Imagine a beautiful orangery extension or house extension — a seamless blend of elegant architecture, natural light, and comfortable living space.
Originally inspired by the classic conservatories of grand estates, today’s orangery extensions are designed and built by skilled orangery builders and contractors using solid brickwork, timber, and the latest construction technologies.
Unlike traditional glass structures, a modern orangery extension offers the look and feel of a permanent room — perfect for open-plan kitchens, sun-filled lounges, or elegant dining spaces.
Creative and highly customisable, orangery construction allows your home to truly shine.
But we don’t just specialise in orangery extensions.
If you are looking for something even more substantial, discover our wide range of home extension solutions — including rear extensions, side returns, double-storey builds, and loft conversions — each designed to perfectly complement your home and lifestyle.

Typically, an orangery extension is a brick-based structure joined to the rear or the side of a property. Usually, the joining door or wall is taken out so the house and orangery extension flow naturally together. The most common layout is having one or both full-height walls to the sides, providing wall space for seating, radiators, or artwork. It is common to have a predetermined window layout to the front and/or side, with a central set of French doors or Bi-folding doors.
The roof is often a flat roof with a covering of either rubber EPDM membrane or fibreglass. Most previous customers have chosen to have a large roof lantern in the centre, featuring an aluminium frame (available in different colours) and self-cleaning glass. The options are endless regarding the external and internal design. We at building company River.ODP are always on hand to guide you in any decisions or answer any questions.
If you are considering an orangery extension, orangery builders and orangery constructors can provide expert advice and services to bring your vision to life. Working with a reputable building company ensures that your orangery is constructed to the highest standards, combining functionality and aesthetic appeal. Whether you need contractors for the initial construction or ongoing support, orangeries builders are dedicated to delivering exceptional results.
The cost of building a bespoke orangery extension can vary depending on a number of factors, including the size, design complexity, materials used, and any additional features such as underfloor heating, bi-fold doors, or roof lanterns.
On average, you can expect prices to start from £25,000 to £35,000 for a smaller, straightforward orangery extension. Larger, high-specification projects with luxury finishes can exceed £50,000 or more. Every orangery extension we design is tailored to our client’s needs, which is why we always recommend a free consultation and quote to provide an accurate estimate based on your exact requirements.
A beautiful orangery extension is not just an investment in extra space — it’s a smart way to increase the overall value of your home, offering a stunning and functional addition that enhances everyday living.

For a versatile, light-filled space you can enjoy all year round, an orangery extension is an excellent choice. Offering superior thermal insulation with its brick walls, an orangery combines the comfort of a living room with the openness and brightness of a conservatory.
At River.ODP, a leading building company specializing in orangery extension construction, we offer a variety of popular styles to suit different tastes and needs. Our experienced orangery builders and contractors are adept at creating bespoke designs that enhance the beauty and functionality of your home. We work closely with the best architects and designers to ensure each orangery extension is unique and tailored to your specifications. Here are some popular styles of orangeries we offer:
At River.ODP, our traditional orangeries draw inspiration from classical architecture. We focus on elegant elements such as columns, pilasters, and intricate details that lend a timeless charm to your space. Our orangery design includes solid brick or stone bases and large, stately windows to ensure ample natural light. We adhere to classical principles of proportion and symmetry, creating harmonious and balanced orangery extensions that seamlessly complement both modern and historic homes. Our skilled orangery builders ensure that each traditional orangery extension is not only beautiful but also functional and durable.
For those who prefer contemporary design, we offer modern orangeries characterized by minimalist aesthetics and clean lines. We use large glazed areas to maximize natural light and create a seamless transition between your home and garden. Our modern orangery designs employ materials such as aluminium and high-performance glass, resulting in sleek, airy orangery extension spaces. These contemporary orangeries are ideal for clients who value simplicity and functionality, and our advanced building techniques ensure energy efficiency and year-round comfort.
