Orangery or Conservatory?

Orangeries have a long history dating back to the 17th Century, whereas conservatories were developed as a by-product. Conservatories are primarily made of glass to allow maximum natural light into the space. As conservatories tend to have more glass, they may be slightly warmer than orangeries on sunny days. Both types of structures add value to your home and provide a beautiful space to relax in, making them a popular choice among homeowners.

Conservatories have come a long way in the last decade. It used to be the case that they held heat in the Summer and got quite cold in the Winter months. Polycarbonate roof panels are a thing of the past. Most orangeries and conservatories now have active blue glass in the roof systems which really helps with heat loss and retention making the room useable and enjoyable all year round.


Celestial also install conservatory tiled roof systems such as Supalite roofs. They give a beautiful tiled look to the conservatory and again aid heat retention and loss.


Ultimately, whether you opt for a conservatory or an orangery, you can look forward to spending time in your new favourite room.

The Edwardian

Edwardian conservatories are incredibly popular due to their practicality and elegant rectangular or square design. The high roof style allows plenty of natural lighting to flood into the room making this design a favourite in both the summer and winter months. Normally square or rectangular available in a variety of sizes and finishes to complement your home.

The ‘P’ Victorian

The ‘P’ Victorian-style allows flexibility in styling and a classic presence whilst adding not only desired additional space to your home but a touch of class and value as well.

The Lean-to

Lean-to conservatories are usually an elegant glass square or rectangular design, with a classic pitched roof system. They are the ultimate design for smaller spaces and perfect for bringing your garden and the outside world into your home or where a little additional space is needed.


The Victorian

The Victorian is the most desirable option available, with ornate cresting, sharp-angled roofing and a rich highly valued design. The Victorian design is just right for anyone seeking additional spacing in their home in a classic and elegant style.

The Orangery

These attractive living spaces offer that little bit more to your home. Similar to a conservatory, an Orangery gives the additional benefits of space and light – however, there is a difference in its construction. Rather than using PVCu frames as walls, Orangery walls are brick built – with a PVCu roof structure.
