8ft Wide Plastic Sheds
We stock 2 plastic sheds at 8ft wide: the Palram Canopia Rubicon 8x8 at £989 and the 8x10 at £1,375. Both are finished in dark grey with an aluminium structural frame and 10mm twin-wall polycarbonate panels. The Rubicon includes gable apex vents for airflow and a tough built-in poly floor. It handles heavy garden equipment without cracking.
The 8x8 gives you 64 sq ft of usable storage. Step up to the 8x10 for 80 sq ft. Both models feature double lockable doors wide enough for a ride-on mower or large wheelbarrow. No painting, no treating, no rot. Palram include a 10-year warranty on every Rubicon shed.
About Our 8ft Wide Plastic Sheds
We stock two 8ft wide plastic sheds, both from the Palram Canopia Rubicon range. The Rubicon 8x8 starts at £989 and the Rubicon 8x10 is £1,375. Both feature 10mm twin-wall polycarbonate panels in dark grey on an aluminium frame. No painting, no treating, no rust.
The Rubicon sits between our 6ft wide Skylight range and the 11ft wide Yukon range. At 2290mm wide, it offers genuine walk-in storage without dominating a medium-sized garden. We've assembled both models and the 10mm panels feel noticeably more solid than the standard Skylight panels.
Why We Chose This Range
"The Rubicon is the mid-range option I recommend most often. It's wider than the Skylight at 8ft but doesn't need the serious base preparation of an 11ft Yukon. The 10mm twin-wall polycarbonate is a step up from the standard panels — you can feel the difference in rigidity when you push against the wall. For customers who want more than a 6ft shed but don't have space for an 11ft Yukon, this is the answer."

Rubicon 8x8
The square 8x8 (£989) gives you 5.2m² of floor space. It's 2290mm wide and 2290mm deep with a 2350mm ridge height. The double doors open to 1295mm — wide enough for a standard push mower. Ideal for garden tool storage, bikes, and outdoor furniture over winter.
Rubicon 8x10
The 8x10 (£1,375) adds 750mm of extra depth for 7.0m² total. That extra space makes a real difference — you can fit shelving along the back wall and still have clear floor space in front. Same 2350mm ridge height and 1295mm door opening as the 8x8.
8ft Wide Plastic Shed Comparison
| Model | Width | Depth | Ridge Height | Floor Area | Door Opening | Panels | Price |
|---|---|---|---|---|---|---|---|
| Rubicon 8x8 | 2290mm | 2290mm | 2350mm | 5.2m² | 1295 x 1780mm | 10mm twin-wall | £989 |
| Rubicon 8x10 | 2290mm | 3040mm | 2350mm | 7.0m² | 1295 x 1780mm | 10mm twin-wall | £1,375 |
Quick Tip: The 8x10 costs £386 more than the 8x8 but gives you 35% more floor space. That extra 750mm of depth transforms the shed from tight storage to comfortable walk-in space. From our experience, most customers who start looking at the 8x8 end up buying the 8x10.

Matt's Pick for 8ft Wide ShedsBest For: Walk-in storage with room to organise Why I Recommend It: The extra 2ft of depth on the 8x10 makes a bigger difference than the numbers suggest. I've fitted both models back to back, and the 8x10 feels like a proper room rather than a cupboard. You can stand inside, close the doors, and still move around your equipment. Price: £1,375 |
Matt's Installation Tip: Rubicon Base Requirements
The Rubicon 8ft range needs a flat, solid base. We recommend paving slabs on a compacted hardcore sub-base for both models. The base should be exactly 2290mm x 2290mm for the 8x8 or 2290mm x 3040mm for the 8x10 — the shed sits directly on the edges with no overhang.
Check your base is level across both diagonals before you start building. If the diagonals differ by more than 10mm, the doors won't close properly. We use a long spirit level and a straight edge across the full width. Spending an extra hour on the base saves hours of frustration later.
Both 8ft wide Rubicon sheds include free UK delivery, a heavy-duty built-in floor, and a 10-year warranty. They resist 75mph winds and won't rot, rust, or need painting. The dark grey colour blends well against fences and garden boundaries.

Frequently Asked Questions
-
How much do 8ft wide plastic sheds cost?
The Rubicon 8x8 costs £989 and the 8x10 costs £1,375. Both prices include free UK delivery and a built-in heavy-duty floor. The 10mm twin-wall polycarbonate panels and aluminium frame are included — no extras to buy for a complete, weatherproof shed.
-
What's the difference between Rubicon and Skylight sheds?
Rubicon uses thicker 10mm twin-wall panels compared to Skylight's standard panels. The Rubicon is only available in dark grey and starts at 8ft wide, while the Skylight comes in grey and tan in 4ft and 6ft widths. The Rubicon feels more solid and provides better insulation due to the twin-wall construction. Both ranges use aluminium frames and require zero maintenance.
-
Can two people assemble a Rubicon 8ft shed?
Yes, two people can build either model in 4–6 hours. The panels slide into the aluminium frame channels. You'll need a drill for the base anchors and a step ladder for the roof panels. We recommend assembling the floor frame first, checking it's perfectly level, then building up the walls before fitting the roof. No specialist tools are needed.
-
Should I choose the 8x8 or the 8x10?
Choose the 8x10 if your garden has the space — the extra depth is worth it. The 8x8 gives 5.2m² which suits basic tool and bike storage. The 8x10 provides 7.0m² — enough for shelving along the back wall and clear floor space in front. The price difference of around £386 buys 35% more usable area.
-
Are Rubicon sheds waterproof?
Yes, the 10mm twin-wall panels and sealed aluminium frame keep water out. The panels slot into channels that prevent rain ingress at the joints. The floor sits on a raised frame that keeps moisture from wicking up from the ground. We've tested both models in heavy rain and found no leaks. The gable vents have screens that allow airflow while blocking rain.
-
Do I need planning permission for an 8ft wide shed?
Generally no, under permitted development rules in England. The Rubicon's 2350mm ridge height is under the 2.5m limit for buildings within 2m of a boundary. This means you can place it close to a fence without planning permission in most cases. Check with your local authority if you're in a conservation area or your property has specific restrictions.
