Specification Description Watch Video Reviews Delivery / Returns Aftercare Important Info

Delivery on this building is 10 working days to most addresses.

After you have placed your order one of our team will contact you directly to arrange a suitable delivery date.

Important - Delivery is kerb side only, though at the driver's discretion they may be able to help you lift the building to a more suitable location outside your property. If you need to transport the building through your house, then you will need to make your own arrangements prior to delivery to do this, as our drivers are not insured to enter your house.

The Customer or Friend/Neighbour will need to be present to sign for the delivery. We cannot leave the item without a signature.

We want you to enjoy the use of your new garden building for many years. To give you the best chance of doing so, your product needs protecting at the start and maintained during its life. If you're planning a DIY project, please read our Self-Installation & How to Build a Shed advice pages before you start.


All long-lasting garden buildings will have been built on a solid and level base, either concrete, slabs, a wooden frame or ground level bearers. A flat, level base is essential, for more information go to our How to Build a Shed Base guide.

If your garden building is not level and square when built, it will twist and warp with the natural movement of the wood. The first signs of this are when the doors or windows stop opening and closing properly. You may get issues with the roof and potential gaps in the panels which will allow water in, there may be flex in the floor and probably creaking. Check your base is level in both directions and adjust prior to the build. It will be really difficult to adjust afterwards.


Our styrene windows are protected using a clear film which will need to be removed after you've installed the building.

All Waltons shed windows are designed to fit well, but over time and with the movement of wood, small gaps can appear. Help to prevent this by sealing your windows with a silicone sealant. You can do this either when you build your shed, or add it to an existing one. We've created this video Protect Your Shed - Silicone Window Sealant for guidance.

We've also created these handy Maintenance Guides to help you make the most out of your building, for years to come. Should you require any further advice, you can contact our Customer Service Team on 0800 029 1000 and select Option 3.

Our dip treated buildings, once installed, will need treating as soon as possible and on an annual basis in order to receive the 10 year anti rot guarantee*. The building also includes a 1 year manufacturers guarantee* as standard.

Dip Treated Buildings

  • Our buildings are supplied flat packed as DIY kits with full instructions.
  • It is the customer's responsibility to follow the instructions outlined in Aftercare.
  • All of our buildings are delivered unpainted. The buildings are dressed for display, we don't supply any accessories or shelves featured within the product images.
  • Our factory applied Dip Treatment may differ in shade between components as it is simply a basecoat.
  • Exact product dimensions are supplied on the listing as we do round off the main size of the building in order to make it easier for customers to find, so please be sure to check the item's specific measurements carefully.
  • All measurements refer to the exterior of the building which includes the roof overhang unless stated otherwise.
  • Our styrene windows are protected using a clear film which will need to be removed after you've installed the building.
  • Delivery times highlighted with an asterisk (*) refer to working days.

10 Year Anti-Rot Guarantee

Our Dip Treated Garden Buildings come with a 10 year anti rot guarantee. Anti-rot protection guards against fungal decay. The guarantee does not cover movement, twisting, warping or splitting of timber products over time.

During manufacture we apply a water based treatment which protects against fungal and insect attack. This treatment lasts approximately 3 months and will require a preservative top coat application as soon after construction as possible.

In order to keep your building in tip top shape and maintain the 10 year anti rot guarantee, it will need re-treating at least annually. Only high quality timber preservatives should be used and applied in accordance with the manufacturer's instructions. This must be done at least annually to preserve the 10 year anti rot guarantee. For more information please refer to the Waltons T&C's.

1 Year Manufacturer's Guarantee

Subject to the conditions set out in the T&C's (Section 8) the Seller warrants that the Goods will correspond with their specification at the time of delivery and will be free from defects in material and workmanship for a period of 12 months.

Unlike many companies, we publish all of our reviews - good or bad - to give you, the customer, total transparency and peace of mind.

product was not as good as in pictureGood afternoon,

Although I am sorry your product was not as expected, I am pleased we were able to rectify any issues for you quickly.

Kind regards,

As above. I would have been happier if the wood preservative had been applied to the shed parts before purchase. I'm sure that would be popular with some more elderly or disabled buyers.Good morning,

I am glad that you are happy with the quality of your greenhouse. There is a water based treatment on the items already but this only lasts for about 3 months and will therefore require re-treating. Thank you again for your feedback - it is much appreciated.

Love my new lean-to greenhouse. Looks fantastic and my plants are very happy inside. We were missing a set on hinges from the original delivery, but managed to set it up with another set purchased locally, and Waltons shipped the missing parts as soon as I notified them of the problem. Would...Good afternoon,

Please accept my apologies for the issue with the missing hinges but I am glad we were able to resolve this quickly for you. It is great to know that you are happy with your greenhouse and that you would definitely buy from us again. Thank you again for your great...

The 8' x 4' Pent Greenhouse Unit is both stylish and practical. It has been specifically designed to be constructed against the side of a permanent building to maximise your garden area. This unit can be attached to the 8' x 4' Pent Unit to create a Combi building great for both cultivation and storage.

The greenhouse is constructed by 12mm Shiplap cladding and supported by a 2" x 1" timber framing to create a strong and robust build. In order to allow you to lower the temperature inside your greenhouse, there is an opening window with a secured arm to position at your convenience. The styrene glazing used is a shatter resistant alternative to glass, being light yet sturdy. It is easy to handle and it won’t compromise the safety within your garden if you have young children or pets.

Please Note: The installation service on this product is for assembly only and does not include fitting to the adjoining building.
