Looking to add an orangery to your home? 

Orangeries – notably different to conservatories – are the perfect hybrid between a conservatory and an extension in terms of brickwork, offering the benefits of a room that could be used all year round but blended with an abundance of natural light.

They’re popular, versatile choices, allowing you to create office spaces, lounges, sitting rooms and more as an extension of your home. So… how much is an orangery going to cost?

Here at West Midlands Double Glazing, we have over two decades of experience in the home improvements industry. Not only that, but we’re the only company in the West Midlands that can provide 20-year finance options for any orangery project. 

This can enable you to spread the cost in monthly instalments over two decades, making your dream renovations more affordable than they’ve ever been before!

While the cost of building an orangery is unique to you and your home, we’re here to guide you on what type of budget you’ll need, helping you make your decision with more clarity and understanding of all the considerations. 

While this blog acts as a guideline, prices are determined by project size, design and build complexity, which we can determine after conducting a site visit. We recommend booking in with us for a FREE consultation visit in order to provide an accurate quote – contact us today to arrange.

Orangery Prices 2025

In the UK, the average cost of an orangery is around £25,000 to £45,000, with the average working out to be around £35,000, based on modern requirements.

Of course, the exact figure will depend on the choices you make along the way. Everything from the footprint to the glazing, the type of roof and even your choice of flooring can influence the final price.

We’ve put together the most important considerations that will affect the cost of your orangery build:

• Size
• Style
• Roof type
• Materials
• Windows, floors & doors
• Additional extras

So, the question of “how much is an orangery” isn’t a simple answer – it involves identifying what the priorities are for your new room, and making a few decisions regarding its build.

In this guide, we’ll walk you through all the key cost considerations, so you can plan your orangery project with confidence.

Size

The size of your orangery is often the single biggest factor in determining how much it will cost. Quite simply, the larger the footprint, the more materials and labour are required – from extra brickwork and glazing through to foundations, heating and electrics.

But cost isn’t the only reason to think carefully about size. The footprint you choose will also shape how the orangery fits into your home and garden, and what you’ll be able to use the space for.

Here’s a quick guide to typical sizes and what they might cost in 2025:

Size	Typical Dimensions	Best For…
Small	3m x 3m to 3.5m x 3.5m	A cosy reading space, snug or breakfast corner
Medium	4m x 3m to 4m x 4m	A dining room, home office or lounge area
Large	5m x 4m to 6m+ wide	An open-plan kitchen/diner or multi-use living space
Bespoke	7m+ width or wrap-around	A fully customised design to mirror a traditional extension

It’s worth remembering that larger orangeries can also bring extra requirements such as deeper foundations, additional structural reinforcements, or even planning permission. While these add to the budget, they also ensure your orangery is safe, comfortable and perfectly integrated with your home.

Style & Layout

The style you decide on for your orangery will largely influence your price range, so it’s important to consider how the room will be used before designing your layout. And one of the biggest appeals of an orangery is its flexibility in style. Unlike conservatories, which are often more “off the shelf”, orangeries are usually more bespoke, which means you can tailor the look and layout to suit both your property and your lifestyle.

For example, kitchen orangeries or dining room spaces are popular choices, combining cooking, dining and socialising in a bright, airy space.

A classic orangery typically features brick or stone pillars, a flat roof with a central lantern and a balanced, symmetrical look. This is a timeless style that blends seamlessly with many types of homes.

Whereas, a more modern orangery could feature flat lanteen roof styling, clean brickwork and modern bi-folding doors to bring the garden inside as an extension of the home. These designs tend to cost more because of the higher-spec materials, but they create a striking, modern finish.

Roof Type

The roof is one of the most defining features of an orangery. While conservatories are usually fully glazed, an orangery tends to have a solid, flat roof with one or more roof lanterns to let natural light flood in.

A single, central lantern is the most traditional and cost-effective option, giving you that signature orangery feel. If you want to make more of a statement, you could opt for multiple lanterns across a larger roof, though this does require more structural work and, therefore, increases the price.

Some homeowners prefer a more contemporary look, such as a flat roof with skylights or a hybrid design that combines solid insulated panels with glazed sections. These can offer the best of both worlds: excellent insulation with plenty of daylight.

Whichever option you choose, the roof will have a significant impact not just on cost, but on the comfort and usability of the room throughout the year.

