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 mineral felt roof covering found on this shed is rated to be one of the best by our experts.

2. A floor that is 14mm thick is something our experts say is one of the best available for this kind of shed.

3. A pressure treated treatment like the one used on this shed is one our experts are happy to say is one of the best around.

Below is a brief overview of how some of the key points of this shed fairs across the market.

Cladding

The overlap board cladding(walls) used here is the worst form of construction for shed walls out of the 4 types [4] we’ve identified on same-size sheds, that you’ll also see getting used on 8% (357 of 4,360) of all sheds analysed [5], as well as being used on 3% (12 of 436) of the top 10% of sheds [6]. You’ll also find the overlap board cladding showing up on 19% of 6′ x 4′ sheds (69 in total) [7].

The walls are 7mm thick and we rate this one of the worst thicknesses out of the 12 found on same-size sheds [8]. It is used on 3% of all sheds [9] and is also used across 1% of the top 10% of sheds [10] we analysed. 8% of 6′ x 4′ sheds (28 in total) use 7mm thick walls [11].

While you’ll find that the Expert Score of this shed is 11 points lower than the average for 6′ x 4’s that use osb roof material (80 vs the average of 91), you can be sure it’s not due to the roofing as this one of the highest scoring materials found on 6′ x 4′ sheds. 19% of 6′ x 4′ sheds (70 in total) use osb construction for the roof.

It comes fitted on 22% of sheds and used on 49% of the top 10% of 6′ x 4′ sheds. Even though the Expert Score of this particular shed is below the average 6′ x 4’s cover their roofs with mineral felt (80 vs the average of 89), with it being on 49% of the top 10%, this should give you confidence in its quality. 26% of 6′ x 4′ sheds (96 in total) make use of a mineral felt material as a roof covering.

You Might Also Consider

We found 270 6′ x 4′ sheds with comparable specifications.

If you are looking for the best value or highest expert scoring sheds out of the 270 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 £248 with this Optional extra – Add top coat Shetland Shiplap Apex 6′ x 4′ Dip Treated Shed Single Door with Window Top Coat. It is priced at £112, this is 221% less than this and has an Expert Score of 92, 12 points higher than the 6′ x 4′ Forest Overlap Pressure Treated Reverse Apex Wooden Shed.

Highest Expert Score – With an Expert Score of 100 vs 80 for this product, the Oren 6′ x 5′ Shiplap Pent Bike Shed is the best 6′ x 4′ shed with comparable specifications, and is priced at £619, that’s £259 more than the 6′ x 4′ Forest Overlap Pressure Treated Reverse Apex Wooden Shed.

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.

Oren 8′ x 4′ Shiplap Pent Bike Shed
Redlands 5′ x 6′ Shiplap Modular Apex Bike Shed

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.

6′ x 4′ Forest Tongue and Groove Pressure Treated Wooden 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. Pressure Treated: Considered the most durable wood treatment, this is where the wood undergoes a process called tanalisation. This is where the timber is submerged in specialist wood preservatives (such as Tanalith E, this is actually the origin of the word ‘tanalisation’), this is a unique combination of copper and organic biocide ingredients (it is the copper that gives the finished wood the slightly green colour). The wood then goes into a high pressure vacuum tank (the Wood Protection Association has a good article/video on this) to draw out excess moisture and air and force in the preservatives.

This deep penetration of the exterior wood protects it from the elements and all forms of insect attack. Wood treated this way can last many years without being re-treated. The BS 8417 code of practice (this advises on the choice of timber species and the use and application of wood preservatives) says “ penetration to either 6 mm (15 years) or 12mm (for 30 years) has to be achieved in any exposed surface in sawn material.”

It is also worth noting that if cross cutting, notching or boring treated timber during or after installation, ALWAYS apply an end grain solvent-based (or oil-based) wood preservative treatment to the freshly exposed areas, this will maintain the integrity of the protection. NEVER put cut ends in the ground, even if end grain coated. 

2. Polyethylene: Polyethylene (Low Density) LDPE, LLDPE is not commonly used for the construction of garden buildings or storage units. The most common use for LDPE is in the thin film used to cover poly tunnels.

According to data from the British Plastics Fedaration the physical properties of Polyethylene (Low Density) are that it is not very good when exposed to high heat with a maximum continuous use temperature of 65 °C. This is however offset by the outstanding Notched Impact Strength data that showed ‘no break’. 

3. FSC Certified Timber: The Forest Stewardship Council (FSC) is an international organisation that is “dedicated to promoting responsible management of the world’s forests.” When you see the FSC certification it means the forest where this wood was sourced from is being managed in a way that preserves biological diversity, while ensuring it sustains economic viability. FSC-certified forests are managed to strict environmental, social and economic standards. FSC certified timber is comparable to Certified Timber
