What is an Orangery and How Much Do They Cost?

If you’re wondering how much it costs to build an orangery in the UK, this recently updated price guide is for you.

The world’s most famous encyclopedia describes an orangery as a room or a dedicated building on the grounds of fashionable residences from the 17th to the 19th centuries.

These bright rooms were used to store citrus trees through the winter months.

Modern orangeries are somewhere between a conservatory and a house extension with bright elegance the primary theme.

Typically constructed with a brick base, plenty of windows and often with a central lantern-style roof design, orangeries are a step up compared to a framed conservatory.

Our 2018 Orangery Price Guide

In 2018 we asked 6 installers to provide us with a price to construct an orangery to the rear of our property in Surrey.

Key Points of Our Project:

As every build is different and we don’t want to compare apples to oranges, here are the key points of our proposed build:

  • the property is in Surrey – one of the most expensive counties to live in where land prices are at a premium
  • 18 square metres
  • flat roof with a lantern roof panel
  • finished to a good standard with timber frames and double glazing
  • plumbing, electrics, lighting, decorating, groundworks and landscape finishing all included
  • the wall is to be removed, creating an open plan orangery, rather than having a door leading into the room
  • VAT is included

Below is an average of all the figures given to us by our chosen 6 installers:

Why Are Orangeries So Expensive?

The amount of work required to build a custom orangery is similar to that of a ground floor extension but usually requires more expensive materials such as glass roof panels.

A well planned and built orangery will feel like a bright and practical part of the home.

Off-the-shelf conservatories are often seen as bolted-on rooms, too cold in the winter, too warm in the summer and rarely used as a practical room.

Orangery Prices Compared to Conservatories and Extensions

From our previous research into conservatories and house extensions, we know that the average cost of a conservatory to be around £11,000.

House extensions come in at around £1500 per square metre of floor space.

Orangeries are more expensive at around £2250 per square metre, depending on the size of the project, location, build quality and the amount of internal remodelling of the home that’s required.

How to Reduce The Cost of an Orangery

Not every orangery is custom built with many cheaper off-the-shelf designs available.

Also, consider:

  • Upvc frames are cheaper than wood
  • white Upvc frames are always cheaper than woodgrain brown Upvc frames
  • polycarbonate roof panels can cut the cost considerably as glass is very expensive
  • keep the size and location of the build within “permitted development” rules and you won’t need to apply for costly planning permission
  • knocking through a wall to open up the space between the existing home and the orangery is the preferred option for most builds but adds cost

For over four years we’ve been researching home prices in the UK.

From small jobs like electrical additions and plumbing repairs to larger projects such as extensions:

Garage conversions are one of the cheapest ways to extend a home. The walls and foundations and already in place and most of the work is internal.

Loft conversions are a great way to create an extra bedroom and are one of the east disruptive projects as most of the work is done via the roof.

Conservatories are cheaper than orangeries and extensions, are pre-fabricated and quick to erect.  Swap the glass or plastic roof panels and you’ll have a conservatory that looks and feels like an extension.

Single and double storey extensions can add considerable value to any home. If the build is within “permitted planning” rules, you won’t need costly or time-consuming planning permission either.
