When does a conservatory become an extension?

Conservatories quotes

When you are looking to expand your living space for various reasons, it’s always essential to check whether you are designing a conservatory or an extension. This is because there may be different legal requirements for permission to install them. We always advise you to check with your local authority or ask experts before you go ahead with any extension work on your property, but here are a few tips. 


Knowing The Purpose Of The Expansion

Before you start designing a new expansion to your property, let’s decide what the space will be used for. This will help you determine how far you need to expand and what it will be made of. 

For instance, conservatories are commonly known for their excellent floor space and flexibility. This is why conservatories are perfect for lounges or dining rooms, as you can fit larger items, such as tables, chairs or sofas, while still having space to move around. Your conservatory would be an extra room to entertain friends and family or be functional for everyday needs. 

However, a house extension can be tailored to any need. Considering the definition of ‘extension’ is to enlarge or prolong something, it makes sense for homeowners to use house extensions for functionality. Depending on the size or shape of your new house extension, it can be great for a home office or even a gym! 


Legal Classifications

The legal classifications of a house extension may be different depending on your local authority, but most councils will determine them on the following aspects:


  • Size and Proportion 
  • The type of property you own 
  • Whether any extras will be added 
  • The building materials being used 
  • Previous work on your property 
  • Other council restrictions on the property 


Once you know the final details of your designs, you can use your local council’s requirements to determine whether you have designed a conservatory or an extension. 


The Design

Though conservatories and house extensions look similar, they have unique features. This will help you determine whether your conservatory is actually a house extension. 



Conservatories are known for their higher glass-to-brick ratio compared to orangeries or house extensions. They will typically have a glass roof and large glass walls so you can look out at your garden. There are multiple different types of conservatories, such as Victorian, Lean-To, or Edwardian. These styles provide charm or elegance to the conservatory and significantly enhance the home’s visual appeal. You may opt for a gable conservatory, which is perfect for modern homes. 


House Extensions

House extensions are incredibly versatile and can look how you need them to. Because they are for expanding your home, they will typically have the same style and materials that your home uses, so they blend seamlessly. They may only expand on part of your home, or you may choose to extend the whole width of one side. Depending on what home improvement company you prefer, you may get different customisable options to make your house extension truly your own.
