Keter Newton Plus Sheds

What is the Keter Newton Plus?

It's a grey plastic garden shed made from Keter's Evotech panels. Evotech is a double-wall resin with a wood-textured finish, so you get the look and feel of real wood from the path. Close up it's resin, which means it won't rot, rust, dent or peel, and it needs no preserver every spring. Steel reinforcement in the walls and roof keeps the long sizes rigid.

Every Newton Plus shed shares the same core design:

• Evotech walls in light grey with a dark trim and a shingle-effect roof.
• Two Victorian-style windows plus a full-length skylight, so you can find things without a torch.
• Built-in ventilation to keep air moving and cut down on damp.
• A heavy-duty floor in the kit. Costco's listing says it takes heavy items like a ride-on mower.
• Lockable double doors 1.388m wide and 1.81m high, with a stainless steel locking lever (padlock not included).
• A 15-year warranty on UK sales, as listed by Shedstore and Keter UK.
• Weather resistant panels that are made not to fade in the sun.

The roof height is the same on every model: 1.89m at the eaves and 2.46m at the ridge. That matters for planning, which we cover further down.

Keter Newton Plus sheds: sizes compared

All six are 7'5 (2.30m) from front to back, including the overhang. Only the length changes. Here's the full range as Shedstore sells it, with rough price bands (prices move, so check the cards above for today's figure).

Both versions cost the same and cover the same ground. Inside, the walls take a few centimetres off. Keter lists the 13x7 at 3.90m x 2.01m inside, the 15x7 at 4.53m x 2.01m and the 17x7 at 5.16m x 2.01m, with 2.34m of headroom under the ridge. Keter gives the 13x7 a storage capacity of 16.8 m³.

Apex or reverse apex: one shed, two layouts

The range has a modular design. Keter lets you choose where the doors and the two windows go when you build it, which is why each size appears twice in the grid above.

• Apex (front entry), e.g. 7'5 x 13'. The doors sit in the narrow gable end and the building runs back from them. It's the one for a strip beside the house or along a fence, where you only have about 2.3m of width. Things at the far end are a walk away, so keep what you use least at the back.
• Reverse apex (side entry), e.g. 13' x 7'5. The doors sit in the long side, under the eaves. Everything is a couple of steps from the entrance, which suits a workbench or wheeling a mower in and out. It needs a wider plot with clear space along the front.

Pick by where the path is. Walk up from the narrow end? Go apex. Path along the long side? Go reverse apex. On the 7x7 the two are almost identical, so just choose which way the doors face.

Which size do you need?

Start with what's going in, then add a third for things you'll buy later. As a rough guide:

• 7x7: a push mower, two bikes, hand tools and pots. It's deeper than our 8x6 plastic sheds.
• 9x7: a family store for bikes, a mower and garden furniture cushions over winter.
• 11x7: all of that plus shed shelving down one wall.
• 13x7 and 15x7: room for a ride-on mower or a small workbench, plus storage. The side entry versions make the best home workshops.
• 17x7: the largest, over 12 m², for a store you split into a workshop end and a storage end.

Need more than 2.30m of depth? This range doesn't go deeper. For a squarer large building, the Keter Stronghold comes in 10x8, 10x11 and 10x15, and our 10x8 plastic sheds page covers other brands.

Newton Plus vs other Keter ranges

There are several resin ranges, each built for a different storage job. Here's how they compare at Shedstore.

The Newton Plus costs more than a Factor of similar size. You're paying for the wood-effect walls, the skylight and the heavier floor. If you want resin that won't look like plastic from the house, it's the range to pick.

Is the Keter Newton Plus any good?

Here's the honest view, from the specifications and what owners tend to raise.

What it does well

• It looks like timber, with a real grain texture and a grey that won't need repainting.
• Almost no maintenance beyond a wash down, in any weather. Resin needs no treating.
• Light inside. The skylight and two windows make it usable as a workshop on a dull day.
• Strong for resin. Keter rates the roof for a snow load of 125 kg/m², and the steel-reinforced double-wall panels resist knocks.
• A floor is included, which many wooden sheds charge extra for. See our plastic sheds with floors for more.

