Two Visions, One Standard of Excellence

The Contemporary Aluminum Series: Designed for the modern purist. These lanterns feature ultra-slim, aerospace-grade aluminum rafters, providing the maximum possible glass area and a sleek, industrial-chic finish.

The Heritage Hybrid Series: Experience the best of both worlds. Internally, enjoy the natural beauty of Hardwood Rafters featuring delicate Lamb’s Tongue detailing—a nod to 19th-century craftsmanship. Externally, these are protected by our high-performance Aluminum Capping System, ensuring the wood is never exposed to the elements.

The Sapele Advantage

Sarnafil Roof Covering

The Berkshire Value Assurance

We will look to beat any genuine, written "like-for-like" quote from a competitor using the same premium Sapele and Sarnafil specifications.

The Heritage Shield

Teknos finishes are engineered to breathe with the timber, offering unrivaled protection against the elements while resisting cracking, peeling, and fading.

The Fortified Standard

Testimonials

What Our Clients Say

Mr. & Mrs. T, Ascot

The team matched our original brickwork perfectly and the new Sapele roof lantern has completely transformed our kitchen. Truly professional.

J. Edwards, Sunningdale

We were worried about heat, but the solar glass is incredible. Even in July, our new orangery is the coolest room in the house. A fantastic investment.

D. Harrison, Windsor

The 10-week build was clean, the joinery is furniture-grade, and the final plastered finish is flawless. Highly recommended.

FAQ's

Frequently Asked Questions

uPVC is a mass-produced plastic that lacks structural soul. By using Hardwood rafters, we provide a rigid, high-end furniture finish inside your home with exquisite Lamb's Tongue edge detailing. The external Aluminum Capping then acts as an indestructible shield, meaning you get the beauty of wood indoors without the maintenance headaches of exterior timber or the "cheap" look of plastic.

Standard uPVC lanterns feature bulky, rounded plastic corners that look functional rather than beautiful. Our Lamb’s Tongue detailing is a delicate, traditional molding carved into the hardwood. It creates soft shadows and a refined architectural silhouette that uPVC simply cannot replicate.

Significantly. uPVC expands and contracts heavily in the sun, which often leads to seal failure and leaks. Our External Aluminum Cappings are thermally stable and powder-coated to resist the harshest UK and Irish winters. They protect the core structure from UV and rain, ensuring your lantern remains watertight and beautiful for decades longer than any plastic alternative.

Yes. Unlike the limited color "foils" used in uPVC, our aluminum caps can be powder-coated in any RAL color to match your roofline. Internally, the hardwood can be factory-painted to match your interior décor or stained to showcase the natural grain, providing a bespoke luxury finish that uPVC cannot offer.

High-end architectural glazing is an investment. A Full Aluminum or Hybrid Hardwood lantern is viewed as a premium structural upgrade. Prospective buyers and surveyors instantly recognize the difference in quality, whereas a uPVC lantern is often seen as a "temporary" addition that will eventually need replacing.
