16'x20' Workshop Start to Finish around $20,000

Introduction

This tutorial provides a comprehensive guide to building a 16'x20' workshop, inspired by a project completed by Kens Karpentry. The estimated cost for this project is around $20,000, and it includes all critical steps from laying the foundation to finishing touches. This guide is useful for DIY enthusiasts and anyone looking to create a functional workshop space.

Step 1: Preparing the Foundation

• Set Up Forms: Create forms using wood to outline the area where the concrete will be poured.
• Install Rebar: Add half-inch rebar in a two-foot by two-foot grid pattern to reinforce the concrete.
• Pour Concrete: Use 3000 psi concrete, ensuring it's evenly distributed.
• Level the Concrete: Rake out the concrete and check for flatness, aiming for a surface as smooth as a tabletop.

Step 2: Smoothing the Concrete Surface

• Use a Power Trowel: After initial setting, run a power trowel over the surface to achieve a smooth finish.
• Bull Float Technique: Employ a bull float with adjustable angles to avoid bunching the concrete while smoothing.

Step 3: Framing the Walls

• Construct Wall Frames: Use 2x4 lumber for wall framing, spacing studs 16 inches apart.
• Secure the Sill Plate: Install a pressure-treated sill plate at the bottom of the wall frames and anchor it with wedge anchor bolts.
• Nail the Studs: Use three nails per stud for added stability during transportation. Make sure nails are not directly across from each other to avoid misfires.

Step 4: Adding Sheathing

• Install OSB Board: Use 7/16” OSB boards for wall sheathing, staggering the joints for structural integrity.
• Ensure Leveling: Constantly check for level as you install the OSB.

Step 5: Roofing the Workshop

• Install Roof Plywood: Begin by covering the gable ends with plywood.
• Complete the Roof Structure: Set the roof frame to ensure it aligns with the workshop design.

Step 6: Siding and Exterior Finishing

• Begin Siding Installation: Use vinyl siding, leaving a quarter-inch gap for expansion.
• Secure Panels: Nail panels loosely to allow for movement, ensuring they lock into place without being too tight.
• Attach Soffits and Fascia: Install vinyl soffits and metal fascia to complete the exterior look.

Step 7: Final Touches and Interior Setup

• Add Windows and Doors: Install a 9x7 garage door and two windows for natural light and ventilation.
• Interior Setup: Create a functional interior space for crafts or storage, ensuring there’s enough room for tools and a workspace.

Conclusion

Building a 16'x20' workshop can be accomplished with careful planning and execution. Key steps include laying a solid foundation, framing walls, roofing, and finishing with siding. By following these steps, you can create a functional space tailored to your needs. Consider planning your layout and storage solutions to maximize the utility of your new workshop. Happy building!
