Cotswold Aesthetic
OUR ETHOS
Our company is committed to sustainability by integrating eco-friendly practices throughout the design, manufacturing, and construction process. We focus on minimising environmental impact, promoting biodiversity, and building durable structures that stand the test of time
FSC Certified Timber: We only use timber products sourced from responsibly managed forests, ensuring that our structures do not contribute to deforestation.
Recycled Materials: Our decking often uses Millboard, a product made with recycled fillers and biopolymers, offering a low carbon footprint.
SIPs Construction: Structural Insulated Panels (SIPs) are used for superior, eco-friendly strength, offering top-notch insulation while using fewer raw materials.


High-Quality Insulation: Our garden rooms are designed for year-round use with BRE Green Guide 'A' Rated insulation, ensuring high thermal efficiency and reduced energy bills.
Efficient Heating & Ventilation: We install low-energy heating systems, LED lighting, and smart, energy-efficient ventilation units to minimize energy wastage.
Glazing: We install double-glazed windows and doors as standard, with options for triple glazing, reducing heat loss.
Water Management: We install full guttering systems and encourage the use of water butts to collect rainwater for garden use.
Minimal Site Disruption: Our teams operate with care to ensure the existing garden landscape is disturbed as little as possible.
Local Suppliers: We prioritize local suppliers to minimize transportation distances and reduce carbon emissions.
​
Our garden rooms are designed to complement the Cotswold aesthetic by blending traditional charm with modern functionality. Using premium materials like Western Red Cedar, they provide a durable, stylish, and comfortable space that complements the natural beauty of the local landscape and traditional cottage aesthetics.
​
How Our Garden Rooms Match the Cotswold Look:
Natural Materials & Finishes: Our rooms often feature premium Western Red Cedar cladding, reflecting the organic, earthy tones found throughout the Cotswolds.
Architectural Flexibility: We can create bespoke designs, including gable roofs that match traditional local architecture rather than a standard shed appearance.
Year-Round Usability: Built with high-spec materials, our insulated and fully finished rooms provide a comfortable, warm space that feels like a natural extension of your home.
Tailored Design: We offer custom options to ensure your garden room fits seamlessly with your existing garden design, whether it's a quiet, natural corner or a more formal setting.
Professional Craftsmanship: With over 15 years of experience, we manage the build from concept to completion, ensuring the highest standards of quality.
​
These features ensure that a new garden room adds both space and value to your property without disrupting the tranquil and historic atmosphere of a Cotswold garden.

- The Jarvis Team
Precision Engineering & Premium Materials
We never compromise on the "bones" of your garden room. From high-grade Western Red Cedar cladding to precision-laid porcelain paving, we source only the finest, sustainably-sourced materials.
Our rooms are fully insulated and climate-controlled, ensuring a professional workspace that remains comfortable 365 days a year.
The Oxfordshire Standard of Craftmanship
Our local team of expert installers and landscapers take pride in the details. Whether it's the seamless grout lines on your patio or the hidden electrical wiring in your office, we treat every garden as if it were our own.
If it isn't perfect, is isn't a Jarvis project.
End-to-End Project Care
A garden transformation should be an exciting experience, not a stressful one. We provide a "turnkey" service, meaning we manage everything from the initial groundworks and drainage to the final coat of paint. You will have a dedicated point of contact throughout the entire build to ensure total transparency.
Our 10-Year Structural Promise
We stand behind the longevity of our work. Every Jarvis Garden Room comes with a 10-year structural warranty, giving you the confidence that your investment is protected for a decade and beyond.
