These owl house plans are designed for a Screech Owl or a Boreal Owl. These two owl species require an owl house that has an 8" x 8" floor, an inside height of 12-15 inches and an entrance hole that is 3 inches in diameter.
The owl house attached to the tree (below) is the finished product. I attached it to the tree by screwing a piece of 1x2 to the back of the house. I cut the 1x2 so that it extends about 2 inches past the top and the bottom of the owl house. I used heavy duty wire ties to affix the house to the tree.
Please read the complete instructions before you begin building this owl house. You may choose to use different for your own owl house plans.
A single 1" x 8" plank that is 8 feet long is all you need for the bottom, front, back, sides, and roof. A typical rough cut cedar 1x8 measures approximately 3/4 x 7 3/4 (depending on the mill). I added some custom 1x1 trim on the corners of the house to make the inside dimensions a little bigger and to add some style to the owl house. Here is the complete material list:
|Western Red Cedar||1" x 8" x 8'||1|
|Western Red Cedar||2" x 2" x 6'||1|
|Western Red Cedar (for mounting)||1" x 2" x 20"||1|
|16 Gauge Galvanized Finish Nails||2"||50 (approx.)|
|Galvanized Wood Screws||1 1/2"||10 (approx.)|
From the 8' cedar plank, cut the bottom, sides, ends, and top pieces to the lengths indicated in the diagrams on this page. Using a table saw, rip the 2x2 to make 1" square stock (6' long).
To cut the roof angle, measure to the center on one of the end pieces and make a mark on the top. From that mark, take a square and mark a 45 degree angle on both edges of the board (see below). Cut the roof angle on the front panel, then use it as a template to layout the back panel.
Cut the four corner pieces from the custom 1x1 so that, when nailed to the front and back pieces, they are flush on the bottom (90 degree) and top (45 degrees). Attach the four corners to the front and back pieces. See the diagrams above and below.
The entrance hole is 3" in diameter. You can use any method you want to draw the circle. I found a can in my garage that had a 3" base and positioned it up at the top of the front panel and drew a circle around it with a carpenter's pencil. If you have a 3" hole saw, you can use it to cut the hole. If you don't, you can use a jig saw or a coping saw.
Attach the front and back pieces to the bottom piece and one of the side pieces, using the 2" nails. Attach the remaining side using the 1 1/2" wood screws, one on each side about an inch from the top. This will act as a hinge so that you can clean the nest box from time to time. (see below)
Use another screw to secure the bottom of the side (hatch) to the bottom piece (not shown). Pre-drill the hole for the screw to prevent splitting the wood.
Attach the roof pieces as shown in the diagrams below. Note that at the bottom-left of the drawing on the right, there is a small piece of wood sticking out. This is a spacer for the 1" x 2" mounting board - the thickness of it matches the overhang on the back side of the roof.
When you attach the mounting board, the spacer keeps the owl house level. Use 4 of the 1 1/2 screws to attach the mounting board to the back of the owl house.
The mounting board is included in these owl house plans, but it is completely optional. There are many other ways to mount this own house. If you have some good ideas for mounting options, please let me know by using the contact us form.
