Oak orangery

Exquisite oak frame extensions for a light and airy ambience


Combine age-old craftsmanship with your own contemporary style

A Mitre Oak orangery provides a striking and versatile extension to any traditional or contemporary home. You can invite more light into the ground level without obstructing the view from your upstairs windows.

Originally built in the 1700s to shelter tropical fruit trees in the winter, all our orangeries feature elegantly glazed oak frames and characteristic lantern windows beneath a mansard roof.

We encourage our clients to choose from a superior selection of handcrafted windows and doors (Bi-fold, French, Single) to complete their bespoke oak orangery design and construction.

Additional information about our orangeries

What is an orangery?

People now use orangery-style rooms as relaxing spaces that overlook the garden from the inside. Traditionally, an orangery is a room dedicated to protecting fruit trees in the UK during the winter. However, now a contemporary orangery may be redefined as an extension with large windows and a flat roof.  

Do you need planning permission for an orangery?

An orangery falls under the category of a single-storey extension and is exempt from planning permission subject to the following:

- The orangery does not sit forward of the principal elevation.

- When within 2m of any boundary, the eaves cannot be higher than 3m, and no more than 4m in height.

- Rear extensions – no more than 4m in depth (detached home) or 3m in depth (semi-detached or terrace)

Side extensions – the width of the extension must not be greater than half the width of the original dwelling.  

Side extensions are not permitted on Article 1(5) Land (AONB, Conservation Areas)

How much does an orangery cost?

The cost of your oak orangery will depend on the size and complexity of its structure. However, most orangeries will be cheaper than a typical single-story extension and suit people who want to enjoy an open-plan living interior.  

Does an orangery add value?

Like any extension that is well constructed, temperature regulated, and aesthetically pleasing, orangeries will undoubtedly add value to your home.
