The average cost of an orangery in the UK typically ranges from £20,000 to £60,000, depending on the size of the extension, materials used, and the complexity of the design. Smaller orangeries can cost less, while larger bespoke structures with roof lanterns and premium glazing increase the overall price.
Average Orangery Cost in the UK by Size
| Orangery Size | Typical Cost with Installation (2026) |
|---|---|
| Small Orangery | £20,000 – £30,000 |
| Medium Orangery | £30,000 – £45,000 |
| Large Orangery | £45,000 – £60,000+ |
Historically installed as greenhouses for fruit trees, today’s orangeries are a luxurious and elegant hybrid that brings together the advantages of a home extension and a conservatory.
Often featuring glass on both walls and ceilings, these spaces are beautiful, flooded with natural light, and suitable for year-round use.
At Creating Spaces, we design and build every imaginable orangery style and size, from traditional to contemporary and lantern-style constructions. By combining high ceilings with advanced thermal technology, we create elegant, comfortable spaces.
Average Orangery Cost Per m² in the UK in 2026
Every orangery is different, which is part of the charm of this unique construction, and it is always difficult to estimate an average price with accuracy when individual choices and parameters are taken into consideration.
The cost of an orangery per square meter (m2) can vary significantly, typically ranging from £1,250 to £2,500 with the overall orangery cost upwards of £20,000 based on an orangery measuring twenty square metres. This average orangery square metre cost includes the supply and installation of the orangery components as well as electrics, plastering and labour. Factors like size, materials, and design complexity all influence the final price.
People visiting the Creating Spaces showroom often ask the following questions, which we will address here.
- What are the average costs?
- What’s involved in the process?
- How long will it take?
- Will it be worth it, and will it add value to my home?
The orangery cost will vary depending on the size, the style chosen, and the options included. How the orangery adjoins the existing building will also impact the cost.
General Size Made From Estimated Price
Typically, a bespoke UPVC / Timber orangery will cost over £30,000.
A medium UPVC / Timber orangery will start at £30,000+.
It’s a great investment in your home, adding both value and aesthetic appeal, giving you a new room, and more living space and providing a beautiful room for relaxation and entertaining.
Research suggests property value will be enhanced by between 5% and 10%, and a very high-quality example could add as much as 15%.
What affects the cost of an orangery?
So which factors most affect orangery prices and the final installed cost?
From size to design, location, interior styling, landscaping, planning permission requirements, individual budgets and finishes, many different aspects will influence the price you pay for your finished orangery extension and enable it to integrate seamlessly with your home.
Size of the extension
The most important consideration – a large orangery will mean a greater overall cost for materials and labour. It will be your size specification that has a significant impact on the eventual orangery cost.
Wall material
The design and location of the orangery will help to determine the wall style, ranging from brick to fully glazed or dwarf walls. Larger areas of glazing usually mean lower cost, but this is not always the case.
Window & Door Frame materials and style
UPVC is a more cost-effective alternative than traditional timber for your orangery, but your decision may be influenced by your design choices in terms of orangery costs; a more traditional design may favour wood, with contemporary options matching well with UPVC. Adding features such as large bifold doors and hardwood windows will up the total cost. Aluminium glazing options are also available.
Roof design
The roof style selected for your orangery will also significantly impact the overall price. It’s the one thing that stylises the design, differentiates it from a simple conservatory roof and adds to the unique character of this construction. It will also affect the thermal efficiency of the living spaces.
Creating Spaces specialises in designing orangeries featuring individual roof lanterns as integral sections in flat roof designs, or a design where the entire roof is a single glass lantern.
It’s also important to install roof vents in the roof lantern to ensure the space is well-ventilated in summer weather.
Foundations and groundwork
Every property is different, every site varies and there will always be site-specific issues. Uneven terrain and poor-quality soil conditions can add to the cost, and laying a concrete slab for foundations is a time-consuming task.
On average, the groundwork for proper foundations for orangeries can cost upwards of £4,000. At Creating Spaces, we always assess to determine what will be required before building work commences.
Insulation
Including optimum levels of insulation for roofs, walls and floors may increase orangery prices, but will pay off in the long run with a more energy-efficient space all year round. The orangery depends on excellent levels of insulation for comfort in all seasons.
Additional costs
When you’re considering the cost of a new orangery project, there is a whole list of considerations that may be considered extras by your contractor, such as:-
- Plastering
- Insulation
- Lighting
- Heating
- Electrical sockets and electrical installations
- Ventilation
- Internal pelmets
- Cornices to hide guttering
- Interior finishes
Remember you may need to factor in the cost of landscaping in terms of remedial work in the garden, as well as extra touches that may increase orangery costs but will help to make your orangery both special and unique.

