In-Depth Review of the 20’x18′ Sigma | 44mm Log Cabin
As enthusiasts of outdoor spaces and natural aesthetics, we appreciate the value that a well-constructed log cabin can bring to your garden or property. One option that caught our attention is the 20’x18′ Sigma | 44mm Log Cabin by Tiger Sheds. With its spacious dimensions and quality build, let’s examine what makes this log cabin stand out while also looking at the factors that could give potential buyers pause.
Product Overview
The 20’x18′ Sigma model features interlocking log cladding, a traditional choice that promises durability and aesthetic appeal. While the cabin comes untreated, thus requiring your own weather-proofing, we feel that this provides an excellent opportunity for homeowners to add their personal touch with custom treatments. The double doors provide a grand entrance, reinforced with a reliable 3-lever lock system for security.
Design and Build Quality
The cabin boasts an impressive cladding thickness of 44mm, positioning it among the top 80% of log cabins evaluated. We find this thickness particularly appealing as it offers additional insulation, making the cabin a suitable option for varied seasons. The use of tongue & groove construction is seen across the roof and floor as well, providing superior stability that we really like seeing in outdoor structures.
We were pleased to discover that this model includes four joiner made windows, fitted with 3mm horticultural glass. While the glazing thickness leans towards the average performance, the quality of the windows aligns with the characteristics we’ve come to expect from well-constructed cabins. In fact, the window dimensions (645mm x 1045mm) are both tall and practical, allowing natural light to fill the space, while the total height of the cabin is a comfortable 2189mm.
Ease of Construction
According to expert reviews, we scored the ease of construction at a solid 4 out of 5. While we didn’t find any major obstacles in the assembly process, the untreated timber adds a layer of responsibility for the homeowner. This means you may need additional time to treat the wood before and after assembly, which could offset initial ease for some buyers. However, given the quality materials used in its construction, you are likely to have a rewarding experience crafting your cabin.
Performance and Value
When it comes to performance, we were slightly underwhelmed by the product’s value for money, scoring it at 2.5 out of 5. Priced at approximately £9,198.69, it is arguably on the higher end of the spectrum compared to its counterparts. For those looking strictly at value, you may find alternatives that deliver comparable performance for less. Nevertheless, we should stress that the 20’x18′ Sigma doesn’t compromise on build quality or materials.
For instance, a similar model, the Palmako Helena 5.4m x 5.4m Log Cabin, offers enticing features and is priced lower, making it appealing for buyers who want both quality and budget-friendliness. The Helena model carries an expert score of 87, far exceeding the Sigma’s 72, and is significantly less expensive.
Conclusion
Overall, the 20’x18′ Sigma | 44mm Log Cabin presents an opportunity for those seeking a reliable and aesthetically pleasing outdoor space. Its construction quality stands on solid ground, and its classic design allows for a myriad of personalizations. While we found areas, particularly in value for money, where it may not compete as effectively, for the right buyer, this log cabin could serve as a cherished garden retreat.
Ultimately, your choice will depend on priorities such as budget, intended use, and your aesthetic preferences. If you’re leaning towards durability and craftsmanship and are willing to invest, the Sigma could indeed be a worthy addition to your outdoor landscape.
Product Details
Q: What type of locking system does this garden building feature?
A: This product is equipped with a robust 3 Lever Lock, providing enhanced security. From my experience, a multi-point locking system not only ensures that your belongings are protected but also adds an element of peace of mind, especially if you plan to use the building for storage or as a hobby space.
Q: How is the floor constructed in this garden building?
A: The floor is made from Tongue & Groove boards, with a thickness of 19mm. This method of construction is beneficial because it provides a sturdy base that can withstand daily wear and tear, making it ideal for a garden shed or workshop. The solid structure minimizes movement, and I find it enhances the longevity of the building.
Q: What glazing material is used for the windows?
A: The garden building features horticultural glass, which is 3mm thick. While this type of glazing allows plenty of sunlight in, it is worth noting that it is less durable than other options like toughened or double-glazed glass. If you're in a high-impact area, you might want to consider potential replacements in the future. However, the clarity and natural light it provides are certainly appealing for a garden office or studio.
Q: What roofing material is included with this structure?
A: The roof is covered with mineral felt, known for its water-resistance and durability. This type of covering is a solid choice for protecting the structure from the elements. However, keep in mind that while it is relatively low-maintenance, it may require occasional inspections and possible replacement down the line to avoid leaks in heavy rain.
Q: Can you describe the dimensions and internal space of this garden building?
A: The overall dimensions of this garden building are quite spacious, measuring 4150mm in depth and 3550mm in width, with an internal ridge height of 2507mm. This ample space allows for flexible usage, whether you're using it as a workshop, garden office, or leisure area. The height is particularly advantageous for taller individuals and offers a comfortable space to move around in.
Q: What style of windows does this garden building come with?
A: The windows are joiner made, which typically means they're professionally crafted for quality and aesthetics. They add a charming touch to the overall design. I find that well-made windows enhance not only the appearance but also the insulation of the building, though be sure to check their seals periodically for best efficiency.
Q: How heavy is the packaged unit, and how does that affect installation?
A: The packaged weight of the unit is approximately 1145 kg, which is substantial. While this indicates a sturdy structure, it may complicate the installation process. I recommend having a team or professional help with delivery and assembly to ensure everything is managed safely and effectively, particularly to avoid any potential damage or misalignment during setup.
Q: What is the external size of this building, including the roof?
A: When including the roof, the external dimensions are 4650mm by 3750mm. This larger footprint means you'll need to consider the location in your garden carefully to ensure it fits well within your available space, while also allowing for any required access for maintenance or repairs in the future.
