The Waltons 10ft x 10ft Helios Summerhouse is bright, spacious and superb value for money. The cladding used is made from 12mm shiplap tongue and groove board, which locks together to form a solid panel. This has also been used for the floor as well as the curved roof! The six large windows allow for a brilliant view of your garden and have been glazed using styrene a shatterproof, safe alternative to glass. The large double doors come with a lock and key for security. The unique curved roof design brings a modern touch to the classic summerhouse and will make the Helios an instant focal point in your garden.

Important Information

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.


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.

You can book the day of your choice for delivery when placing your order, alternatively you may place your order without selecting a delivery date and one of our team will contact you directly to arrange a suitable delivery date.

Important - Unless otherwise stated delivery is kerb side only, though at the drivers 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.

Review:Waiting for reinstallation as it is taking way too long....not so happy as it has delayed many things that go inside the summer house
Our Reply:Hi Alsbur, Thanks for your valued feedback. I am chasing up with our install team to get a date for us to re attend. Kind Regards Waltons

Review:Quite thin boards for the price. A few knot holes and boards that weren't uniform shape included, so had to use wood filler for these. Floor is quite "springy". Looks nice though (once painted) and plenty of space inside for table and chairs.
Our Reply:Good afternoon
Thank you for your feedback. I have passed your comments regarding the finish to the manufacturing department.
Kindest regards

Review:Good concept, variable build quality - some of the nailing was dodgy (bent over rather than hammered in), one of the roof panels had to be adapted slightly to fit.

Review:It has not been erected yet but we saw this Summer House at your display area near Newark and it is solid and well constructed - which is why we bought it. If we had had any option we would have liked glass windows.
