Embrace the futuristic Forest Xtend 3.0 Insulated Garden Office, a contemporary garden sanctuary crafted to harmonize with your fast-paced routine. Apart from serving as an ideal personal workspace, this versatile garden structure also functions as a year-round family retreat or creative studio.

Innovative Building Design
As a cost-effective substitute for a conventional house expansion, this high-quality garden room is assembled using pre-cut, modular structural insulated panels (SIPs). Many contemporary residences are adopting this cutting-edge approach as SIPs deliver exceptional insulation, energy efficiency, and durability. Unlike other competing brands that focus solely on insulated walls, the Xtend series incorporates SIP construction for both the roof and floor, resulting in an all-around insulated garden compartment.

The superior insulation not only safeguards the home office against moisture but also ensures a cool atmosphere in summer and warmth in winter, creating a comfortable workspace for remote working throughout every season.

Each wall SIP comprises 97mm insulation nestled between two layers of OSB (oriented strand board). The SIPs are enhanced and further insulated by external and internal cladding. The internal cladding showcases MDF with an elegant vertical beaded design for a refined finish. It comes primed and ready for customization through painting. The external cladding comprises top-notch, kiln-dried 15mm tongue and groove timber, providing not only a stylish appearance but also a weather-resistant structure. The combination of SIP, cladding, and cavities confers a substantial overall wall thickness of 177mm.

Floor and Roof
To elevate the insulation level, the 108mm floor and 122mm pent-style roof are also constructed using SIPs. The floor is left uncovered, allowing for diverse finishing options such as carpet, laminate, or other preferred flooring materials. The interior of the roof is adorned with pre-primed interior cladding, awaiting your personal touch with paint. On the exterior, the roof presents a cutting-edge, black EPDM weatherproof roof covering with an impressive 50-year lifespan. This rubber roofing material resists splitting or cracking, deters moss and algae growth, is UV-stable, and demands zero maintenance. A modern touch is added with anthracite grey fascias to complete the contemporary look.

Forest does not provide electrical services. However, the 28mm wall battens and 45mm roof battens are meticulously designed to accommodate electrical wiring and recess lights, respectively. It is crucial to engage a certified electrician for any electrical work.

Door and Windows
Access to this garden office is via a double-glazed, UPVC door secured by a 7-point multi-lock system to ensure the safety of valuable equipment. Three additional full-length, double-glazed windows flood the interior with natural light. The top section of the side window can be opened for ventilation. All doors and windows feature grain-effect grey exteriors and smooth white interiors, culminating in an exceptionally appealing aesthetic.

Options and Assembly
This premium insulated garden room is offered in three sizes and with three distinct door/window configurations. All necessary fixtures, fittings, exterior facias, and a step-by-step installation manual are provided for effortless assembly. Forest also offers a professional installation service executed by skilled installers.

Energy Efficiency and Maintenance Guidelines
This garden office boasts an energy efficiency rating of 78 (category C), with the potential to reach 82 (category B) by incorporating a photovoltaic solar panel. Upon delivery, the outdoor office is untreated and should be treated upon assembly and annually thereafter. Forest Garden advises treating it with recommended products such as Sikkens Cetol HLS Plus, Restol Wood Oil, Timmersol ETS Double Protectant, Osmo Country Colour, or Osmo Natural Oil Wood Stain. The internal cladding comes primed and can be painted in any desired color using standard interior emulsion paint.

FAQs

The size of the shed depends on what you plan to store or use it for. Measure the items you plan to store and consider any additional space for moving around or future storage needs. Common sizes range from small (6×8 feet) for basic storage to large (12×24 feet) for workshops or extensive storage.
Sheds are typically made from wood, metal, or plastic. Wood is aesthetically pleasing and customizable but requires more maintenance. Metal sheds are durable and secure but can be prone to rust. Plastic sheds are low-maintenance and easy to assemble but may not be as sturdy as wood or metal.

Permit requirements vary by location. Check with your local building department or zoning office. Typically, small sheds (under 120 square feet) may not require a permit, but larger ones or those with electrical installations often do.

A solid foundation is crucial for stability and longevity. Options include concrete slabs, gravel bases, or wooden platforms. Choose a foundation based on your shed’s size, material, and the ground conditions of your site.
Look for sheds with features like weather-resistant materials, proper sealing, and robust construction. Ensure the shed has a good roof overhang, proper drainage, and secure locking mechanisms to protect against theft and weather damage.
Assembly time depends on the size and complexity of the shed. Small, simple sheds can be assembled in a few hours, while larger or more complex sheds may take a full day or more. Professional installation is also an option for those who prefer not to DIY.
Maintenance depends on the material. Wooden sheds need periodic painting or staining and checking for rot or pests. Metal sheds may need rust prevention treatments. Plastic sheds require minimal maintenance, typically just cleaning as needed.
Moving a shed is possible but can be challenging, especially for larger structures. It’s easier to move a smaller shed if it has a solid base. Consider the logistics and potential costs of moving before installation. If moving is likely, a portable shed might be a better option.
Many sheds come with detailed assembly instructions, making them suitable for DIY installation, especially smaller models. However, larger or more complex sheds may require professional installation to ensure they are properly and safely assembled. Assess your skill level, available tools, and the complexity of the shed before deciding.
