Architectural Vision Meets Master Craftsmanship

At Sleek Garden Rooms, we bridge the gap between traditional home extensions and modern architectural design. As specialist garden annex builders, we are more than just installers—we are master craftsmen dedicated to creating bespoke garden rooms that serve as fully functional, self-contained living spaces.

Our mission is to provide high-end, year-round living solutions right in your backyard. Whether you require a luxury granny flat for a loved one, a premium guest suite, or a detached garden office, our buildings are engineered to the highest standards. We use advanced structural insulation and premium materials to ensure every annex is energy-efficient, durable, and indistinguishable in quality from a brick-and-mortar home.

The Studio

Maximum impact, minimum footprint. The perfect garden retreat or luxury home office.

The Suite

The ultimate living solution. Spacious, self-contained luxury for modern families

The Lodge

Nature meets modernism. Bold architecture paired with sleek natural finishes.

Why Choose Sleek Garden Rooms

Architectural Personalisation

Every garden and family need is unique. We offer a bespoke design service that allows you to customise everything from the floor plan and window placement to premium cladding finishes like Western Red Cedar or modern composites.

Thermal Integrity

Our builds aren’t glorified sheds; they are high-performance spaces. We deliver “A-rated” insulation that keeps your room cool in the summer and warm in the winter.

Fixed-Price Certainty

 We provide a comprehensive, fixed-price quotation following your site survey. Once the design is locked in, the price is set. There are no hidden “extras”—what we quote is exactly what you pay.

Turnkey Service

We handle every single trade. From groundworks and plumbing to high-end electrical fit-outs and the final coat of paint, we deliver a “ready-to-move-in” space. You just provide the furniture; we provide the rest.

Seamless Planning

We can guide you through the entire process, including all council correspondence and building regulation applications.

High-Speed Delivery

A traditional home extension can take 6 months and turn your garden into a mud pit. Our precision-engineered annexes are often completed in a matter of weeks, with minimal disruption to your daily life and zero mess left behind.

Your Shortcut to Luxury: Planning Without the Stress

The “Stress-Free” Advantage

For most homeowners, the word “Planning Permission” evokes images of endless paperwork, months of waiting, and the fear of a “No.” At Sleek Garden Rooms, we’ve pioneered a smoother route. By expertly utilizing the Caravan Act, we can often bypass the traditional planning application process, allowing you to bypass the red tape and move straight to the excitement of your build.

Why This Route is Better for You:

  • Faster Approval Times: While a traditional planning application can take 8–12 weeks (or more), our route focuses on obtaining a Lawful Development Certificate (LDC). This is a faster, more definitive confirmation from your council that your project is legally sound.

  • Total Legal Certainty: We don’t leave anything to chance. Our team manages the entire submission to your local authority, ensuring your annex meets the specific legal definitions of the Caravan Act. You receive a certificate that acts as a “legal shield” for your property’s future resale.

  • No Hidden Fees: Traditional planning often involves expensive architectural surveys and application fees. Because we use a proven, standardized legal framework, we provide a fixed-price planning management service with no surprises.

  • A Managed Experience: You won’t ever have to speak to a planning officer or navigate a council website. We act as your professional agents, handling every correspondence and technical query from start to finish.

"We believe your focus should be on choosing your interior finishes, not chasing council officers. We handle the heavy lifting so you can enjoy the journey."
