Lantern Roof Conservatory Cost

The average price of a lantern roof for a conservatory is in the range of around £2,000 – £6,000.

This cost is determined by a number of factors: there is no standard size and design for a lantern roof.

All of our lantern roof designs feature a complete water-tight design with aluminium frames and double glazing, but a larger conservatory extension will require a larger and more expensive lantern roof.

Similarly, we offer a number of solar control glazing options for lantern roof conservatories.

Other additional options include a decorative cornice, stormshield protection, and additional solar control glazing to protect your living space from excess heat.

For a quote for the costs of your chosen design for lantern roof conservatories, whether that is just a simple basic design or a fully featured model with solar control glazing and a decorative cornice mould, just get in touch with us through our website.

Types of Roof Lanterns

There are several different types of lantern roof conservatories available for your home. Let’s take a look at some of the most popular design options.


A rectangular lantern conservatory roof is typically placed in the centre of the room, drawing emphasis to a specific area of the space.


If space is limited, you may have to be careful with your lantern conservatory roof selection. As a result, you may wind up with a square lantern roof.


An octagonal lantern roof is a great choice for larger spaces. They require more glass panes but allow light into your living space from a wider range of angles.

An octagonal roof conservatory is ideal for a big living space in need of additional light in an energy-efficient manner.


A cupola lantern roof conservatory is not the best option for maximising light, but it offers a classy and refined design and excellent thermal performance.

This style minimises heat loss and offers a premium style for that all-important finishing touch.

Double and Triple Lanterns

It is possible to create stacks of two or more lanterns reaching up into the sky for a high-performance design with a bit of extra space and style for larger conservatories.

This uses a lot of glass and does not work so well at the ridge end of a building, but it gives a great look and can be combined with the best of our unique stormshield protection to keep your glass roof safe.


Maximising heat retention to lower your heating bills in winter is great, but it is often worth adding ventilation that can be opened in the summer.

A lantern roof conservatory can get hot in the sun, and it is worth doing what you can to create a comfortable living space in your extension in any weather.


Finials are simply a decorative detail put on the top of your glass roof. They come in a number of designs but are not an essential part of a conservatory roof structure like an internal pelmet!

What is an Orangery Roof Lantern?

An orangery lantern roof, or lantern roof conservatory, is a beautiful alternative to flat glass for conservatories that gives depth to your house with an eye-catching feature.

A lantern conservatory roof guarantees that light enters the room in the way you want it to, whether you have a full glass conservatory or a bricked home extension.