What to watch for

• It needs a properly level base. Resin doesn't flex into shape like timber, so the doors won't line up on a twisted one.
• It's a big build. The large models ship in several boxes at a weight of over 200kg, so plan for two people and a full day.
• Condensation can form on cold mornings, as with any plastic or metal building. Keep the vents clear.
• It's dearer than plainer resin and many timber sheds of the same size, though there's no yearly treatment to buy.

Base and assembly

Keter says a foundation is required. It must be flat, level and a little bigger than the floor. The maker's minimum foundation for the long models is 4.05m x 2.16m for the 13x7, 4.68m x 2.16m for the 15x7 and 5.31m x 2.16m for the 17x7. Good choices:

• A concrete slab - the most solid option, and you can screw the building down.
• Paving slabs laid level on a sand and cement bed.
• A plastic grid filled with gravel - see our shed bases.
• A timber frame on adjustable feet for sloping ground - see adjustable shed bases.

Never build straight onto grass or soil. The ground moves, the floor twists and the doors stop closing. Anchor it down too, as wind can shift a long resin building with nothing holding it.

Assembly tips

The tools listed are a screwdriver and an electric screwdriver. Costco quotes 7-9 hours for two people on its 15ft version. Lay the panels out first, check the parts list, and pick a still, dry day, as big roof panels catch the wind.

Delivery from Shedstore

Shedstore lists free delivery to most UK postcodes. It doesn't deliver to the Isle of Wight, Isle of Man, Isles of Scilly, Northern Ireland, the Channel Islands, the Scottish islands or some Highland postcodes. Your Newton Plus comes flat-packed by courier, direct from the maker, and the courier rings to book a date. Shedstore says to contact it if you haven't heard by the end of 10 working days.

Do you need planning permission?

Usually not. In England most garden sheds count as permitted development if they meet the rules in the Planning Portal guide to outbuildings. One rule matters here: a building within 2m of a boundary must be no more than 2.5m high.

At 2.46m to the ridge, the Newton Plus sits just under that limit. Height is measured from the highest ground next to the building, so a raised base can push it over. Keep the base low near a fence. The government's permitted development technical guidance has the detail. Wales, Scotland and Northern Ireland have their own rules, and listed buildings and conservation areas have tighter limits.

Kitting it out

• Security: the doors take a padlock but one isn't supplied. Add a closed-shackle lock and ground anchors from our shed security range.
• Light: the skylight covers the day. For winter evenings, battery or solar shed lighting needs no wiring.
• Storage: Add shelves for extra storage - any freestanding unit will go under the 1.89m eaves.
• Bikes: the 1.388m doors take bikes easily. For bikes only, our plastic bike sheds cost less.

Keter Newton Plus FAQs

What sizes does the Keter Newton Plus come in?

Six, all 7'5 (2.30m) deep: 7x7, 9x7, 11x7, 13x7, 15x7 and 17x7. Each is sold front entry (apex) and side entry (reverse apex), so there are 12 versions.

Does it come with a floor?

Yes, every kit includes a heavy-duty floor. You still need a flat, level base under it.

How tall is it?

2.46m to the ridge and 1.89m at the eaves on every model, with about 2.34m of headroom in the middle.

What warranty does it have?

Shedstore and Keter UK list a 15-year warranty, which you register with Keter. Some other stockists quote 10 years, so check the terms where you buy.

Can I move the door later?

The door and window positions are fixed when you build. Moving them means taking panels apart, so settle the layout first.

Is it the same as the Keter Newton?

Newton Plus is the range Keter sells in the UK now, and many people search for it as the Keter Newton shed. Replacing an older one? Check the size first, as every Newton Plus is 2.30m deep. Keter's 13x7.5ft product page lists the full specifications.
