Orangery vs Conservatory vs Garden Room: Which One Is Right for Your Home?

If you’re looking to create more space at home, you’ve probably come across three popular options: conservatories, orangeries and garden rooms. While they can appear similar at first glance, each offers very different benefits depending on how you want to use the space and how you want it to feel within your home.

At Outside Interests, one of the most common questions we’re asked is: “Which one is right for us?” The answer usually comes down to lifestyle, budget and how connected you want the new space to feel to the rest of your property.

Conservatories: Bright, Open & Cost Effective

A conservatory remains a great option for homeowners wanting to introduce more natural light and additional living space without undertaking a full extension project.

Modern conservatories perform far better than older designs, with improved glazing and roofing systems helping to regulate temperature throughout the year. They are often the quickest and most cost-effective route to creating a brighter dining area, garden room or relaxed family space.

They work particularly well where:

  • You want to maximise light
  • You are working to a tighter budget
  • You want a stronger connection to the garden
  • The space will be used more casually or seasonally

One point that often surprises homeowners is that a conservatory can be exempt from Building Regulations, provided it meets certain criteria. For example, it must be under 30m², built at ground level, remain separated from the main house by external doors or windows, and have its own independent heating system. This is one of the key differences between a conservatory and an extension-style orangery.

Orangeries: The Best of Both Worlds

For many homeowners, the term “orangery” can be confusing. Modern orangeries often feature brick pillars, roof lanterns and large glazed areas, but in most cases they are technically classed as single-storey extensions and therefore require Building Regulations approval. Unlike a conservatory, they are typically connected to the home’s central heating, feature a solid roof and open directly into the main house.

With more solid structure, insulated sections and glazed roof lanterns, orangeries feel far more integrated with the main home while still bringing in plenty of natural light. They are especially popular for kitchen extensions and open-plan living spaces.

An orangery may suit you best if:

  • You want the space to feel like part of the original house
  • Year-round comfort is a priority
  • You are creating a kitchen, dining or family hub
  • You prefer a more substantial, premium feel

Garden Rooms: Flexible Space Away from the House

Unlike conservatories and orangeries, garden rooms are usually separate buildings positioned away from the main property.

Over the last few years, we’ve seen more homeowners investing in garden rooms not just as offices, but as gyms, hobby spaces, studios and places to switch off from busy home life. A well-built garden room creates valuable extra space without changing the footprint of the house itself.

Garden rooms are ideal if:

  • You want separation between work and home life
  • You need a multi-purpose space
  • You want to maximise garden potential
  • Privacy and flexibility are important

Planning Permission & Building Regulations

Planning permission and Building Regulations are often confused, but they’re two different things. Many conservatories, orangeries and garden rooms fall under permitted development, meaning planning permission may not be required. Building Regulations, however, depend on the type of structure being built. For example, qualifying conservatories are generally exempt, whereas most modern orangeries are treated as extensions and must comply with Building Regulations.

At Outside Interests, we guide clients through this process from the outset and advise on what is possible before any work begins.

Choosing the Right Option

There’s no universal “best” solution; it completely depends on how you want to live in the space.

Some homeowners prioritise light and affordability. Others want a seamless extension that feels fully integrated into the home. Some simply need practical extra space away from the main house.

That’s why we always start with the same thing: understanding how you want the space to function day to day.
