DIY Lean-To Shed Build – 5×12 ft Timelapse Project (Full Guide)

Share on

Project Overview

This project captures the process of building a 5×12 ft lean-to shed in my backyard—from framing the floor to painting the final coat. In this laid-back timelapse, you’ll get a full glimpse of the DIY journey, with real tools, real effort, and zero fancy workshop. Just a backyard, a bunch of wood, and a plan.

Whether you’re a beginner or a weekend builder like me, this is a great starter build for extra outdoor storage—using basic tools and creative workarounds.

Project Snapshot

  • Skill Level: Intermediate

  • Time to Build: ~7 weekends (with breaks)

  • Total Size: 5ft x 12ft

  • Total Cost (est.): ~$2000 on material

Plan Source & Customizations

This lean-to shed was built using a floor plan purchased from iCreatables.com — a great resource for pre-designed shed plans. I picked a plan close to what I had in mind and made a few key tweaks to better suit my needs and layout:

  • Added a third door to improve access and functionality for my space.

  • Included wall sheeting, which the original plans didn’t have — they used only the exterior sheeting directly over the studs.

  • Thanks to the added wall sheeting, I was also able to integrate flashing and a vapor barrier, improving weather resistance and overall durability.

If you’re looking for inspiration or a solid foundation to start your own build, their collection is definitely worth checking out.

Want to save time planning your own shed build? I’ve put together the exact spreadsheet I used to organize materials and estimate the total cost before starting this project. It includes:

Tips from the Build

You don’t need a workshop to start woodworking. I work from my patio using portable benches and compact tools.

Using a track saw was key for clean plywood cuts—super helpful for working solo.

The shed was painted with a basic roller + brush combo. No sprayer needed!
