What Exactly Is a 20×10 Garden Shed?

Before we get started, it’s important we all have a common understanding of what a 20×10 garden shed is. A 20×10 garden shed is a storage shed that is 20 feet long and 10 feet wide.

The 20×10 measurements refer to the outside dimensions, with the inside dimensions being slightly smaller (often by an inch or two on all sides).

It should also be noted that with a 20×10 garden shed, you’re looking at 200 square feet of storage space. That’s a lot of space! It’s enough to:

Store tools and equipment for your garden.
Store lawnmowers and other big equipment.
Store seasonal decorations or outdoor furniture.
Store seasonal sports equipment like bicycles or skis.

But, those are all basic uses of a 20×10 garden shed.

If we’re going to be clear on the basics, we need to understand the biggest problem with garden sheds and 20×10 garden sheds in particular: the features.

As we mentioned in the introduction, most garden sheds on the market will have completely different features. Some are bound to be great features. Other features will be completely useless or frustrating to use.

Unless you have the necessary knowledge, you might end up with:

Wasted space
Bad ventilation
Moisture or water damage
Sheds that fall apart after only a couple of seasons.

The global outdoor shed market is currently valued at around $6.6 billion and set to expand by more than 50% to over $10.7 billion by 2030, driven by homeowners demanding better functionality.

So, as you can see, these things are nothing to take lightly.

When looking at a 20ft x 10ft shed or any other kind of garden shed, we always recommend starting with the bare bones of what you are looking for in terms of actual features.

It’s only when you have a firm handle on what makes a functional 20×10 garden shed that you can start adding more advanced features to what is already a solid and good product. With that in mind, let’s take a look at the functional features every 20×10 garden shed must have.

Structural Features to Look for in 20×10 Garden Sheds

Table of Contents

Solid foundation & floor

Foundation is king in the world of garden sheds. Without a solid base and floor, your garden shed is almost certain to start to fall apart quickly. Look for:

Pressure-treated timber floors that will last longer without rotting
Raised bases and floor boards to prevent moisture damage
Tongue and groove flooring for extra strength and stability
Adequately supported and spaced bearers

Wall construction that lasts

Wall thickness is more important than most people realize. Thin walls are a non-starter. They will not hold up against the elements, provide much-needed insulation or keep your belongings safe.

Look for wall cladding that is at least 12mm tongue and groove, shiplap or overlap for durability. Also make sure that:

The timber is treated for rot resistance.
There are reinforced corners and joinery.

Roof design & materials

Roofing is what truly protects the inside of a garden shed from the elements. Look for sheds that have:

Apex or pent roof design for water runoff
Felt or mineral felt roofing covering.
Adequate overhang to protect walls from water.
Strong roof boards that sit underneath the felt.

Smart Storage Solutions for 20×10 Garden Sheds

Built-in shelving & racking

Empty space is wasted space in the world of 20×10 garden sheds. If there is space, there should be something built-in to maximize that space and make it useful.

Look for garden sheds with built-in features such as:

Wall-mounted shelving or shelving units.
Corner shelving for odd-shaped spaces.
Adjustable shelving heights.
Heavy-duty brackets that won’t bend under weight.

Tool hanging systems

Vertical storage is a game-changer for 20×10 garden sheds. The best ones will feature:

Pegboard walls or other hanging storage.
Tool hooks and hangers.
Magnetic strips for small metal tools.
Overhead hanging storage racks.

Workbench space

A surprising number of people use their 20×10 garden shed as a mini workshop of some sort. A built-in or dedicated workbench area is a huge value-add.

Look for:

A solid bench that can support heavy work.
Comfortable working height.
Good lighting.

Security & Weather Protection in 20×10 Garden Sheds

Windows & ventilation

Moisture buildup is a big enemy of garden sheds. Without proper ventilation, things start to rust and mold, causing damage and expense.

Look for sheds with:

Windows for natural light and ventilation.
Adjustable roof vents near the apex for hot months.
Styrene or safety glass in windows.
Optional window bars or security screens.

Door quality & design

A door is the most used part of a garden shed. Doors need to be made well and with a good design in mind. Look for:

Double doors for easier access with large items.
Strong hinges that won’t sag over time.
Weather-resistant seals and door weatherboarding.
Reinforced frames.
Options for padlock or built-in locks.

Weatherproofing treatments

Raw timber will not last long in the elements. Look for sheds that come with:

Factory treatment against rot and insects.
Water-resistant exterior coating.
UV-resistant exterior finishes to prevent fading.
Regular maintenance schedules (check often).

Bonus Features for a Better 20×10 Garden Shed

Electrical installation

Adding power to a 20×10 garden shed opens up a whole world of possibilities. A power source means you can add:

Lighting for working after dark.
Power outlets for tools.
Heating in colder months.
Security systems.

Insulation options

Insulated sheds are not just for year-round use. Insulation will protect your stored items from temperature extremes, make it more comfortable for working, prevent condensation issues and soundproof.

Insulation is especially important for those planning on using the 20×10 garden shed as a workshop or hobby space.

Final Thoughts

A 20×10 garden shed is much more than just a glorified storage box. The right combination of features can turn a basic storage space into a real gem.

In fact, we might even go so far as to call it a functional workspace. In many ways, the idea of a garden shed acting as a workspace is now common.

The garden shed market as a whole is predicted to grow from its current $6.6 billion to over $10.7 billion by 2030, as homeowners more and more appreciate the value of a well-designed outdoor storage option.

A 20×10 garden shed offers an ideal size for many residential properties, providing a significant amount of storage space without taking up too much yard space.

By prioritizing these essential features, you can ensure that your 20×10 garden shed becomes more than just an add-on to your property. It can become a highly functional space that meets your storage needs while also offering much more than basic storage.

In particular, look for garden sheds that offer:

Solid construction with quality materials
A proper foundation and weatherproofing.
Smart internal storage solutions.
Good ventilation and natural light.
Secure doors, with options for power supply.

Then you’ll never go wrong with your next garden shed purchase.
