We are often asked what the difference between conservatories, greenhouses, and sunrooms are… but the distinction between each structure has evolved since the 18th century and as a result, the terminology used to describe these structures has changed – the key differences lie in the motivations behind their design. 

1. What is the design intent for conservatories and sunrooms?

Conservatories have very interesting architectural details that directly relate back to the conservatories from the 19^th Century – over 300 years of incredible history and elegant design...

Originally, the first orangeries were erected temporarily, using wood and south-facing windows to collect the light and warmth of the sun to promote plant propagation. As the availability of new materials became apparent in the nineteenth century, orangeries were built with less masonry and more glass to absorb the sunlight. From Kensington Palace’s classic orangery to Syon Park’s unique combination of orangery and conservatory, the evolution from orangeries to conservatories and greenhouses showcases true craftsmanship in their exposed details and decorative elements – this is what truly distinguishes them from sunrooms. Conservatory and greenhouse design harkens back to that Victorian ideal, very classical architecture and often very different from the rest of the house in a unique way. Their strict attention to detail and delicate craftsmanship creates a space unlike any other.

… Conservatories allow more freedom to create interesting design details and shapes. Sunrooms, on the other hand, you could design a square or rectangular addition and put a lot of windows in it, but there are no real interesting architectural details.

2. How will the conservatory, greenhouse or sunroom be used?

Today, we think of conservatories as “people spaces” – designed to create a suitable climate comfortable for humans to enjoy whether for gatherings, relaxation, or rejuvenation. They can be extensions of buildings that relate to the existing architecture but stand out or even stand alone in the gardens. Sunrooms are also “people spaces” but they typically are only simple extensions of the home. 

Greenhouses, on the other hand, are designed with plant health and propagation in mind. Whether utilitarian or more traditional in design, the goal is to promote heat gain. It often can resemble the look of a conservatory, but the motivation is to create a comfortable environment for plants.  To learn more about conservatories and greenhouses or to start conversations about building one for you or a client, give us a call at 410 479 4700!
