4ft Wide Plastic Sheds
We stock 4 plastic sheds at 4ft wide, starting from £325 for the Palram Voyager 4x3. The range includes two Skylight 4x6 models in grey and tan. The Pent 4x6 adds a sloped roof design. All four use aluminium frames with shatterproof polycarbonate panels. The 4ft width fits narrow side passages, small patios, and tight garden corners.
The Voyager 4x3 is the most compact option for basic tool storage. The Skylight 4x6 adds a translucent roof panel for natural light inside. The Pent 4x6 suits low-height installations against fences or walls. Every model includes a built-in floor, lockable door, and zero-maintenance panels. No painting, no treating, no rot.

About Our 4ft Wide Plastic Sheds
We stock four plastic sheds at 4ft wide, starting from £325 for the Voyager storage unit and up to £479 for the Pent Skylight. These are the narrowest sheds in our range — designed for tight spaces along walls, fences, and in narrow side passages. All four use aluminium frames with polycarbonate panels. Zero maintenance required.
At around 1200mm wide, 4ft sheds fit where nothing else will. We've installed these in alleyways between houses, against garage walls, and on narrow patios. For more width, see our 6ft wide plastic sheds which start from £469. For all compact options, browse our small plastic sheds page.
Why We Chose This Range
"The 4ft range solves a specific problem: where do you put a shed when you don't have room for a shed? The Voyager is a purpose-built lockable storage unit — it's not pretending to be a walk-in shed. The 4x6 Skylight models are genuine small sheds with enough headroom to step inside. And the Pent version with its sloped roof tucks against walls without blocking light from above."
— Matt, Founder of Greenhouse StoresTypes of 4ft Wide Plastic Sheds
Voyager 4x3 Storage Unit
The Voyager 4x3 (£325) is a compact lockable storage unit, not a walk-in shed. It's designed for garden chemicals, hand tools, and smaller items you want kept dry and secure. Front-opening doors give full access to the interior. Ideal for patios, balconies, and small courtyards.
Skylight 4x6 Sheds (Apex & Pent)
The Skylight 4x6 Grey (£459) and Tan (£475) have an apex roof with 2015mm ridge height — enough to step inside. The Pent 4x6 (£479) has a sloped roof that sits neatly against walls. All include lockable doors and a built-in floor.
4ft Wide Plastic Shed Comparison
| Model | Type | Size | Roof Style | Colour | Door Width | Price |
|---|---|---|---|---|---|---|
| Voyager 4x3 | Storage unit | 4ft x 3ft | Apex | Grey | Full front | £325 |
| Skylight 4x6 Grey | Shed | 4ft x 6ft | Apex | Grey | 660mm | £459 |
| Skylight 4x6 Tan | Shed | 4ft x 6ft | Apex | Tan | 660mm | £475 |
| Pent 4x6 Grey | Shed | 4ft x 6ft | Pent | Grey | 1002mm | £479 |
Quick Tip: The Pent 4x6 has a wider door opening (1002mm vs 660mm on the apex models). If you need to store a push mower or wheelbarrow, the pent roof version is the better choice. The wider door makes getting bulky items in and out much easier despite the shed being the same width.

Matt's Pick for 4ft Wide ShedsBest For: A proper shed in a tight space Why I Recommend It: The Skylight 4x6 Grey gives you a genuine walk-in shed at the narrowest width. At 2015mm ridge height, most adults can stand upright inside. The 6ft depth stores more than you'd expect — garden tools, folding chairs, and a push mower. At £459, it's the best value entry into a real plastic shed. Price: £459 |
Matt's Installation Tip: Positioning a 4ft Shed
4ft sheds are narrow enough to fit in side passages and against walls. When placing against a house wall, leave at least 50mm gap for air circulation — this prevents moisture building up between the shed and the wall. The Pent model is specifically designed for wall-side placement, with the slope directing rainwater away from the wall.
For the Voyager storage unit, make sure the ground slopes slightly away from the front doors. This stops rainwater pooling at the entrance. A couple of paving slabs on a thin sand bed is all the base you need for these smaller units.
Our 4ft wide plastic sheds range from £325 for the Voyager storage unit to £479 for the Pent 4x6. All prices include free UK delivery. Every model carries a 10-year warranty and needs zero maintenance — no painting, no staining, no rust treatment.

Frequently Asked Questions
-

-
What's the difference between the Voyager and the Skylight?
The Voyager is a front-access storage unit, not a walk-in shed. You open the front doors and reach in to access stored items. The Skylight 4x6 models are proper sheds with a side door — you can step inside and stand upright at 2015mm ridge height. Choose the Voyager for chemicals and hand tools. Choose the Skylight for items you need to organise on shelves.
-
Should I choose the apex or pent roof?
Choose the pent for wall-side placement or if you need a wider door. The pent roof slopes from front to back, directing rainwater away from the building it sits against. It also has a 1002mm door opening compared to 660mm on the apex model. The apex gives slightly more internal headroom at 2015mm versus 2030mm at the eaves on the pent.
-
Can one person assemble a 4ft plastic shed?
Yes, one person can build any 4ft model in 2–3 hours. The Voyager is the quickest at around 90 minutes. The 4x6 Skylight models take 2–3 hours solo. All panels slot into aluminium channels — no drilling into the panels themselves. A step ladder helps when fitting the roof panels but isn't essential at this size.
-
Do 4ft sheds need planning permission?
No, 4ft sheds fall well within permitted development limits. All four models are under 2.5m in height, which means they can be placed within 2m of a boundary without planning permission in England. They're small enough that even conservation area restrictions rarely apply. Always verify with your local council if in doubt.
-
Can I store a lawnmower in a 4ft shed?
A push mower fits in the 4x6 Skylight and Pent models. The Pent version is easier to manoeuvre a mower into thanks to its 1002mm door opening. The Voyager 4x3 is too small for a mower. For ride-on mower storage, you'll need a minimum of our 8ft wide sheds.
