Garden rooms have become an extremely popular option when looking to add space to a home. If you’re in the process of considering, you may be doing quite a bit of research such as the types of garden rooms, information on planning permission, and more.
Have you come across words and terms that are unfamiliar? If so, you’re not alone! It can be overwhelming to all of a sudden become inundated with construction and building terms. For this reason, we’ve created a glossary of some of the most common terms used for garden room home additions.
The Difference Between a Garden Room and an Orangery
First, we’ll start out by looking at the difference between a garden room and an orangery. Do you know the differences between these terms?
Orangery: these were once literally rooms built to grow orange trees, back in the 17th to 19th centuries. These days, however, this is a building constructed with semi-glazed walls, and a roof that has a “lantern” built on top of flat area of the roof. The lantern’s job is to let more natural light into the room. While these rooms don’t include as much glazing as a conservatory, the space is meant to be both light and airy.
Conservatory: this is a room built mostly of glazing. They tend to end up being very hot and stuffy in the summer, and too cold in the winter. Even so, there are ways to overcome these issues by improving circulation of air inside with roof vents, the addition of underfloor heating and solar control glazing to make the room cooler in summer.
Garden room: is usually similar to an orangery and uses semi-glazed walls. However, the roof is usually made of tiles, unlike an orangery. The garden room may also be built to match a home’s architectural style, unlike an orangery or a conservatory.
So, these are the differences between some of the most common types of buildings added to a garden! Now, let’s get started on the glossary!
