Frequently Asked Questions

What are the most popular shed styles?

The most popular shed styles include gable sheds with their classic roofs, barn sheds with their gambrel roofs and ample headspace, lean-to sheds with their simple single-sloped roofs, modern sheds with their sleek and minimalist exteriors, and craftsman sheds with their smooth roof lines and charming trim accents.

What size shed do I need?

To determine the right shed size, consider what you'll be storing, the available space in your backyard, and whether you need room for future expansion. Measure your backyard carefully and think about how the shed will fit into the overall landscape.

What are the different types of shed foundations?

Common shed foundation types include concrete slabs, gravel pads, concrete blocks with wooden skids, and poured concrete footers with wooden beams. The best foundation for your shed will depend on factors like the size and style of the shed, local climate and soil conditions, and your budget.

What should I look for in a shed plan?

A good shed plan should include clear and detailed instructions with diagrams and illustrations, a comprehensive materials list with quantities and specifications, information on the required foundation and framing, and access to reliable customer support. It should also specify the necessary tools and materials, provide guidance on shed location and space planning, and offer options for customization and security features.

Can I build the shed myself using these plans?

Not only will this allow you to complete the project more quickly, but it will also make the process much safer.

What tools do I need to build the shed?

Essential tools include:

Circular saw
Drill/driver
Level
Measuring tape
Hammer
Speed square

A complete tool list comes with each plan.

What exterior materials are best for my shed?

LP SmartSide siding offers durability with a 50-year warranty and engineered wood construction. Vinyl siding provides low maintenance and weather resistance at an affordable price point. Cedar siding delivers natural beauty and insect resistance but comes at a premium cost. Metal siding ensures longevity and fire resistance with a modern aesthetic. Fiber cement combines extreme durability and fire resistance while maintaining a wood-like appearance.

How long does it take to build a shed?

A small shed up to 8x8 typically takes one to two days to complete. Medium-sized sheds between 8x12 and 10x12 require two to three days. Larger sheds of 12x16 or more need three to five days for construction. Site preparation and foundation installation usually add an additional day to the timeline.
