Base material: wood
Our experts say this has 5 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 choice of roof covering (mineral felt), is also what we find that 88% of the top 10% of playhouses use.
2. The styrene window installation is known to be a great choice, and our data shows us that 94% of the top 10% of playhouses make use of this kind of glazing.
3. The interlocking log cladding used on this playhouse is one the best available for playhouses rated by our experts.
4. The tongue & groove construction like the one used on the roof of this playhouse is rated one of the best by our panel of experts.
5. Our experts say this the tongue & groove floor material used here is one of the best available on all playhouses.
Below is a brief overview of how some of the key points of this playhouse fairs across the market.
Cladding
The interlocking log cladding(walls) used here is the best form of construction for playhouse walls out of the 3 types [2] we’ve identified on same-size playhouses, that you’ll also see getting used on 1% (1 of 175) of all playhouses analysed [3], and sadly not present at all on any of the 17 playhouses that make up the top 10% of playhouses [4]. In fact this is the only 10′ x 8′ playhouse you’ll find that uses an interlocking log wall [5].

Roofing
Tongue & groove is the cladding used for the roofing, our experts rate this the best form of roof material and is the only type we’ve found on same-size playhouses [6]. This roofing material is used on 26% of all playhouses analysed, and 12% of the top 10% of playhouses. While you’ll find that the Expert Score of this playhouse is 1 point lower than the average for 10′ x 8’s that use tongue & groove roof material (65 vs the average of 66), you can be sure it’s not due to the roofing as this one of the highest scoring materials found on 10′ x 8′ playhouses. 57% of 10′ x 8′ playhouses (4 in total) use tongue & groove construction for the roof.
A 11mm thick roof boarding was used on this playhouse which is an about average thickness used for a roofing material out of 3 thicknesses identified on same-size playhouses [7]. It’s used on 5% of all playhouses with a further analysis of the top 10% of playhouses (17 in total) showing us that none of them use a roof of this thickness. Our data on all 10′ x 8′ playhouses shows us this is the only one to use a 11mm roofing solution.
Mineral felt is used as the roof covering. Our experts say it’s one of the best roof covering materials, and is also the only kind identified on same-size playhouses [8]. It comes fitted on 64% of playhouses and used on 88% of the top 10% of 10′ x 8′ playhouses. Even though the Expert Score of this particular playhouse is below the average 10′ x 8’s cover their roofs with mineral felt (65 vs the average of 68), with it being on 88% of the top 10%, this should give you confidence in its quality. 57% of 10′ x 8′ playhouses (4 in total) make use of a mineral felt material as a roof covering.

Flooring
The manufactures of this playhouse chose tongue & groove for the floor construction, we rate this the best form of floor construction out of 2 types found on same-size playhouses [9]. This type of floor construction is used on 41% of all playhouses we analysed, and 24% of the top 10% of those playhouses. 71% of 10′ x 8′ playhouses (5 in total) use tongue & groove construction for the floor. Additionally when taking the average Expert Score of those 10′ x 8′ playhouses (64), the BillyOh Annex Log Cabin Wooden Playhouse is just above the average with an Expert Score of 65.
A 11mm thick floor boarding is used here, this is an about average floor board thickness according to our experts out of 3 found on same-size playhouses [10]. It’s found on 3% of all playhouses and used on 12% of the top 10% of playhouses. Out of all 10′ x 8′ playhouses it turns out that this is the only one to use a 11mm flooring.

Window
Styrene windows come installed on this playhouse. As a glazing option, we rate it one of the best out of the 2 glazing types found on 10′ x 8′ playhouses [11]. This particular type of glazing is used on 77% of all windowed playhouses and 100% of the top 10% of playhouses with windows we analysed. Even though the Expert Score of this particular playhouse is 1 point below the average of 66 for windowed 10′ x 8’s use styrene windows, with it being on 100% of the top 10%, you can be assured that this playhouse is using a quality glazing type. 67% of 10′ x 8′ playhouses with windows (4 in total) use styrene windows.
The windows on this playhouse use a 1mm thick glazing, we rate this one of the worst thicknesses for window glazing. You’ll also find this is the only thickness glazing used on same-size playhouses [12]. Glazing this thick is found on 2% of all the windowed playhouses we analysed and our analysis of the top 10% of playhouses shows us that none of those 16 playhouses that make up the top 10% come with a glazing this thick. Out of all windowed 10′ x 8′ playhouses this is the only playhouse to make use of 1mm windows.
The 785mm x 540mm windows on this playhouse are 14% larger than the average 10′ x 8′ playhouse. The window height is 540.00mm (2′) tall which is 4% taller than the average 10′ x 8′ with 21.00mm (0.1′) extra height.

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. ↩
2. Styrene (Polystyrene (High Impact) HIPS): Styrene as it is commonly known or High Impact Polystyrene (HIPS) is a very versatile form of plastic. It has a very wide range of uses but for garden buildings styrene is typically used as a budget option for windows.
Styrene is a shatter-resistant material, which is why it is ideal for situations where safety needs to be considered, such as playhouses. This benefit can be offset by a few other drawbacks, unfortunately styrene has a tendency to yellow over time (the technical term is Photoyellowing and it is caused by prolonged exposure to UV Light), the degradation of its polymers over time also causes it to become more brittle.
Another drawback of styrene is its thermal coefficient of expansion (it is 80 x 10-6), this is higher than most other glazing options. This means that as the material heats up and cools it can contract and expand more than other glazing options. This cycle can lead to a loose fit of windows over time.
According to data from the British Plastics Fedaration the physical properties of Styrene (Polystyrene (High Impact) are that it is not very good when exposed to high heat with a maximum continuous use temperature of between 60 to 80 °C. This is coupled with the fairly low range the Notched Impact Strength data shows of 10.0 – 20.0 Kj/m². ↩
