A Lean-To conservatory is simple and modern. It has a flat roof that leans against the wall of your conservatory. This type is remarkable for small spaces and works perfectly with any design of home. It’s regularly the most affordable choice.
Victorian Conservatory
The Victorian conservatory is elegant and classic. It has a rounded form with huge home windows that allow plenty of light. Its stunning design makes it a popular choice. This form of conservatory provides charm and style to your home.
Edwardian Conservatory
The Edwardian conservatory is much like the Victorian but has a rectangular or square shape. This makes it very sensible, as you could use all the internal space. It’s an amazing mix of beauty and function.
Gable-Front Conservatory
A Gable-Front conservatory has a high, pointed roof. It is big in size and allows plenty of light to come in. The tall roof makes the room feel bigger and gives it a bright, aesthetic feeling.
P-Shaped Conservatory
The P-Shaped conservatory combines two styles, usually a Lean-To and a Victorian. It’s huge and may be used as two separate areas. This kind is perfect if you need more room for different activities.
T-Shaped Conservatory
A T-shaped conservatory has a central area that extends out, forming a “T” shape. It offers a lot of space and is right for large homes. This style creates a beautiful, open place that feels like a natural extension of your home.
Orangery
An Orangery is a combination of a conservatory and a traditional room. It has more brickwork and a solid roof with glass panels. Orangeries feel more like an extra room in your home. They are elegant and offer more privacy.