Orangery vs Conservatory Cost Comparison
An orangery is a more complex structure than a simple conservatory, which is usually made up using UPVC frames and double-glazed units.
An orangery will usually include traditional building systems, as well as glazed units and more challenging structural requirements that must adhere to building regulations on roof lantern options and structural support.
This typically increases the cost of orangery design and build.
| Feature | Orangery | Conservatory |
|---|---|---|
| Typical Cost | £20k–£60k | £6.5k–£25k |
| Structure | Brick + glazing | Mostly glass |
| Insulation | High | Lower |
| Year-round usability | Excellent | Moderate |

Is planning permission required?
Orangeries are generally considered to fall within permitted development, meaning planning permission is not required. However, it is always worth seeking advice from your local planning office to ensure your proposed orangery extension complies with the basic requirements.
- It must not span more than half the width of your existing home
- It must not cover more than 50% of the land which surrounds your home
- You may not include balconies or raised platforms
- It must not be more than four metres high
- Additional regulations may apply if it is situated within two metres of your boundary.
How long does an orangery take to build?
There are several different stages involved in deciding to add an orangery as an extension to your home.
- Initial consultation – at Creating Spaces, we discuss our customers’ individual preferences and choices in detail, examining the design potential, feasibility, and cost implications of the project.
- Design process – the production of more detailed plans for the orangery installation.
- Practicalities – if required, the time involved in obtaining planning permission is dependent upon your geographical location, your existing property and the proposed site of the orangery.
Once all the formalities are complete, the groundwork can begin. Again, this will depend on each property and site.
We then move to the construction phase. Again, this is a size and detail-dependent process – a larger, more complex orangery will take longer to build than a smaller, more basic structure. Walls will be built, and glazing and roofing will be installed.
Then it’s time for the finishing touches, including internal electrics, plastering, flooring and internal decorations.
Timescales are notoriously difficult to predict with accuracy, as they can be affected by many different variables, including weather which can add to orangery costs. However, the process from initial consultation through to the completed build can take anywhere from six to twelve weeks, or longer. Expect to have contractors on site for a minimum of two weeks.
Summary
Achieving a result that matches your aspirations is critical, and it’s important to understand that price is never the only factor, and making the cost of an orangery cheaper will probably not yield the best results. Particularly with a high-impact addition to your home, like a dream orangery extension, choosing the cheapest option may not be the best route in the end, given the potential added value and wow factor.
Remember, many companies, including Creating Spaces Group, also offer finance options. This means you can spread costs over a longer period or choose to buy now and pay later. This means you don’t need to cut corners when it comes to specification.
Reputation
It’s also vital to consider the contractor’s reputation when choosing to design and build your orangery. Look at their accreditations and their track record. The warranty they offer on the finished orangery should also significantly influence your final decision.

FAQs
The average cost of an orangery in the UK typically ranges from £20,000 to £60,000+, depending on size, materials, glazing options and whether structural work is required. Larger bespoke designs or premium finishes can increase the overall cost.
The main factors influencing orangery costs include:
Size and layout
Brickwork and roof design
Glazing and insulation levels
Foundations and ground preparation
Doors, windows and finishing options
In many cases, an orangery can be more affordable than a full extension, as it combines brickwork with larger glazed areas. However, costs vary depending on design complexity and building regulation requirements.
Many orangeries fall under permitted development rights, but planning permission may be required depending on size, height and property location. A professional installer can advise based on your specific project.
Most orangery projects take 4–8 weeks to build, though the time from the initial consultation can be 6-12 weeks depending on complexity, weather conditions and preparation work such as foundations or structural openings.
