Thinking about adding a bright, characterful space to your home? One of the very first things on your mind is likely the budget. Getting to grips with orangery cost early on means you can plan sensibly, set a realistic initial budget, and move forward with confidence rather than guesswork.

At The Little Orangery Company, we’re firm believers in clear, straightforward advice. So in this guide, we’ll break down typical costs size by size, unpack the factors that shape the final price, and explain why a bespoke timber orangery is an investment that rewards you for decades to come.

Our range of bespoke spaces

First, a quick introduction. We’re specialists in beautifully bespoke, handcrafted extensions, working throughout Gloucestershire, Herefordshire, Worcestershire and across the wider South West. Our range includes:

Timber orangeries – luxury hardwood extensions that combine traditional craftsmanship with contemporary comfort
Timber conservatories – from Victorian and Edwardian to gable-ended, lean-to and P-shaped styles
Timber garden buildings – garden offices, studios and peaceful retreats
Oak porches and carports – striking structures that give your home a warm welcome

Because every project is made to measure, the cost of an orangery always reflects your individual choices. So let’s look at what those choices involve.

What goes into the cost of an orangery?

Several elements combine to shape your overall cost. Understanding these cost factors helps you see exactly where your money goes and where you might adjust to suit your budget.

The size of your orangery

The size of your orangery is the single biggest factor in the equation. A larger floor area means more materials, more labour costs and more building work. Costs are often calculated per square metre, which makes it simpler to weigh up your options as your plans develop.

Your choice of materials

The choice of materials has a significant impact on the figures. We build using premium hardwoods including Oak, Sapele, Idigbo and Accoya, and your selected frame material, glazing and internal finishes all play their part. Beautiful, durable materials cost more upfront but stand the test of time.

Glazing and thermal performance

Glazing influences both comfort and cost. Options such as triple glazing and solar-control glass improve thermal performance, keeping your new room cosy in winter and pleasant in summer. A higher specification costs a little more now but helps reduce running costs later.

The roof

The type of roof you choose can transform a space. A dramatic roof lantern or glazed lantern draws in light and adds height, while a sleek flat roof offers a clean, modern look. Both the roof lantern size and extras such as roof vents will affect your pricing.

Foundations and structural work

A quality orangery is a permanent extension, not a lightweight add-on, so it needs proper foundations to perform properly. The structural work involved, along with any additional work required to join your existing house, all feeds into the final price.

Bespoke features

Finishing details bring the whole design together. French doors, bifold doors or patio doors, decorative cornicing, pilasters and underfloor heating all add personality and warmth, while nudging the overall cost upward.

Orangery prices: a size-by-size guide

Every quote we provide is tailored to the individual project, so the breakdown below is a general guide rather than a fixed price list. Treat it as a useful rule of thumb, as design complexity and your specifications will ultimately shape the true average cost of an orangery for your home.

Compact orangery (around 9–12 m²) Ideal as a snug, breakfast room or reading retreat. With a smaller floor area and simpler structural requirements, this sits at the more accessible end of the price range.

Mid-sized orangery (around 15–20 m²) A favourite for kitchen-diners and family living. Adding a roof lantern, quality glazing and French doors will increase the investment accordingly, placing it in the mid range.

Large orangery (25 m² and above) A true statement space for open-plan living and entertaining. With greater design complexity, bifold doors, underfloor heating and premium touches, this sits at the upper end of orangery prices.

These are general guides only. The most accurate way to understand orangery prices for your property is a friendly, no-obligation chat with our team.

Keeping costs in check

If you’re working to a particular budget, there are plenty of ways to manage the cost of your orangery without compromising on quality. Opting for a slightly smaller floor area, choosing a more cost-effective timber, or selecting a simpler roof design rather than a large glazed lantern can all bring the figures down. You might also phase certain internal finishes, such as underfloor heating or bespoke joinery, adding them later as your budget allows.

The key is good planning from the outset. During your consultation, we’ll talk openly about your priorities and suggest where you can make savings while still achieving a beautiful, lasting result. That way, your finished orangery feels just right, both for your home and your budget.

What can make one orangery cost more than another?

Several factors influence orangery costs, including size, materials, design complexity, and additional features like heating or lighting. Customizations such as glass type and insulation level also play a significant role. Ultimately, the quality of construction and labour can greatly affect the overall price of your orangery project.

More than just an extension

Compared with a traditional extension, an orangery offers something special: an abundance of natural light, timeless character and a genuine sense of occasion. Built to last 50 years or more, it’s a permanent extension that can add real value to your home while giving you a room you’ll truly enjoy.

When you choose us, you get one dedicated point of contact overseeing the entire orangery project, from design and building regulations to foundations, glazing and the finishing touches. We manage the planning process on your behalf, including projects within conservation areas, so you’re never left coordinating multiple contractors.
