Seamless Entrance To The Outside

This lean-to conservatory offers seamless access to the outside. In conjunction with beautiful bi-folding doors, a lean-to conservatory provides you with a stylish entrance to your garden or patio.

Lots of Choice

There are many base options which include dwarf walls, full height glass panels and uPVC panels that are at the foot of the conservatory. Dwarf walls will provide you with the most insulation as well as a greater level of privacy and security but uPVC panels are usually the cheapest option.

Simple Style

The simple lean-to style features clean, symmetrical lines making them ideal for modern homes. This understated structure is ideal for those who prefer a subtler design as the lean-to will not upstage the rest of your property.

The lean-to conservatory is very adaptable and can be tailored to suit any awkward spaces. This is why it is recommended for smaller properties that are restricted in space. The roof can be as low or as high as required.

Lean-To Conservatories

What is a lean-to conservatory?

A typical lean-to conservatory is rectangular or square in shape, with the longer sides running along the back of the house. It captures a beautiful timeless look that has led it to be affectionately referred to as a Mediterranean sunroom. With this in mind, they will prove to be a fantastic addition to both modern and traditional homes alike. It won’t matter if you’re looking to get something that is going to be more traditional or something that is going to offer a more modern appeal.

Unlike other conservatory styles, it has a flat angled roof that slopes downwards – appearing as if ‘leaning’ against the property. This makes it a highly versatile option that can be easily tailored to suit a wide range of property styles. Whether your property is large, or on the smaller side, then you won’t have to worry about missing out on the quality on offer. Simply speak to your installer of choice to see what they can offer you in regards to their lean-to offerings.

Standard lean-to conservatories have dwarf walls with double glazing on all three sides. With this in place, they are able to bring a fantastic harmony between natural light allowance and a structural feel. With this in mind, investing in a lean-to conservatory is a great way for you to light up your home without having to worry about missing out on the safety and security that accompanies a more modern build.

The lean-to conservatory roof is lower than other conservatory styles that have apex roofs. This is why they are highly adaptable and suited for any type of property, especially bungalows, terrace houses or properties with low eaves. Your installer of choice will be able to offer you a lean-to conservatory that has been based on your exact specifications. This means that you’re sure to get the ideal fit for your home.

All you’ll have to do is follow the simple, step by step process that will enable you to see your ideal lean-to conservatory come to life. Once you have this price, we’ll then put you in touch with three of your local and accredited installers to help get the ball rolling for you. This way you can enjoy industry-leading products with exceptional service.

Mediterranean Conservatory

Lean-to Conservatories are also commonly referred to as ‘Mediterranean conservatories’ or ‘sun-rooms’. This is because they are often used as greenhouses because of their ability to maximise natural light. With this in mind, they are going to help you enjoy a bright and spacious feel without having to worry about letting the elements in too. Through this, you won’t have to worry about feeling trapped in or confined to a small space.

The lean-to conservatory is also used for many other common purposes, making it practical, versatile and highly accessible. As they can achieve an impressive degree of thermal efficiency, security, durability, design, and performance, they can be used just like any other part of the house. Common and popular options include offices, gyms, dining rooms, living rooms, playrooms, games rooms, kitchens, and even bedrooms! Your installer of choice will be able to advise you on how to best use your lean-to conservatory for the space that you have.

Lean-To Conservatory Designs

There are many variants of the lean-to conservatory such as fully glazed and dwarf wall designs. The flexibility of design is what makes lean-to conservatories so popular with home-owners. Whether your home is modern, traditional, period, heritage, new build, or anywhere in between, you’ll be able to find a lean-to conservatory that is going to complement both your personal tastes and your existing architecture.

A clean, simple structure with modern features, the lean-to conservatory works out to be the most cost-effective conservatory style. They are smaller and take less time to construct thanks to their straight forward design. You’ll be able to make your home a warmer, safer, and more comfortable place to be across the course of the year without having to worry about breaking the bank to do so.

Conservatory Glazing Options

Lean-to conservatories come with a choice of full-height glass panels, raised uPVC panels or polycarbonate roofs. You can also choose from a wide range of glazing options too, especially when it comes to a glass roof. This will include self-cleaning glass, thermal glass, toughened glass, coloured glass, solar glass, and a range of bespoke decorative options. Speak to your installer of choice to see what they can offer you in regards to their glazing options.

Polycarbonate roofing is the most affordable option however, it isn’t the best choice in terms of insulation and energy efficiency. You are also more likely to hear the downfall of rain against a polycarbonate roof, making it the noisiest option for your lean-to conservatory. However, polycarbonate is cheaper and much easier to maintain when compared to glass. So, it’s up to you as to whether you want to go for this option or not.

Lean-To Conservatory Roof Options

Solid Lean-To Conservatory Roof

A solid lean-to conservatory roof is a great way to bring a modern feel to your conservatory, comprising a chic grey panelled design that offers a contemporary look. They also feature a plastered interior that enables them to create a completely seamless ‘room-like’ feel. This interior also serves as a great place to house lighting and speaker options too. This is a fantastic way for you to create the right ambience in your property.

The solid roof design is also the most versatile roof design on the current market, which enables you to choose where and how you want the glazing to be placed. Whether you want to flood your home with natural light or you want something that is going to bring more of a focal point, you’ll be able to choose a wide range of options. Simply speak to your installer of choice to see what they can offer you when it comes to your glazing options.

Glass Lean-To Conservatory Roof

Conservatory glass can now be self-cleaning and is available in a wide range of styles. It may cost a bit more, but the benefits of a glazed lean-to conservatory usually out-do those of polycarbonate. This option is the ideal choice for bringing a bright and spacious feel to your home without worrying about letting the elements in too. This is because they are fitted with high-performance weatherseals that work to keep draughts and water ingress out of your home. This is important for ensuring comfort and longevity are maintained.