Materials

Another important factor in the overall price of your orangery is the choice of materials. Because orangeries are designed to feel more like a permanent extension, the brickwork and frames you choose need to complement your existing property.

• Brickwork: Most people choose bricks that closely match their house for a seamless look, but opting for premium bricks or natural stone can quickly increase costs.

• Frames:
  • uPVC is the most budget-friendly, easy to maintain and available in different finishes.
  • Aluminium gives a sleek, modern look with slim but very strong frames, allowing for larger panes of glass.
  • Timber is perfect for traditional homes and provides excellent insulation, but it’s the most expensive option and does require regular upkeep. It’s for this reason that we don’t supply timber materials here at WMDG.

• Glazing: Standard double glazing is included as a minimum, but upgrades such as solar-control glass, triple glazing or even self-cleaning glass will add to the cost while improving comfort and reducing maintenance.

Choosing the right materials is about more than just budget. They also determine the long-term performance of your orangery and how well it blends into the rest of your home.

Windows, Doors & Floors

How your orangery is designed is what makes the difference between a room that’s usable year-round and one that feels too hot in summer or freezing cold in winter. This also has a significant impact on the overall cost.

• Window glazing

Double or triple glazing will keep the space warm in winter, while solar-control glass can help to prevent overheating in summer. Adding blinds or roof shading is another consideration to keep out the heat of the sun, both for comfort and cost.

• Floors

Wooden floors may feel a little chillier underfoot come winter, so insulating under the base could be a good way to keep heat locked in in the cooler months. Underfloor heating can also create a more comfortable, warmer environment.

Also, will you opt for luxury vinyl flooring? Or perhaps laminate? These types of flooring choices can often cost more than expected if not accounted for in the initial budget.

• Doors

Choosing what type of doors you’d like for your conservatory can also affect the cost. For example, whether you choose bi-folds or French doors, patio doors or a swing and slide, doors can affect how well your orangery blends in with your home and your garden.

Additional Extras

When planning an orangery build, it’s easy to focus on the visible elements like glazing, flooring or lighting. 

But there are a number of additional considerations behind the scenes that can have a big impact on the overall cost.

• Electrics

From spotlights and pendant lights to sufficient plug sockets and wiring for entertainment systems, electrical work can add more than you expect if not budgeted for in advance – so be sure to consider your requirements of the room beforehand.

• Heating & cooling

Radiators, underfloor heating, or even air conditioning may be necessary to make the orangery comfortable in every season, so it’s important to consider these in your budget from the get-go.

• Ventilation

Options such as roof vents, trickle vents or even mechanical systems improve airflow and prevent the room from feeling stuffy, but aren’t always included in basic quotes – so it’s important to consider what type of ventilation you’ll require.

• Built-in storage

Custom features such as integrated seating, shelves or cabinetry make the space more functional but also add to the price, so it’s best to consider them early if they’re an essential part of your orangery build.

• Foundations

Every orangery requires strong, stable foundations, and the cost of this stage can vary quite a lot. If the ground on your property is uneven, clay-heavy or close to large tree roots, deeper foundations may be required. Similarly, drainage work may also be necessary to prevent water problems later.

• Building regulations 

Orangeries need to comply with building regulations to ensure they are safe, energy-efficient and structurally sound. Building regulation approval comes with fees and sometimes additional work to bring the design in line with standards, but it also ensures your orangery adds genuine value to your home.

• Planning permissions

Many small orangeries fall under “permitted development rights,” meaning you won’t always need full planning permission. However, this depends on the size, height and location of your build. The application process itself has costs attached, and it can also extend your project timeline, so it’s important to account for this early on.

Is an Orangery Cheaper Than a Conservatory?

In most cases, an orangery will be more expensive than a conservatory. 

This is because orangeries are built with more substantial brickwork, flat insulated roofs and roof lanterns, which makes them feel more like a traditional extension than a lightweight glazed room. 

So while a conservatory is a more affordable option, an orangery provides a room that seamlessly blends in with the rest of your home, which can be used comfortably all year round. Learn how much a conservatory costs from our detailed guide.

Would an Orangery Add Value to my Property?

Yes – in most cases, a well-designed orangery will add value to your home. 

Because orangeries are seen as a more permanent, extension-like addition, they often appeal to buyers in the same way as a traditional brick-built extension.

On average, homeowners can expect an orangery to add around 5-20% to their property’s value, although the exact figure will depend on factors such as size, quality, and location.
