step-01/step-01.png?brand=1) Square the site layout and mark the post centers before setting the frame. Reference drawings: - [Floor and run plan](https://diyplans.org/media/packages/0b4c349f9f9e5a618f31b3c8a760dd900fe8b46a89b674d97aec8c30e588bb4d/image-plan/plan.png?brand=1) ### 2. Set the base frame - Select ground-contact 4x6 timbers and compatible corrosion-resistant connectors. Cut the perimeter pieces from the stock and cut lists. - Set the perimeter on the prepared supports with the timber tops 5 1/2 in above the finished-ground reference. Keep the outside frame 240 x 96 in. - Join the timbers at the butt joints shown in the plan. Recheck both diagonals before fixing the frame to the site-designed supports. - Provide anchored bearing beneath every roof post. Keep mesh fasteners and ground staples separate from the structural anchors. Check: The perimeter is level and square, with anchored bearing at every roof post. ![Set the perimeter timbers to the ground and height references.](https://diyplans.org/media/packages/0b4c349f9f9e5a618f31b3c8a760dd900fe8b46a89b674d97aec8c30e588bb4d/image-step-02/step-02.png?brand=1) Set the perimeter timbers to the ground and height references. ### 3. Close the buried perimeter - Use 1/2 in welded hardware cloth, 19 gauge and galvanized after welding. Excavate the perimeter trench without undermining the foundation supports. - Form the 48 in wide wall strips into an 18 in above-ground leg, an 18 in buried leg and a 12 in outward return. Keep at least 6 in of secured overlap with the wall enclosure. - Continue the underground barrier beneath the gate. At that opening, trim the above-ground leg to 6 in and secure it beneath the fixed threshold. - Overlap adjoining strips and close every corner with the separate patches. Clamp or fasten the seams so an animal cannot pull them apart. - Inspect the full perimeter, gate crossing and every foundation interface before backfilling. Protect the mesh from damage while completing the frame. Check: The buried mesh forms a continuous enclosure beneath the walls and gate, with secured seams and corners before backfilling. ![Close the buried barrier around all sides and beneath the gate.](https://diyplans.org/media/packages/0b4c349f9f9e5a618f31b3c8a760dd900fe8b46a89b674d97aec8c30e588bb4d/image-step-03/step-03.png?brand=1) Close the buried barrier around all sides and beneath the gate. ![Keep the buried leg and outward return continuous; secure the enclosure overlap.](https://diyplans.org/media/packages/0b4c349f9f9e5a618f31b3c8a760dd900fe8b46a89b674d97aec8c30e588bb4d/image-barrier/barrier.png?brand=1) Keep the buried leg and outward return continuous; secure the enclosure overlap. ### 4. Raise the posts and beams - Cut the 4x4 posts and position them at the marked stations. Clamp temporary braces in place while bringing each post plumb. - Fit the paired 2x6 top beams with their top faces 96 in above the ground reference. Center every beam butt joint over its supporting post. - Fit the permanent knee braces shown in the framing view. Use the selected structural connectors and their specified fasteners. - Recheck post plumb, beam level and both frame diagonals before tightening the connections. Keep temporary bracing until the frame is stable. Check: The posts are plumb, beam tops are level at 96 in, and the selected bracing and connections are fitted. ![Raise and brace the posts, paired beams and permanent knee braces.](https://diyplans.org/media/packages/0b4c349f9f9e5a618f31b3c8a760dd900fe8b46a89b674d97aec8c30e588bb4d/image-step-04/step-04.png?brand=1) Raise and brace the posts, paired beams and permanent knee braces.

Frame and deck the raised floor - Cut the 2x6 floor bands and joists. Set every joist top at 31 1/4 in so the 3/4 in deck finishes at 32 in. - Mark the near joist faces from the outside henhouse end at 3 1/2, 19 1/2, 35 1/2, 47 1/4, 51 1/2 and 67 in. Fit the seam blocking shown in the floor layout. - Cut two 48 x 48 in and two 24 x 48 in floor panels. Mark and cut the 3 1/2 x 3 1/2 in outer post notches shown on the panel layout. - Dry-fit all four panels. Check the post locations and the panel manufacturer's edge-gap requirements before fastening to the bands, joists and blocking. - Seal exposed panel edges with a finish suitable for this use. Keep the deck flat and the finished floor at the 32 in reference.
