With the addition of the side shed, this summerhouse ticks all of the boxes! This wooden summerhouse is designed to maximise your space by sitting comfortably in the corner of your garden, while giving you fantastic panoramic views.

We manufacture this wooden summerhouse here in the UK, using FSC® certified timber - so you can be confident in the quality of your new garden building. The walls are constructed using 12mm Shiplap tongue and groove cladding to form strong, hardwearing and weather resistant panels. Heavy-duty tongue and groove boards are used to construct the roof and floor, for a strong and heavy-duty finish. The roof is covered with high grade mineral felt for added weatherproof protection. Complete with thick wooden framing to support the cladding internally, this building offers a rigid and long-lasting structure.
Robust fixtures and fittings are all supplied as standard, alongside our detailed instructions and manufacturer’s recommendations, to ensure a simple and stress free assembly. This building comes with a 10 year anti-rot guarantee, alongside a 12 month manufacturer’s warranty. Preservative and waterproof treatment is required to maintain your building and the anti rot guarantee. You must construct this garden building on a firm and level base.

Important Information
Our dip treated summerhouses, 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 summerhouse also includes a 1 year manufacturers guarantee* as standard.
Dip Treated Summerhouses
Our summerhouses are supplied flat packed as DIY kits with full instructions.
It is the customer's responsibility to follow the product instructions and the information outlined within the Manufacturers recommendations.
All of our summerhouses are delivered unpainted. The summerhouses 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 the title in order to make it easier for customers to find, so please be sure to check the item's specific measurements carefully.
Delivery times highlighted with an asterisk (*) refer to working days.
10 Year Anti-Rot Guarantee
Our dip treated summerhouses 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 colourant for protection whilst in storage and transit. This treatment is not a preservative therefore the product will require a preservative and waterproofing top coat application as soon after construction as possible.
In order to keep your summerhouse 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 recommendations. 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.
Planning Permission
Whilst we work hard to design all of our garden buildings to adhere to planning permission guidelines, we cannot guarantee that planning permission will not be required. Therefore we advise that it is always best to check with your local authorities before erecting a garden building.
Aftercare
We want you to enjoy the use of your new summerhouse for many years. To ensure this, it is important your summerhouse is protected 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.
BASE
All long-lasting summerhouses 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 summerhouse 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.
Glazing
Our styrene windows are protected using a clear film which will need to be removed after you've installed and treated the summerhouse. This can be removed easily by scoring round the edge of the window and peeling back the plastic covering.
All Waltons summerhouse 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 summerhouse, 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 summerhouse, 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 CladdingMaterials
Scroll through to learn more about the different cladding styles that are available for our summerhouses.
OverlapCladding
Our overlap cladding is manufactured using thick panels that are nailed to vertical, internal framing with an overlapping profile. Overlap cladding is the easiest and cheapest construction method, making it a cost effective option. This type of construction is great for those looking for a secure, dry storage solution but we would encourage those looking to spend a lot of time inside the summerhouse to consider a Shiplap alternative.
Tongue &Groove Cladding
Although Tongue & Groove boards are generally used for the roof or floor, we do occasionally use this as cladding. This cladding is manufactured using 12mm tongue and groove boards that lock together and are then nailed to the vertical internalframing. This type of cladding is robust, strong and resistant to water ingress and draughts.
ShiplapCladding
We manufacture our shiplap cladding using thick, 12mm tongue and groove boards that lock together and are then nailed to vertical internal framing. Featuring a protective lip, this cladding protects your building from the weather with a tight seal. This type of construction is great for those looking to spend lots of time within the summerhouse or for a more robust and strong storage solution.
Dip Treatment
Our summerhouses are dip treated during manufacture as standard. This is the process in which we apply a water based colourant for protection whilst in storage and transit. This is not a preservative therefore the building will require a preservative and waterproofing top coat application as soon after construction as possible. This is required to validate your 10 year anti-rot guarantee.
Timber is cut ready for treatment.
Timber is dipped into a cylider containing preservative.
Preservative is absorbed into the surface of the timber.
Timber is removed from cylinder containing preservative.
Timber is left to airdry.
Our Roof &Floor Materials
Scroll through to learn more about the different roof and floor materials that are available for our summerhouses.
Solid SheetBoard
Solid sheet board is an engineered wood formed by adding adhesive and then compressing layers of oriented strands of wood to form a strong and robust panel. This material is perfect for everyday use and will form a strong base or ceiling to your building. If you require a more heavy duty flooring for holding large tools and equipment, you may want to consider upgrading to tongue and groove.
12mm Tongue &Groove Boards
Toungue & Groove boards make the perfect roof and floor for frequently used buildings as well as those that will be storing heavier items such as work benches, tools or furniture. The boards interlock to form a tight seal, helping them spread the load within the building. We'd always recommend upgrading to tongue and groove boards if you plan to spend a lot of time within the building or if you're storing heavier items.
Styrene
Styrene is a lightweight product that offers a safe and shatterproof alternative to traditional glass glazing. Used as standard within our summerhouse, summerhouse, playhouse and greenhouse ranges, styrene is ideal for those with busy gardens or young children.
Our RoofCovering Options
Scroll through to learn more about the different roof covering options for our summerhouses.
MineralFelt
High quality mineral felt is supplied as standard across our range of summerhouses, summerhouses, playhouses and log cabins. Mineral felt is a bitumen and fine mineral granule material that provides a weatherproof barrier between the elements & your building.
Superior DutyFelt
Superior duty felt is designed to protect your building against whatever the weather can throw. Our heavyweight felt is 50% thicker than standard felt, with a glass fibre and bitumen base. Ideal for buildings in an exposed area it provides a tough, durable and weatherproof membrane.
Natural Wood Characteristicts
As wood is a natural material it may be affected by the following:
Shrinkage & Warping
The timber used in the construction of your garden building will have retained some of its natural moisture content. The moisture content of the timber will vary, depending upon prevailing environmental conditions, which will result in the components either naturally expanding or contracting. As the components dry out shrinkage may occur. A good waterproofing treatment from the start is the best protection to minimise the effect of moisture loss/intake.
Damp & Mould
During the winter months, cold and damp conditions can result in an increased amount of moisture within your garden building, especially when used infrequently. Condensation can form on the timber and other items stored within your garden building. If left this moisture is likely to cause mould and mildew. To prevent the build-up of moisture, we recommend leaving the door or windows of your building open from time to time, to allow the fresh air to circulate. We also advise against storing wet or damp items in your garden building as this will also increase the level of moisture in the building. If mould or mildew does start to form within your building we recommend using an anti-mould cleaner to remove it and to prevent it spreading, which if left untreated could permanantly damage your garden building.
Splits, Cracks & Knots
Small splits and cracks in some components or holes may appear where knots shrink and fall out. This will not affect the structure of your garden building however if you wish to fill them this can be easily done using any good quality wood filler
Sap
Sap is naturally occurring in wood and may appear in some boards of your garden building. If you wish to remove the sap, we advise waiting until it is dry and then using a sharp knife to carefully remove it. If the removal of the sap causes a hole in the timber, we recommend using a good quality wood filler to fill it.
Please be aware that these are natural timber characteristics which in most cases will not impact the structure or function of the garden building, therefore are not considered as product defects (as outlined within our Terms & Conditions). If you require further advise or information please contact our friendly Customer Services Team.
