A quick-start guide to help you plan your space, prep your site, and feel confident before the first board goes up.
Start the Guide →A little prep goes a long way. Here’s what to know before you unpack your kit and get started.
Most sheds take 1–5 days to build, depending on the shed size and your level of experience.
Plan for 1–2 people to complete the project safely, especially when raising walls and setting roof components.
Have your drill, hammer, nail gun, caulk, paint, shingles, and other project materials ready before you begin.
Before choosing your final shed location, check whether your local building department or HOA requires approval for the shed size, style, or placement.
Pick a flat, dry location and leave at least 3–4 feet of clearance around all sides and overhead. Be sure to check local setback requirements, which are often 5–10 feet.
Read the instructions, take inventory of your parts and follow your shed kit step-by-step.

Build a solid base to support your shed.
Assemble walls on your floor, then raise them into place.
Install the rafters and roof decking.
Set windows into openings and add accessories.
Install roofing to manufacturer specifications. Shingles and roofing accessories are optional and sold separately.
Prehung doors are designed for easier installation.