Glass also lets in more light so if you picture a bright and glowing atmosphere then glass is the best option to go for. You can also opt for solar glass to ensure the furniture in your home doesn’t fade when it gets exposed to the UV. These roofs are also fitted with an insulated internal pelmet that works to increase the overall heat retention of your conservatory too. Alongside this, they can house lighting and speaker options to help you capture the right ambience for your property.

Tiled Lean-To Conservatory Roof

A tiled lean-to conservatory roof will enable you to capture all the best of traditional charm without having to sacrifice all the best of modern innovations. They are manufactured using tiles that are inherently lightweight, all while maintaining the classic look of the original design. They are also available in a wide range of colours to help you capture a tiled look that is going to help you perfectly complement the look of your home.

The inside of these roofs is plastered, with the option of integrated glazing panels at your disposal. The plastered interior of this roof means that you’ll be able to choose from a host of lighting and speaker options too, which is perfect for enabling you to determine how your tiled lean-to conservatory feels. Also, as the tiles are modern they are inherently lightweight and low maintenance which makes them the perfect modern alternative.


The ventilation of your conservatory is very important.  When specifying your lean-to conservatory you will have a choice of either manual or electronically operated roof vents. Both of these will be highly effective when it comes to ensuring your lean-to conservatory is ventilated as it should be. With this in mind, this is important for ensuring you don’t have to worry about a mould or damp build-up.

You will need to consider which is best for your lifestyle and what you will actually use your conservatory for. If your lean-to conservatory is simply a spare room to wash laundry, then a manual roof vent will be sufficient enough. If you are planning on using your lean-to conservatory as a living area and are likely to be opening your vents more regularly, then an electronic roof vent will be much handier.

Benefits of Lean-To Conservatories

As the modern lean-to conservatory has been refined over the years, you can rest assured that you’ll be bringing a worthwhile investment to your home that is going to continue to bring lasting value and quality long after it has been installed. Alongside this, they also bypass any of the traditional problems that usually accompany outdated conservatories. For example, you won’t have to worry about your conservatory getting too hot in the summer or too cold in the winter. We’ll run through the other benefits below:

Thermally Efficient

The thermal efficiency of your lean-to conservatory is an important factor when it comes down to ensuring your lean-to conservatory remains usable across the course of the year. To ensure this is made possible, a modern lantern-roof comprises a range of features that enables the warmth from your central heating to stay in your property for a longer period of time. This includes thermally efficient windows and doors, a thermally insulated pelmet, thermal glazing, and super-insulated columns to keep the winter winds at bay.

Not only does this mean that you won’t have to worry about becoming uncomfortable during those colder winter months, but it could also save you money in the long run too. This is because the heightened degree of heat retention will enable you to lower your reliance on your central heating to keep your conservatory at the optimum temperature. In turn, this means that you could be enjoying a lower annual heating bill as well. Also, as you rely less frequently on your energy use you could find that your carbon footprint is reduced too!


It used to be that the conservatory was a weak spot in your home, but the modern age ensures that this is no longer the case. This is because a modern lean-to conservatory comprises a range of high-performance security features that will work to keep any would-be intruders out of your home. This includes premium-grade materials, high-security locking systems, inherently secure designs, and a professional installation from your nearest accredited installer.

For your peace of mind, all of the entrance points in modern lean-to conservatories are fitted with high performance, multipoint locking systems that engage at multiple points of the frame. This means that security is kept consistent across the whole frame, avoiding any weak spots that could be potentially used as a point of leverage. They are also integrated into the frame to ensure they can’t be used as a way to compromise the frame of the window and door.

Low Maintenance

Due to the inherent qualities of uPVC, aluminium, and modern timber, you won’t have to worry about any headaches that come with maintenance setbacks. This means that you won’t have to worry about the frames warping, twisting, bowing, cracking, or discolouring. You can rest assured that a modern lean-to conservatory is going to stand the test of time when it comes to being exposed to the elements or used over a long period of time. In turn, this means that they are sure to be a worthwhile investment for your money.

Also, as they won’t feature any of the classic maintenance problems you won’t have to worry about any cutting, sanding, painting, or varnishing to ensure your lean-to conservatory looks and performs as it should. This is important as a rotting frame is going to pose both security and structural problems, which is going to leave your home vulnerable to security and safety risks. Also, not to mention the negative effect that it’s going to have on the aesthetic of your conservatory. All you will have to do is give the windows and doors a quick wipe down with a damp cloth to keep them looking and performing as they should be


Nothing says a personal touch like the freedom to choose the look and feel of your lean-to conservatory. With this in mind, you’ll be able to opt for your choice of windows, doors, colours, roof, accessories, and a host of interior décor options to help you bring your ideal lean-to conservatory to life. Whether you’re looking for a design that is going to stand out, or something that is going to blend into the architecture of your current home, your installer of choice will be able to offer you something ideal to suit.

Whether you want a conservatory that is opened up by a bi-fold door, or you want to capture the best of European charm through a French door design, then all you’ll have to do is let your installer of choice know. If you’re after something a bit more traditional then you can opt for woodgrain foils that will enable you to capture all the beauty of a timber look without having to worry about any of the maintenance problems that usually accompany the material. This way, you’ll be able to enjoy the best in modern function with traditional appearance.

Professionally Installed

For your complete peace of mind, we’ll only put you in touch with lean-to conservatory installers that are accredited and offer the highest standards of quality. This means that you’ll be able to enjoy the highest standard of professionalism, reliability, efficiency, promptness, and complete respect for your home and for your time.
