More Than Just a Summerhouse. A True Extension of Your Home

We do not build standard, off-the-shelf cedar sheds. Our luxury timber garden rooms are bespoke architectural commissions. Engineered from the ground up, they feature robust foundations, house-grade insulation, and structural Sapele frames designed to provide a lifetime of unparalleled comfort and style.

Testimonials

What Our Clients Say

Garden Office Client

I needed a professional space to run my business from home. The quality of the Sapele joinery is outstanding, and the room stays perfectly warm even on freezing January mornings.

Home Gym Client

We wanted a high-end studio that didn't look like a glorified shed. The Teknos finish and Sarnafil roof gave us total confidence. The installation was seamless and the end result is stunning.

Studio Client

The team brought the same level of architectural expertise to our garden room as they would a full house extension. It is a beautiful, flawless addition to our property.

FAQ's

Frequently Asked Questions

Unlike mass-produced modular pods or softwood "log cabins," every Farrow & Jones structure is a bespoke architectural extension of your home. We exclusively use Sapele Mahogany, a high-density hardwood that offers superior structural integrity and a furniture-grade finish. Our rooms are built using traditional joinery techniques paired with modern thermal technology, ensuring a permanent building that adds genuine capital value to your property.

Absolutely. We design our garden rooms to the same thermal standards as a primary residence. By utilizing Solar Control Glazing—which reflects 78% of solar heat—and high-performance insulation, we ensure your space remains cool and airy in the height of summer and perfectly temperate during the winter. This makes it a functional sanctuary 365 days a year, whether used as a professional studio or a luxury kitchen.

We offer a comprehensive "Concierge" service to handle the bureaucracy for you. While many garden rooms fall under "Permitted Development," bespoke structures or those in Conservation Areas often require formal approval. Our team manages the entire process—from initial architectural drawings to submitting the application—ensuring your project is fully compliant with local authorities without the stress of managing it yourself.

While Oak is traditional, it is prone to "tannin staining" and movement (warping or twisting) over time. Cedar is soft and easily damaged. Sapele Mahogany is our timber of choice because of its incredible stability and density. It does not move once installed, meaning your doors and windows will never stick, and its tight grain provides a 50+ year lifespan with a finish that remains flawless for decades.

Your peace of mind is built-in. Every window and door aperture is fitted with high-grade, multipoint stainless steel locking systems. Our builds are fully compliant with PAS 24 security standards, providing a formidable barrier against intrusion while maintaining the elegant, slim-profile aesthetic of our bespoke timber joinery.

We believe in engineering for longevity. Our Sarnafil roof systems carry a world-leading full guarantee against leaks, while our Sapele timber frames are engineered for a 50+ year lifespan. When combined with our Teknos Heritage Shield finish, your investment is protected by the highest specifications available in the UK luxury market.

Every project begins with a blank canvas. Because we manufacture everything in our own UK workshop, we can match the architectural details, roof pitch, and color palette of your existing home. Whether you require a contemporary glass-heavy retreat or a traditional timber structure that feels like it has always been part of your estate, our design team ensures a seamless aesthetic transition.
