Do you have a need for a small, budget-friendly shed taking up very little space? Then look no further! This could be the ideal solution for customers wanting to tidy up their gardens by stowing away lawnmowers, those often used garden tools, brooms and the like. Made from durable overlap cladding attached to a 28mm x 28mm frame, the storage unit also comes complete with a sand-felt coated OSB roof and hard-wearing sheet floor. Being a windowless design means that whatever you keep inside will be out of sight and by adding your own padlock to the supplied hasp and staple, safely secure too! Compact in stature but big in charm, this rustic looking garden store will integrate well into most garden settings. 


About the Timber and Cladding

Being constructed utilising rough sawn overlap timber, the shed has that instant rugged appeal and its rustic look is an attractive feature. Overlap cladding while not only being sturdy and simple to manufacture offers great water-resistance through its louvred orientation. The boards being angled and lapped sufficiently to aid water run-off, also offer great ventilation properties helping minimise condensation.

FSC certified timber is used throughout the body of the building and with the peace of mind of our 10-year anti-rot warranty, you can be assured that by following a basic care regimen your shed should look good for years to come.

Having a single door keeps the design uncomplicated and with its durable, braced assembly and galvanised metal hinges it is kept in place with a simple turn button. Although the shed doesn’t come with a lock, provision is made for this using a sturdy hasp and staple which is included in the kit.

Roof and Floor

OSB (Oriented Strand Board) is a tried and trusted material used widely in the manufacturing industry. It’s a solid and highly water-resistant material with similar properties to plywood. Coupled with a protective layer of sand-felt, your shed roof will remain water resistant and weather-proof well into the future. Similarly, the same material is utilised in the floor and with the attached bearers high load-bearing properties are achieved and problems with damp and mould are kept to a minimum.

The Kit

Even though a convenient service to erect the shed can be purchased, don’t be surprised to find how easy this shed is to install yourself. With a little help, some basic tools and a spare few hours you could soon have the satisfaction of building this fabulous budget-friendly building which could be an attractive and practical feature for your garden.

Please note:

All our sheds are pre-treated with a water based timber treatment for protection during transit. In order to receive the full 10-year anti-rot guarantee on your shed, it is necessary that you treat the shed with high quality, water-based, timber preservative prior to or shortly after construction. This will protect the timber from weathering on your shed and will need to be repeated accordingly in relation to the manufacturer's instructions. This guarantee does not cover twisting, warping or splitting of the timber over time.

Elbec recommends Protek Royal Exterior wood finish, available from ourselves in many different colours. This is also a great way to refresh the look of your shed over time or personalise it to your liking.

Delivery Leadtimes

The estimated delivery lead time for this product is identified on the product page above. Lead times are in working days (Monday - Friday) excludes Bank Holidays. These estimated lead times are provided by the manufacturers and are not guaranteed - due to fluctuation in demand - but are provided in good faith and are representative of delivery at that time. Some remote areas will take a little longer.

Upon Delivery

Your order is delivered either kerbside or driveway and will be delivered on a 17 ton lorry (the size of a Refuse Cart). Unfortunately due to health and safety and insurance liabilities the driver will not be able to take your goods around to the back of your property but may upon request place the product at the side of the house if there are no access or restriction issues. We would not risk damaging your property whilst delivering a product to an un-safe location. Unfortunately we will not be able to go through your property.

You do not need to be home for your delivery. All we ask is that you let us know via email or leave a signed note to let us know that you will not be present for the delivery. In the note please let us know where a suitable place would be to leave the building. If you leave us a note the delivery driver will ring you 30 minutes before delivery and you can inform them of where the note is or you could just leave it on your front door. You must include your signature on the note; our drivers can then take photos of the note to confirm an item(s) has been delivered.

We would recommend against arranging for a third party to install the building before it's been delivered and checked that all parts are present, as we cannot be held liable for any third party costs.

Installation Option

If you have chosen our installation option your order will be delivered as per the delivery process above you have chosen. You’ll be given a separate date for the installation. The installation option will extend your lead time by up to 10 working days.
