Words from happy customers

Victorian-style conservatories

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.

Orangeries

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.

Lean-to conservatories

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".

The crowning feature.

Need a lantern roof installed or replaced? They're perfect for conservatories, letting the light in and crowning your extension.

Frequently asked questions

  • Are conservatories warm in winter?

    While your conservatory can get cold in the winter, you can install radiators, under-floor heating or a thermal conservatory roof to keep it toasty.


  • Can conservatory roof panels be replaced?

    Yes – you can replace your roof panels with glass, polycarbonate or tiles. We supply SupaLite roofing systems, which have a tiled look and deliver impressive energy efficiency.


  • Can conservatories be used in winter?

    Absolutely! With energy-efficient glass, additional heating or insulated conservatory roofing, your conservatory should be a cosy spot all year round.


  • Will a conservatory increase council tax?

    Generally speaking, no. If in doubt, check the government's council tax calculator.

  • What is an orangery?

    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.

  • What is a lean-to conservatory?

    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.


  • What is a lantern roof?

    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.
