Conservatory & Orangery
Extensions in Somerset
We specialise in high-spec conservatories and orangeries that combine the aesthetic of glass with the thermal performance of a traditional extension. Whether you want a traditional timber-framed conservatory or a grand masonry orangery, our team ensures a seamless build from the foundations to the final decorative joinery.
Conservatory or Orangery:
Which is Right for You?
While both conservatories and orangeries focus on bringing the
outside in, they offer different architectural styles and feels.

Bespoke Orangeries
An orangery is the perfect middle ground between a conservatory and a full house extension. Characterised by more substantial brickwork pillars and a flat roof with a central “lantern” glass light, orangeries provide a more private, premium feel.

Custom Conservatories
Conservatories have evolved far beyond the draughty glass boxes of past. We build high-performance structures with dwarf walls and advanced thermal glass, ensuring the room remains cool in the summer and warm in the winter for year-round comfort.
We provide a comprehensive ground-to-handover service when it comes to our orangery and
conservatory extensions in Somerset and across the South West.

Structural Groundworks
Our in-house civil engineering team manages site clearance, drainage, and foundations to ensure the structure never shifts or cracks.

Hamstone & Local Masonry
We are experts in matching local Somerset stone and brickwork to ensure your orangery extension looks original to the house.

Solid Roof Replacements
We can replace tired polycarbonate roofs with high-performance tiled or solid roofs to make the room usable 365 days a year.

Internal Joinery & Finishing
From bespoke skirting and flooring to integrated lighting and heating, our carpenters and tradesmen finish the interior to primary-residence standards.
Frequently Asked Questions
An orangery typically features more masonry (brick or stone) and a flat roof perimeter with a central glass lantern. A conservatory usually has more glass surface area and a pitched roof that is entirely glazed. Orangeries often feel more like a natural extension of the house’s original architecture.
Yes. By using modern insulated bases and high-performance A-rated glass, we ensure that the thermal “creep” is minimised. When combined with underfloor heating, your conservatory becomes a comfortable room regardless of the Somerset weather.
Most conservatories and orangeries fall under Permitted Development, provided they meet certain size and height limits. However, if you live in a listed building or a Conservation Area, specific consents are required. We have nearly 40 years of experience navigating local planning and will guide you through every step.
A standard high-spec conservatory or orangery extension in Somerset typically takes between 6 to 10 weeks to complete, depending on the complexity of the masonry and the groundworks involved.
