Here's how to find the best shed for your garden

How big should my shed be?


Think about your big items and add up the space they take up. Make sure there's space left for moving things around.


You'll need enough room for a workbench and some shelves, with space left over for getting in and out.

A bit of both

You'll have to go big. If you don't have space, consider a separate garden storage solution to go with it.

The different garden shed types

Wooden sheds


- Beautiful natural finish

- Stain and paint any shade you like

- Different panel designs available


- Vulnerable to rot and mould

- Wood needs re-treating annually

- Easier to damage

Metal Sheds


- Toughest and most durable

- Full weather and water protection

- Most secure

- More door options


- Harder to decorate or customise

- Harder to build

- Condensation (check for ventilation)

- Rust (check if it's rust proof)

Plastic sheds


- Tough and durable

- Hard to damage (some deflect damage)

- Very low maintenance

- Easy to assemble and disassemble (take it with you when you move)


- Hard to customise

- Could warp in sunlight (check for protection)

- Lightweight (needs a strong anchor)

What sort of shed base do I need?

You must have a shed base to secure the shed to the ground and stop it moving.

You can buy a pre-built base or create your own with concrete or cement. A base should be the same size or a few cms larger than your shed.

You'll also need to anchor your shed to the base. An anchor kit may come with a base, or be sold separately.

Where to put your shed...

Think about doors and windows

Where are they placed? Is there room to open them? Will you get a view of the garden fence?

Pick a flat, level spot

If it's on a slope, everything inside will fall to the back and tip it over.

Choose a dry spot

If an area is prone to flooding, your shed could sink.

Close to your driveway?

Better if you want to get a mower to your front garden, or bikes on the road.

Close to your back door?

You've got less far to walk, and it's easier to wire to the mains.

What about trees?

Trees are great for shade, but falling branches could cause damage.

Choosing shed doors



They don't need much space to open, but it's harder to move stuff in and out. It's handy if they can fold back.

Double doors

It's easy to move things out when you have big doors, but you'll need room to open them up.

Sliding doors

They take up less space, but aren't available on wooden sheds.

Different shed roof types


Pent roofs

They slope in one direction. There's more headroom, but rain flows down to one spot.

Apex roofs

A triangle top that directs rain down both sides. There's more headroom in the middle, but less at the sides.

The different types of wooden shed



The wood panels overlap each other.


Tongue and groove sheds

Panels join together, preventing moisture from getting through.



Similar to tongue and groove. Water runs away from the join to prevent distortion over time.

Do I need to paint my wooden shed?

Sheds need protecting against weather damage. Use wood treatment for the natural look, or choose exterior paint for a splash of colour.

You'll need to repaint every so often to maintain the protection. How often depends on the paint and the wood's original treatment.

The different treatments for wooden sheds

Dip dried

Standard wood treatment - you'll need to treat your shed's wood annually.

Pressure dried

Wood treatment that's deep-basted into the wood, so it lasts longer and needs less frequent re-treating.

The different roof felts for wooden sheds


Mineral felt

Tougher and more durable than sand felt. The finish looks like lots of tiny pebbles.
