The Sapele Advantage

We exclusively use Sapele a high-density timber—because it outperforms Oak and Softwoods in stability and finish. It provides a furniture-grade finish that lasts 50+ years.

Solar Control Glazing

Reflects 78% of solar heat, ensuring your kitchen remains a comfortable living space 365 days a year.

Sarnafil Roof Covering

World-leading flat-roof membrane with a Full Guarantee against leaks.

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

Multipoint Security & PAS 24 Compliance: Your peace of mind is built-in. Every door and window aperture is equipped with high-grade, multipoint stainless steel locking systems designed to meet rigorous PAS 24 security standards.

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

Beyond the immediate lifestyle benefits, a bespoke hardwood orangery is a significant architectural investment. Unlike standard uPVC conservatories, our structures are designed as seamless, permanent additions that mirror the heritage of your original property. In high-demand areas like Windsor, Ascot, and Maidenhead, adding a high-specification, light-filled living kitchen or garden room can provide a substantial return on investment by increasing both the square footage and the aesthetic "kerb appeal" of your home.

Many of our projects fall under "Permitted Development," but Berkshire is home to many protected areas and Grade II listed buildings that require specialized expertise. We handle the entire architectural and planning process for you. Because we focus on "Architectural Grandeur" and use traditional timber details with Factory-Applied Teknos Finishes, our designs are often more looked upon favorably by local planning officers than modern, synthetic alternatives.

This is the core of our Material Excellence. Traditional hand-painting on-site is prone to weather interference, brush marks, and premature peeling. Our Teknos finishes are applied in a climate-controlled factory environment, ensuring every millimeter of the timber is sealed with a furniture-grade, microporous coating. This allows the wood to breathe while providing a shield against the elements, meaning your orangery won't look "tired" in a few years—it will retain its refined architectural detail for decades.

Absolutely. The "tired conservatory" of the past was often too hot in summer and too cold in winter. Our modern heritage orangeries utilize high-performance solar-control glazing and superior thermal insulation within the solid perimeter roof. Combined with the natural insulating properties of our sustainably sourced hardwoods, your new space becomes a temperature-regulated sanctuary perfect for a Christmas dinner or a mid-summer garden party.

We understand that minimal disruption is a priority for our Berkshire clients. A typical transformation—from the removal of your existing structure to the final handover of your architectural masterpiece—takes between 8 to 12 weeks on-site. Because we manage the entire project from design to installation without subcontracting, we can maintain a strict schedule and ensure our signature "Material Excellence" is present in every phase of the build.
