Orangery roof lanterns

An orangery is defined by its roof: a solid flat or pitched perimeter with a glazed lantern in the middle. The lantern supplies the light, while the solid surround keeps the room warmer in winter and cooler in summer than a fully glazed conservatory.

In short: The glazed centrepiece of an orangery roof, framed by a solid perimeter. Guide prices start from £1,295 including VAT, supply only.

How big should an orangery lantern be?

Designers usually leave a solid border of about 500–900 mm around the lantern, wide enough for an internal pelmet with downlights. For a 4 × 3 m orangery that typically means a lantern of around 2000 × 3000 mm.

Mind the glazing allowance: an orangery with glazed walls and a big lantern can exceed the 25% glazing guideline that applies to extensions in England, which then needs energy calculations to show compliance.

Converting a conservatory into an orangery

A common project replaces a fully glazed conservatory roof with a solid roof and a central lantern. The lantern is then supplied to suit the new upstand built into the solid roof. If you are doing this, check with building control: replacing a conservatory roof with a solid one often changes the building regulations position.

What does an orangery lantern cost?

Guide prices below include VAT. Traditional detailing with cresting and finials suits period orangeries.

Before you order

Three checks

  1. Measure the outside of the kerb, width then length, and check the diagonals. How to measure.
  2. Check the glazing allowance for your extension and whether you need planning permission. See building regulations and planning.
  3. Plan the lift. Your quote gives the approximate weight so your installer can plan access and lifting.
Questions

Orangery roof lanterns: common questions

What is the difference between an orangery and a conservatory?

A conservatory has a mostly glazed roof; an orangery has a mostly solid roof with a lantern in the middle and usually more solid wall. Orangeries are easier to keep comfortable year round.

Can I add a lantern to my existing orangery roof?

If the roof has a suitable opening and upstand, yes. If not, the roof needs structural alteration first, which is a job for a builder with an engineer's input.

Should the lantern match my bifold doors?

A common choice is to match the outside colour, often anthracite. The inside can be white to keep the ceiling bright.

Do orangery lanterns come with cresting?

They can. Cresting and finials are options on traditional ranges.
