We will suggest you select the simple Birdhouse if you are new at woodworking but be sure to select its design with respect to the place where you are going to hang/place it. One of our simple Birdhouse tutorials will help you building one. We have managed to include a source tutorial below that will help you to understand illustrates and the instruction to building a simple Birdhouse.
To inset the aprons 3/4" from the outer surface of the legs I made a spacer from 2 pieces of plywood. This little jig made it easy to keep the distances uniform and also secure the apron to the leg while fastening. Pic 3 illustrates how the jig, apron and leg are clamped together for fastening. Each apron end is held by three 2 1/2" pocket screws. The pocket holes were made using a Kreg pocket hole jig. I assembled the short ends first and then the rest of the table base making sure the kerf (for clips) was along the top edge. Since this is a long table I also added a cross piece in the middle of the table using pocket screws.
