Our verdict on the Redlands 8′ x 12′ Osprey Summer House

The Redlands 8′ x 12′ Osprey Summer House comes with a hipped style roof, holds a 10 Years guarantee, is fit with lockable double doors that use a lock and key locking system, is treated using a dip treated process [1], and makes use of certified sustainable materials. The 4 georgian windows used on this particular 11′ x 7′ use a 2mm styrene [2] material.

Base material: timber

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

Cladding

Outstanding, our experts say most of the cladding options used are among the best.

The shiplap tongue & groove cladding(walls) used here is one of the best forms of construction for summer house walls out of the 3 types [3] we’ve identified on same-size summer houses, that you’ll also see getting used on 50% (368 of 741) of all summer houses analysed [4], as well as being used on 49% (36 of 74) of the top 10% of summer houses [5]. Even though the Expert Score of this particular summer house is 8 points below that of the average shiplap tongue & groove clad 11′ x 7’s (they have an average Expert Score of 80), with it being on 49% of the top 10%, its use here is a reassuring sign of a high quality cladding. You’ll also find the shiplap tongue & groove cladding showing up on 52% of 11′ x 7′ summer houses (75 in total) [6].

The walls are 12mm thick and we rate this an about average thickness out of the 3 found on same-size summer houses [7]. It is used on 78% of all summer houses [8] and is also used across 92% of the top 10% of summer houses [9] we analysed. Even though the Expert Score of this particular summer house is 12 points below the average 12mm clad 11′ x 7’s score of 84, the fact that 92% of the top 10% use a cladding this thick is reassuring as a sign of quality. 85% of 11′ x 7′ summer houses (121 in total) use 12mm thick walls [10].

Roofing

Tongue & groove is the cladding used for the roofing, our experts rate this the best form of roof material out of the 3 types we’ve found on same-size summer houses [11]. This roofing material is used on 69% of all summer houses analysed, and 81% of the top 10% of summer houses. Even though the Expert Score of this particular summer house is 12 points below the average of 84 for 11′ x 7’s using a tongue & groove roofing, with it being on 81% of the top 10%, you can be assured that this is a quality roof material. 80% of 11′ x 7′ summer houses (114 in total) use tongue & groove construction for the roof.

A 12mm thick roof boarding was used on this summer house which is one of the best thicknesses used for a roofing material out of 4 thicknesses identified on same-size summer houses [12]. It’s used on 66% of all summer houses and 81% of the top 10% of summer houses. Even though the Expert Score of this particular summer house is 12 points below that of the average for 11′ x 7’s that use 12mm roofing (72 vs the average of 84), with it being on 81% of the top 10%, this should give you confidence in its quality. 76% of 11′ x 7′ summer houses (108 in total) use a 12mm thick roof boarding.

Mineral felt is used as the roof covering, and out of 4 types identified on same-size summer houses [13], is said to be one of the best roof covering materials. It comes fitted on 26% of summer houses and used on 43% of the top 10% of 11′ x 7′ summer houses.

If you are looking for the best value or highest expert scoring summer houses out of the 6 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 £1,580 with this Adley 10′ x 6′ Honeybourne Summer House. It is priced at £964, this is 164% less than this and has an Expert Score of 80, 7 points higher than the Redlands 8′ x 12′ Osprey Summer House.

Highest Expert Score – With an Expert Score of 87 vs 72 for this product, the Redlands 10′ x 10′ Contemporary Summer House is the best 11′ x 7′ summer house with comparable specifications, and is priced at £2,119, that’s £425 less than the Redlands 8′ x 12′ Osprey Summer House.

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

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 summer houses 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. Dip Treated: Dip treating is a temporary protective base coat treatment that is mainly designed to help protect the building during transit and for around one month after it is assembled. This water-based treatment is the least time-consuming and cheapest type of wood treatment. It involves dipping the wood in a protective water-based preservative and then leaving it to dry. The action of dipping is where ‘dip treatment’ comes from.

A dip-treated garden building is not considered fully treated with wood preservatives; it’s vital to re-treat your dip-treated building, preferably with a solvent-based (or oil-based) wood treatment. Then re-treat it on an annual basis using a solvent-based (or oil-based) wood treatment.

If you don’t want to treat something on an annual basis then a pressure treated wooden building might be a better option, this is where the wood undergoes a process called tanalisation (pressure treatment) during production. This is where the timber is submerged in specialist wood preservatives (such as Tanalith E, this is actually the origin of the word ‘tanalisation’), the wood then goes into a high pressure vacuum tank 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 Wood Protection Association has a good article/video on this. 

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.
