If you are looking for a project plan for a chair, bench, wall organizer, bed, or cabinet, check out Southern Living project plans. The archive includes plans for indoor and outdoor furniture. Each plan contains a materials list, cutting list, measured drawing, and build instructions. The plans are rated for degree of difficulty to help you decide if you are up to the task.

My particular favorites are the Adirondack chair, Outdoor Daybed, and the Picnic Table (which I think is cool for indoors, too).

Plans can be ordered for $4 and are delivered as a pdf via email.

Finally, I took the time to write down/draw the plan I used to make birdhouses that I posted here some time ago. I made another house from standard pine lumber leftovers and made this drawing. It is based on 3/4″ thick lumber, so you may have to adjust if you use something thicker or thinner. One thing absent from the drawing is a 6″ x 1 1/2″ piece of aluminum flashing that I nailed to the top of the roof to cover the gap between the sides of the roof.

I used pine this time, but I prefer using cedar or something more weather resistant. If you use pine, paint or stain it the exterior with a good exterior oil-based enamel or penetrating oil–preferably a penetrating oil. If you can use cedar, then no finish is necessary.

Unfortunately, I gave the birdhouse away as a gift before I remembered to take a picture of it. But it was similar to these.
