Our orangeries are a luxurious extension option for any home. They can be customised to suit almost any style and are available in a range of colours. Our timber frames offer a timeless elegance with a modern, efficient performance.  

By crafting our orangery glazing frames from the highest quality timber, we can ensure a highly durable finish, perfect for the harsh and wet British climate. Our orangeries can be finished in a range of lacquers and paints to suit the project requirements.

Our hardwood timber frames are highly insulating and, when paired with a double or triple glazed unit these timber frames offer excellent thermal insulation.

Our Orangeries…

  1. are completely designed and built by us
  2. can include double or triple glazing

Our timber orangeries are available to be made from any of the three below timbers:

Engineered Hardwood

Our engineered hardwood is extremely robust and offers a long life expectancy.


Accoya is expertly treated to create an extremely hard wood, even harder than Oak. It carries an elongated warranty of 25 years.


A beautiful timber species which offers an elegant pattern. Is available painted but we recommend lacquer to make the most of the timber pattern

Lantern Rooflights

Lantern rooflights are a versatile way of maximising the amount of natural light entering a single-storey living space. Perfect for use on flat roofs, our lantern rooflights feature elegant timber glazing bars for a traditional or contemporary design. 

Available in range of bespoke sizes and shapes tailored to your project, with a high thermal performance to keep your orangery at a comfortable temperature all year round.

Glass Options

Our timber sash windows are made with double glazing as standard. Our double-glazed units are extremely well insulating and include a low e coating and argon gas filling as standard. You will typically achieve a Ug value of 1.1 W/m2K.

For higher levels of thermal performance our timber frames can be designed to take a thicker triple glazed unit. 

Additional glass options such as solar control coatings, decorative glass, translucent glass, low iron glass and low maintenance glass are all possible.

Planning Permission

As a rule, single-storey extensions to the rear of a home don’t tend to require planning permission, as long as:

  1. They extend beyond the rear of the main building by less than 6m for a semi-detached, or 8m for a detached home
  2. They are less than 4m in height

However, you may need permission if your home is a listed building. 

In addition, building regulation approval is required on any work.


Cleaning & Maintenance

Each orangery timber window and door from Belgravia Hardwood is designed for minimal maintenance over its lifetime. We create hardwood frames that are easy to live with and work with. 

The exact maintenance required for your timber orangery will depend on the timber species you choose, the finish chosen and the environment it is installed in.
