    18x11 Plastic Shed Base Kit -


    Avoid the hassle or mess of laying slabs or concrete with our 18'x11' ProBASE plastic shed base kit, when preparing a base for your new shed. It is very quick to install as its interlocking design makes it easy to put together and, though lightweight, it will provide a very strong and durable base for your shed.

    Made from 100% recycled plastic, this shed base is eco-friendly. Also, you can reuse the base if you decide to reposition your shed. The base allows for ventilation and drainage under the shed, helping to keep the shed floor dry.

    To install the base, you simply interlock the square grids together and lay onto a firm, level area of ground. We recommend using 15kg of 10m pea gravel per square (gravel not included).

    Each square is 500 x 500 x 40mm. This pack contains 84 squares. For your convenience, a heavy-duty, commercially-graded membrane is also included.

    • Super strong interlocking grid system shed base
    • Simple to lay and assemble
    • Eco-friendly high quality recycled plastic
    • Ventilated design
    • Includes heavy-duty membrane

  • Palmako Rain Gutter for Gable Roof - 700...


    Palmako Rain Gutter for Gable Roof - 7000mm -


    If you have a log cabin with a roof length of up to 7m, then this guttering may be a great option for you to control rainfall. Use this product to direct rain away from your cabin, or use it to collect said rainwater to then use for watering your plants and vegetables. Manufactured using PVC plastic means this guttering is incredibly sturdy and will last a very long time.

    By collecting rain in water butts you are actively making a change to stop wasting as much water as you might do normally to keep your garden looking beautiful. If you start collecting water in the winter, you can still use it throughout the spring and summer! You will be helping reduce your own water bill as well as the environment by recycling rainwater.

With 2 spacious compartments and unbeatable insulation, the 18x11 Palmako Olaf Premium (88mm) Nordic Multi-room Shed (5.6m x 3.3m) offers you the perfect combination of generous outdoor storage and a dedicated garden workshop.

Expertly built from 88mm Nordic spruce, fine-sawn tongue and groove cladding, with added wind braces, this superior garden shed is even more robust, durable and insulated than a premium log cabin. Both the floor and reverse apex roof are constructed from 19mm tongue and groove, the former including treated foundation joists to protect the interior from ground moisture. 

You can gain easy access to the 10m² section of this wooden shed via double doors, while a single door leads to the 6.9m² area. As befits a garden workshop, both sets of doors are positioned on the wider side of the structure. They feature laminated frames and cylinder locks, so rest assured that your valuable tools and equipment will remain secure.

You can enjoy natural light when hard at work inside thanks to a window on the side of the structure. It is made from real glass, fully framed and further enhances the shed’s attractive appearance.

Ready-made wall elements and doors, clear instructions and a complete set of fixings are all supplied to help you achieve a straightforward assembly, even if you’re inexperienced at DIY. All of the parts are covered by a 5 year guarantee.

You can purchase this shed, with the same premium specifications, in a smaller size.

*This workshop shed is supplied untreated. We advise coating it with a quality wood preservative within 6 weeks of assembly, and annually thereafter, in order to prevent rot and maintain the wood’s attractive appearance. If you’d like a more individual look, you can paint this garden shed instead.*

Please be advised that the roof does not include a cover as standard. Select from SBS, Charcoal Felt Shingles or Roof Felt Underlay as an optional upgrade.

(SBS weatherproof roof covering is a thick, torch-on felt with an exceptionally long lifespan and outstanding weatherproof qualities. Unless you possess advanced DIY skills, we recommend hiring a professional installer.

Heavy-duty Charcoal Felt Roof Shingles are a permanent weatherproof roof covering, which is attractive, easy to instal and extremely durable.

Roof Underlay Felt is simple to nail on to the garden building but is only designed as a temporary solution until you have added a permanent weatherproof roof cover upgrade.)

The Delivery Process

Your delivery will be made between 8am and 6pm on your pre arranged delivery date; the delivery team will contact you to book via phone.

Our service is a Kerb side pallet drop delivery by a crane off-load vehicle. Unfortunately we will not be able to unpack your log cabin and take your goods to the back of the property. We typically plan to deliver to the front garden or drive.

Log cabins are delivered in two packages, flat packed, direct to your home and supplied with a comprehensive set of instructions to help you get started.


Extended Lead Times: Due to the impact of the pandemic on manufacturing across the nation and on the importation of raw materials, alongside the highest demand for gardening products the industry has ever seen, some lead times for products are now longer than usual. Manufacturers are working hard to keep supplying customers. Thank you for your patience.