Our Victorian orangeries bring the richness of Victorian-era details and bold shapes into your home. These designs feature ornate elements, intricate woodwork, and gothic-inspired glazing patterns, with large windows that allow plenty of light. Victorian orangeries by River.ODP perfectly complement period properties, adding elegance and historical charm. Our experienced orangery builders pay attention to every detail, creating stunning orangery extensions that are both beautiful and robust.
In our rustic style orangeries, we combine traditional elements with natural materials like wood and stone to create warm and inviting spaces. Features such as exposed wooden beams and stone flooring characterize these designs, offering a cosy, nature-inspired retreat. Rustic orangeries blend harmoniously with rural landscapes, creating intimate interiors that invite relaxation. Our construction team ensures that every rustic orangery extension is meticulously crafted for durability and comfort.
The general difference between an orangery extension, conservatory, and a traditional house extension lies in the structure of the walls, the type of roof, and how the new space connects to the existing home. The choice for you as the customer will come down to which structure will benefit the home the most and look the most aesthetically pleasing. Each has particular attributes to consider. In the table below are a few key differences to keep in mind to help you make a decision. For more complex issues or design queries, we, as your orangery builder and contractor, invite you to contact us by phone or email to discuss the construction of your chosen orangery, conservatory, or extension. No question is too small or too complicated for us, and we would be happy to help. You can also check our FAQ below.

Expanding your home is an exciting opportunity to create more living space, enhance functionality, and add value to your property. At River ODP, we offer a range of home extension solutions tailored to suit different lifestyles and budgets:
Extend your home out into your garden, perfect for creating larger kitchens, dining areas, or open-plan living spaces that embrace natural light and garden views. Often chosen for kitchen extensions, creating an open-plan kitchen/diner.
Maximise the narrow alley space alongside your home with a side return extension — ideal for transforming small, enclosed kitchens into bright, spacious, modern hubs.
Combine a rear and side extension to create an impressive L-shaped open-plan area. This is a perfect solution for families looking to redesign and dramatically increase their ground floor living space.
Expand your home upwards and outwards with a two-storey extension — adding not only larger living areas but also new bedrooms, bathrooms, or offices upstairs.
Transform your unused attic into a functional new bedroom, home office, or guest suite. Loft extensions (conversions) are a clever way to add significant value without extending the footprint of your home.
Repurpose your underused garage into a stylish and practical living area — whether it’s a cosy den, a home gym, or an extra bedroom.
The cost of a home extension depends on several key factors, including the type of extension, the size, the materials used, the complexity of structural changes, and the level of internal finishes.
Here’s a general guide:
Every project is unique. We take the time to understand your specific goals and provide tailored quotes based on your design preferences, site conditions, and the technical demands of the build.
A well-designed home extension can not only improve your daily living experience but also significantly increase your property’s market value — often by much more than the cost of the project itself.

The definition of an orangery is a type of building or room mainly consisting of a metal or wooden frame with single glazed panes that is designed to house and cultivate exotic plants, particularly citrus trees, basically a larger more extravagant greenhouse. Orangeries originated around the 17th century in Italy, and increasingly became popular throughout Europe as a way to grow citrus fruits in more colder climates.
Today, an orangery is typically a brick-based structure joined to the house, featuring large windows and a flat roof with a central glazed lantern. Modern orangeries serve as versatile extensions to the home, offering a bright and airy space that combines the insulation and solidity of traditional brick walls with the natural light and openness of a conservatory. They are often used as additional living spaces, such as dining rooms, lounges, or garden rooms, blending indoor comfort with outdoor views.
Popular options include rear extensions, side returns, wraparound extensions, and double-storey builds.
Each serves different needs – from expanding kitchens to adding bedrooms or home offices. River ODP helps select the right style based on your property and goals.
Orangeries usually cost between £2,000 and £3,500 per m².
