For those without much experience in construction and carpentry, or just need a refresher, sometimes the basics need to be made concise and clear.  If you've already considered your foundation type and picked out what materials you'll be using to build your playhouse, it's now time to review how these components should be fitted together. This framing outline has been designed to help guide you through the process of how to nail and screw lumber together. The methods for attaching lumber described below do follow most residential construction codes, though it's recommend you check with your local requirements.Note that all the playhouse plans include a lumber list. Using this list and the fastener instructions below, the near exact hardware count and price for every plan can be extrapolated.   Recommended Types of Nails, Screws and Bolts When building your playhouse, use 3” decking screws or 16d nails to secure all 2x material when building walls, joists, rafters and ladders. Use 2” decking screws or 12d ring shank nails for securing all 5/4” x 6” material. For posts, use ½” galvanized carriage bolts with a washer and lock washer. Screws generally have more holding power compared to an equally sized nail and are much faster to remove if a mistake is made. Because of this, screws are recommend over nails for your playhouse project. Framing Walls, Joists, Rafters & Ladders When it comes to fastening framing together in the form of walls, joists and other scenarios,  where the ends of 2x lumber is prone to cupping or twisting, the first and last fasteners are the most important as they are doing most of the work keeping those pieces in place to prevent warping. In all cases, keep the nails or screws centered (¾” from the edges), and keep first and last fastener a ½” from the top and bottom of the lumber. In the cast of a 2x4, there will only be a top and bottom fastener, but in the case of a 2x6 or something larger, there will be some in the center. Basically for ever
