A conservatory is the ideal spot to unwind or entertain.
A versatile classic.
Picture a conservatory and you'll probably see a Victorian-style construction.
It's a versatile build that complements both period properties and new builds. With its bay front, pitched roof and ridge details, the Victorian-style conservatory adds space and class to any property.
But while it's Victorian in name, it's modern in design – harnessing modern materials designed for longevity and thermal efficiency.
An attractive, brand-new living space.
Orangeries come in different styles, from the timeless to the cutting-edge. They give your property a touch of grandeur and can stay warm all year round.
Space-saving style.
Is your property vertically challenged? Lean-to conservatories are ideal for bungalows and houses with low eaves. Their low-pitched roofs mean they can be installed in smaller properties without any loss of "wow".
Need a lantern roof installed or replaced? They're perfect for conservatories, letting the light in and crowning your extension.

Absolutely! With energy-efficient glass, additional heating or insulated conservatory roofing, your conservatory should be a cosy spot all year round.
Generally speaking, no. If in doubt, check the government's council tax calculator.
An orangery is a brick building with a lantern roof and large windows – unlike a conservatory, which is a glass structure with a pitched, glazed roof.
A lean-to conservatory has a flatter, more slanted roof than a standard conservatory. They're typically installed in properties with low eaves such as bungalows.
A lantern roof is a glazed structure that lets natural light into your home from above. It differs from a rooflight in being three-dimensional. Our lantern roofs are Victorian in style but harness modern technologies to ensure thermal efficiency, sturdiness and security.
*Some models differ in warranty.
