The 12ft x 8ft Waltons Shiplap Pressure Treated Apex Wooden Shed offers a large interior space that is perfect if you want to build a workshop in your garden. To ensure a durable build that will provide many years of service, the timber has been pressure treated. Pressure treating timber is the process of vacuuming high quality preservative into the fibres of the timber, this offers the best protection against the elements. Featuring 12mm interlocking tongue and groove cladding, the walls of this garden building provide an attractive finish that is resistant against water ingress. In order to ensure the floor and roof can withstand many years of daily use, they have been created from a solid sheet material. A thick 2” x 1” wooden frame forms a sturdy support for the walls, floor and roof.

The double doors make storing large items such as a gardening equipment more convenient because of the wider entrance. Horizontal braced ledging has been added to the inside of the doors for extra support. A reverse apex roof offers additional water drainage, ideal if you want to harvest the rain water, simply add guttering to the edge of the roof and direct the piping into a water butt. High quality mineral felt is supplied to protect the roof from weather damage. Multiple windows allow natural light to flood into the interior; this provides a well ventilated working space. Shatterproof styrene glazed windows are a safer alternative to traditional glass, ideal if you have a young family.

Important Information

Our pressure treated buildings come with a 15 year anti rot guarantee* and offer a high level of protection against weather damage, rot, decay and insect attack. For maximum protection, once installed we do advise applying a waterproofing treatment to your garden building to prevent water ingress. All our buildings also include a 1 year manufacturer's guarantee* as standard.

Pressure Treated Buildings

Modern pressure treating techniques are environmentally friendly, using water-based treatments. However gloves should be worn when handling the parts/assembling the garden building.

Pressure treatment is different to externally applied preservatives and top coat treatments. Chemicals are impregnated into the fibres of the wood under pressure. This is done prior to assembling the building at the factory. By fixing chemicals into the wood, pressure treating offers protection against insect attack, chemical attack and natural decay. This treatment gives the wood a green colour. The building should also be treated with a waterproofing topcoat. While the effectiveness of the treatment does not alter without a top coat, the colour does change over time, and that nice green shade will soon turn grey.

  • 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.
  • 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.

15 Year Anti-Rot Guarantee

Our Pressure Treated Garden Buildings come with a 15 year anti rot guarantee. Pressure treating is a chemical process which helps to protect wood against rot and insect damage. There are many different treatment solutions, the most common chemicals used to pressure treat wood are Alkaline Copper Quaternary (ACQ), Copper Azole (CA), and Micronized Copper Quaternary (MCQ).

Safety: Always wear gloves, eye protection and a dust mask when handling wood. Due to chemicals in pressure treated wood, never burn its sawdust or scraps; instead dispose in a landfill.

In order to keep your building looking great, it will need re-treating at least annually. Always use a high quality waterproofing topcoat, applied in accordance with the the manufacturer's instructions. If left untreated the colour will fade from green to silvery grey in approximately 6 months. 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.
