Base material: wood

Our experts say this has 3 stand out features. A stand out feature is something found on over 70% of the top 10% of products in a particular category or is an exceptionally good feature as rated by our panel of experts.

1. The shiplap tongue & groove cladding used on this shed is one the best available for sheds rated by our experts.

2. A 72mm thick cladding like the one used on walls of this shed is one of the best rated by our experts.

3. A floor that is 16mm thick is something our experts say is one of the best available for this kind of shed.

You Might Also Consider

We found 137 20′ x 10′ sheds with comparable specifications. The 6 x 3m Insulated Garden Room has an Expert Score that is 4% higher than average and is £80 more expensive than average. If you are looking for the best value or highest expert scoring sheds out of the 137 with comparable specifications the following might be of interest.

Best value – If you are looking for something comparable that costs less, then you could save £11,601 with this Optional extra – Add top coat Workspace Shiplap 10′ x 20′ Dip Treated Shed Double Door with Four Opening Window Top Coat. It is priced at £399, this is 2905% less than this and has an Expert Score of 92, 2 points higher than the 6 x 3m Insulated Garden Room.

Highest Expert Score – With an Expert Score of 95 vs 90 for this product, the 14 x 15 WINDOWLESS Reverse Premier Pressure Treated Tongue And Groove Apex Shed With Higher Eaves And Ridge Height Double Doors + SUPER STRENGTH FRAM is the best 20′ x 10′ shed with comparable specifications, and is priced at £7,637, that’s £4,363 less than the 6 x 3m Insulated Garden Room.

High Wind Area – If you live in a particularly exposed or high wind area then having a shed with a thicker cladding and higher than average frame thickness can be preferable. We found at least 3 sheds that have a combination of features that can make them more suited to higher wind areas.

Coastal Consideration – If you live in a particularly wet or harsher environment such as by the coast then you might want to consider something with a more robust pressure treatment or something made from metal or plastic, both materials that are particularly suited to such harsh environments. We’ve found at least 3 sheds that have a combination of features that can make them more suited to higher wind areas.

11′ x 17.2′ Palram Canopia Yukon Dark Grey Plastic Shed

Public-Facing – Extra security measures might be more of a concern if you’re placing your building in an area that is more public-facing than a garden. Features such as security windows or even having no windows at all, and the ability to lock all opening doors are usually much more important when you have something that is more public-facing. We found at least 3 sheds that have options that you might find a better fit if this is a concern you have.

More Child Friendly – If you have children and you are looking for something that has that little extra in terms of durability then tougher glazing options might be a better option. Here we have at least 3 other options that will fill those needs.

1. Untreated: Any wooden structure that is left untreated will have its lifespan dramatically shortened. This is especially the case with Douglas fir or European softwoods such as Whitewood (spruce) or Redwood (Pine), most garden buildings sold in the UK are made from such wood.

The Wood Protection Association says that “the risk of attack increases significantly if the moisture content of wood, for any reason, rises above 20%” they also talk about how more lower durability cuts of wood (known as sapwood) are getting used to build with than in years gone by. They also say that “sapwood on the other hand is a source of food for many species of fungi and insects and is always vulnerable to attack.” This risk is particularly prevalent with European softwoods.

The BS 8417 code of practice (this advises on the choice of timber species and the use and application of wood preservatives) and BS EN 350:2016 (this advises on methods for determining and classifying the durability of wood and wood-based materials against biological wood-destroying agents) says the natural durability class of such European softwoods is between 3 and 5. With class 3 listed as moderately durable, class 4 listed as slightly durable and class 5 listed as not durable. All three classes have a service life of less than 15 years in a frequently wet environment (such as a UK garden). Yet the application of a preservative treatment or modification of lower durability species is designed according to BS8605 part1 (this is the British standards specifications for external timber cladding) to extend service life to 15/30 years or more.

Having a wooden garden structure supplied as untreated is relatively rare. The vast majority of wooden buildings are supplied with some form of basic treatment, usually a short term water based dip treatment. If you buy an untreated wooden building/structure then we strongly advise that you treat it annually with a solvent-based wood treatment. For full penetration it requires 2-3 coats. It is also recommended that you treat the inside of the structure as well.

If you are wanting something that will require much less maintenance throughout the products life cycle then we would strongly suggest looking at something that is pressure treated also known as tanalised timber.

By correctly treating timber you can take a sub 15 year service life for a not very durable European softwood and extend its service life to 15/30 years or more according to the Timber Decking and Cladding Association
