My Buying Guide on 20 By 20 Shed
When I decided to invest in a 20 by 20 shed, I quickly realized there’s a lot to consider to get the best value and functionality. Here’s a guide based on my experience that will help you make an informed decision.
Why Choose a 20 by 20 Shed?
For me, the 20 by 20 size hit the sweet spot between spaciousness and manageability. It’s large enough to store my tools, lawn equipment, and even a small workshop area without feeling cramped. If you need a versatile space for storage, hobbies, or even a small office, this size is ideal.
Material Options: Wood, Metal, or Vinyl?
I weighed the pros and cons of different materials before buying:
- Wood: Offers a classic look and can be customized easily. However, it requires regular maintenance like painting and sealing to prevent rot and pests.
- Metal: Very durable and low maintenance. It’s great if you want something sturdy and weather-resistant, but it can get hot in summer and may not blend as well with your yard aesthetics.
- Vinyl: Combines low maintenance with a clean appearance. It’s resistant to rot and pests but may be less sturdy than wood or metal.
In my case, I chose a metal shed because I wanted durability and minimal upkeep.
Foundation and Flooring Considerations
The foundation makes a huge difference in the shed’s longevity. I learned that a concrete slab is the most durable option but can be pricey and time-consuming. Alternatives like gravel beds or pressure-treated wood foundations work too, depending on your budget and ground conditions. For flooring, I opted for treated plywood over concrete to keep the interior warmer and easier to customize.
Doors and Windows: What Works Best?
I looked for wide double doors for easy access to large equipment. Windows were a bonus for natural light and ventilation. If you plan to use the shed as a workspace, I recommend including at least one window and considering lockable doors for security.
Customization and Accessories
I found that adding shelves, workbenches, and hooks made the shed much more functional. Some sheds come with pre-drilled holes for easy installation of accessories. Also, consider gutter systems and vents to protect your shed and keep the air flowing.
Permits and Zoning
Don’t overlook local building codes and permit requirements. Before purchasing, I checked with my local municipality to ensure my shed size and location were compliant. This step can save you headaches later.
Budgeting Tips
My budget included the shed cost, foundation, delivery, and accessories. Always factor in installation costs unless you plan to build it yourself. Comparing prices from different suppliers helped me find the best deal without sacrificing quality.
Final Thoughts
Buying a 20 by 20 shed is a great investment if you plan carefully. Assess your needs, choose the right material, and prepare a solid foundation. With these tips from my experience, I hope your shed purchase will be smooth and satisfying!
