    1.5 x 2.2m Palmako Log Cabin Extension -


    Invest in this handy side storage extension, built exactly the same as your cabin for the same lasting effect. If you choose to not mix storage with lounging space inside the cabin or simply want to add additional space then this is perfect for you. The extension is built from the same Nordic spruce and has the same design which makes it just as strong and resistant as your cabin.

    It sits of the ground the same height causing no issues with alignment thanks to the pressure treated floor joists, also stopping any floor rot from occurring. The gradient–ed roof means weather rolls of the top and will not cause issues at all. A single front door provides access inside the extension and is wide enough to fit tools and bikes relatively easily. Just like the cabins, security is thought off and a cylinder lock is planted inside the door frame to prevent any damage and theft to your items.

    A 5 year guarantee is assured like the cabins and is delivered with an assembly kit which oversees a hassle free installation. So if you need a little extra space or want organisation, this extension is the perfect addition for you and following its sister cabins build design, you will be far from disappointed.

    Quick and simple to install, the ProBASE 18'x18' plastic shed base kit is ideal for avoiding the hassle of laying slabs or concrete when preparing a base for a new shed. Its interlocking design makes it easy to put together and, though lightweight, it provides a very strong and durable base for the shed.

The 18x18 (5.4x5.4m)Palmako Helena 70mm Log Cabin features thick 70mm logs, excellent design features and a high quality build for a premium year round log cabin that can be used as a garden office, family room or a multitude of other uses.

The garden room has 24.6m² of space plus a large roof overhang providing further shelter.

This log cabin is manufactured from interlocking 70mm Nordic spruce logs with a chalet-cut finish. This chalet-cut design facilitates a tighter interlocking build for enhanced protection from wind and rain. One of the greatest log thicknesses, 70mm offers excellent insulation for better year round use. Threaded rods for wind protection further aid the stability while traditional corner notch construction adds charm.

The floor and roof are both constructed from 19mm tongue and groove. Tongue and groove is well-known for its weather resistance, durability and strength. The floor is also supported by pressure treated floor joists to provide a hardwearing and long-lasting structure for many years of use. The roof creates a large overhang, protecting the front of the cabin as well an extra sheltered area for relaxing. The roof is finished with scalloped barges, complementing the traditional design.

Half-glazed with Georgian style windows, the double doors also benefit from a laminated door frame construction. This provides resistance to the warping and cracking associated with changes in temperatures. The door hinges are 3D meaning they are adjustable in the and z axis allowing for exact adjustments of the way the door is hung and thus improving use and insulation. A key-operated cylinder lock provides security while a stainless steel door sill cover protects this high traffic area. Three large tilt and turn opening windows provide light and ventilation to the 18x14 log cabin. Aluminium window gutters prevent water damage. The doors and windows are all double-glazed with real glass and fitted with rubber seals to eliminate draughts and improve insulation.

The garden cabin is supplied untreated with a five year guarantee. We would suggest that an anti-fungal treatment is applied upon assembly and annually thereafter to support the guarantee. Alternatively, paint could be applied for a more individual style.

Please note that the roof does not include a covering. Buy SBS, Charcoal Felt Shingles or Roof Underlay Felt as an optional extra.

(SBS is a thick, torch-on weatherproof felt with a very long lifespan. Installation should only be carried out by those with advanced DIY skills or a professional installer.

Weatherproof Charcoal Felt Roof Shingles are attractive, easy to fit and will last for years.

Roof Underlay Felt is simple to nail on to the garden building but should only be used as a temporary roof covering or as an underlay to a permanent weatherproof roof cover upgrade.)

This Palmako Helena is available as a 18x14 or 18x18 log cabin.