The cost of building an orangery will depend on a number of factors, including the size and complexity of the project, the materials used, and the location. On average, an orangery can cost between £20,000 and £80,000 in the UK market mainly due to the cost per m². As experienced orangery builders and contractors, River ODP offers free advice and quotes to suit your budget without any obligation. This ensures that you receive expert guidance tailored to your needs, providing comprehensive information and estimates to help you make informed decisions about your project.
House extensions typically range from £1,500 to £3,000 per m².
Final cost depends on size, complexity, finishes, and location. A basic 20m² extension might cost from £30,000, while larger or double-storey builds can exceed £100,000. Design, structural work, permissions and internal fittings all factor in.
Not always – many projects fall under Permitted Development rules.
In most cases, an orangery and other house extensions will require planning permission. However, there are some exceptions, such as if the orangery is considered a permitted development where an existing structure is present or if it falls under certain size and height limits, situated away from any neighbouring boundaries, public footpaths, or roads. Orangeries will also need planning if there are no doors separating them from the original building.
As experienced orangery builders and contractors, a professional building company like River ODP can assist you in navigating the planning permission process, ensuring that all requirements are met for a smooth and compliant orangery construction.
Yes – even if planning permission isn’t needed, building control approval is required.
It ensures your extension meets UK standards for structure, fire safety, insulation, and drainage. River ODP manages this as part of the process.
A single-storey house extension or orangery usually takes 5–14 weeks.
More complex or double-storey extensions can take up to 6 months, plus 4–8 weeks for design, planning, and approvals. River ODP provides clear timelines from start to finish.
The length of time it takes to build an orangery will depend on factors such as the size and complexity of the project, materials used, and the weather conditions. As experienced orangery builders and contractors, a professional building company like River ODP ensures efficient project management and high-quality construction within this timeframe, adapting to specific project requirements and external conditions.
Yes – in most cases, you can stay at home during the work.
Builders section off areas to minimise disruption, though expect some noise and dust. For major structural work, short-term relocation may be more comfortable.
A simple single-storey rear extension with a flat roof is the most budget-friendly.
Costs stay lower when plumbing and electrics are close to existing systems, and by using standard materials. River ODP offers cost-effective solutions without compromising on quality.
Yes – both options can boost your property’s value by 10%–20%.
Extensions add functional square footage like kitchens or bedrooms, while orangeries add luxury, light-filled living space. A well-executed build enhances both use and appeal of your home.
Absolutely – modern builds are highly insulated and designed for year-round comfort.
River ODP uses energy-efficient glazing, insulated walls, and optional underfloor heating to ensure your space stays warm in winter and cool in summer – whether it’s an orangery or full house extension.
Orangeries and conservatories are both types of extensions that are designed to let in natural light and connect indoor and outdoor spaces. However, orangeries typically have more brick pillars and solid roofs incorporating a form of roof lantern other than conservatories which are generally constructed entirely of glass. Orangeries also tend to have more architectural features, such as columns/pelmets and cornices, than conservatories.
Both styles can be built bespoke to the homeowners’ personal choice and come in many designs. River ODP, as orangery contractors and building specialists, offers customized solutions tailored to your specific needs. They ensure each orangery is designed to enhance your home aesthetically and functionally, providing high-quality craftsmanship and attention to detail in every project.
There are many different styles of orangeries to choose from:
Traditional Orangeries feature classic brick pillars, large sash windows, and a central glass lantern, combining elegance and timeless design. Contemporary Orangeries offer sleek lines and large glass expanses for a modern aesthetic. Edwardian Orangeries are characterized by their square or rectangular shape with ornate details. Victorian Orangeries have a multi-faceted design with a bay front, offering panoramic views. Bespoke Orangeries are custom-designed to meet specific needs, incorporating elements from various styles.
French doors are most commonly used in orangeries, providing a classic and elegant look. However, bi-folding doors and sliding patio doors are also popular, especially in modern and contemporary styles, offering a sleek and seamless connection to outdoor spaces.
