Lean-to Conservatory Cost (2020)


What Does it Cost to Build a Lean-to Conservatory?

Modern house conservatory

Have you always dreamt of having a conservatory built onto your home, but is the cost holding you back? Well, have you considered a lean-to conservatory? This type of conservatory is perfect if you’re on a budget but still want to gain extra space and extend your home.

A lean to conservatory can be used to increase the space of your home, create additional storage space for large items, and to give you a place to relax while looking at your garden.

The reason you might want a lean to conservatory may be different from the above. But the great thing about lean to conservatories is that you can use them for anything that you like and will cost less than having a new extension built onto your home.

One of the best features of a lean to conservatory is that it allows maximum natural light into your conservatory compared to some of the other styles of conservatories that have a different type of roof. The lean-to conservatories have a sloping roof, which is usually made from either glass or polycarbonate, and these materials allow light in from every angle, including the sides.

Lean to conservatory prices will alter depending on the type of specification you select. You can choose from many different materials and even include dwarf walls, which will add to the overall conservatory cost. Although a lean-to conservatory cost is lower than other conservatories, such as the Victorian, Edwardian, and Contemporary, these new conservatories cost are a lot more – especially Contemporary conservatories.

Conservatory prices can vary widely. For all types of conservatories, the cost ranges between around £5,000 and up to and exceeding £20,500. The lean-to conservatory cost dips towards the lower end of the price range. You can pay between £5,000 and £10,000, based on the materials you choose for your new conservatory.

Lean-to Conservatory Features

Lean-to conservatories have design features that identify them from other conservatories, such as a sloping roof that starts on the wall of your home and slopes down meeting the side walls. This also helps with drainage for the conservatory roof.

A lean to conservatory is rectangular and can also be square, depending on the size of conservatory you require.

The structure of lean to conservatories is always with straight lines. There are no curved features that can be found on conservatories like the Victorian.

Due to lean-to conservatories being relatively small in design, and their simple structures, you don’t generally need planning permission to construct one. However, you should always check to make sure.

Factors That Will Affect the Price of a Lean-to Conservatory

A wide range of factors will have an impact on the overall cost of your new lean to conservatory. You should be aware that specific features, such as a dwarf wall, can add a significant price increase, and you could save money by omitting this and opting for a fully glazed wall instead.

The Type of Wall You Select for Your Lean-to Conservatory

Glass wall conservatory

Lean conservatories can be constructed with two different types of walls. You can choose between a dwarf wall or a full height glass wall. Depending on which one you want, lean to conservatory prices will increase. That’s if you select the dwarf wall to be built instead of the full height glass wall.

If you want to keep your lean to conservatory prices at the lower end, then it’s advisable to go for the full height glass walls. This means that your lean to conservatory will have double glazed panes of glass. The glass will go from the floor to the roof of the conservatory. There are other glazing options if you prefer, but these will also affect costs.

This fully glazed look can work well with a home that requires a lot of natural light. It will make your space seem bigger than it is, which is a bonus. Another plus to having a glazed wall is that you can achieve a slightly modern or contemporary look of a conservatory but on a budget.

Many of the modern conservatories have this feature of floor to ceiling glass within their design. Unlike lean-to conservatories, the contemporary conservatories are at the higher end of the scale – they cost up to and beyond twice the price of a lean-to conservatory, creating a luxury look but with less cost.

The other option is to have a dwarf wall built for your lean-to conservatory. Dwarf walls will cost more as brickwork can be costly and will also require more materials to be used, such as the bricks themselves, and the concrete.

The ground will need to be excavated. Not only are more materials needed to construct dwarf walls, but you also need to consider the labour costs, too. It will take longer to build as the ground will need to be prepared thoroughly.

The initial digging process could take a while, depending on if they encounter any unforeseen issues while the ground is dug-out. The dwarf wall will also need time to dry and set before any framework can be placed on top to ensure it creates a sturdy and robust base structure. Otherwise, in time, issues will start to appear on the conservatory.

There are a few aspects you should consider before deciding which wall you would like to have on your lean to conservatory. If your garden is over-looked by many other houses in your area, then a full glass pane may not be the best answer. Although cheaper, it won’t provide you with any privacy as the whole space is visible.

You can purchase blinds that you can fit internally and close them for privacy. But you won’t want these closed during the daytime, and they will prevent natural light from entering your conservatory. The reason for many people to have a conservatory is not just for added space, but to allow them to look out onto their gardens.

Another aspect to consider is whether you’re going to have a heavy framework installed. Even though it will cost more, a dwarf wall is recommended as it can effectively support a heavier framework, such as timber. It will also offer more privacy than a glazed wall as it will be around a meter high and will prevent your new home space from being completely visible.

The only area that will have more glazing is where the French doors will be placed, so you can strategically place these to the side of your conservatory instead of the front to prevent opposite neighbours from seeing directly through.

If you do have a dwarf wall built, you might need planning permission, depending on where you’re building conservatory. Although, it should fall within the permitted regulations but double-check.

The Type of Framework Used for Your Lean-to Conservatory

Conservatory prices will be largely affected based on the type of framework you choose. There is a choice of three materials for your framework, which includes uPVC, aluminium, and timber.

Each of these materials will have an impact on the overall look of your lean to conservatory. Plus, if you live in a particular area, such as a conservation area, or a listed building, you may need to keep in with the natural feel.

This may be non-negotiable, and you might need to have a timber frame built on to your conservatory. It’s best to check if planning permission is required for your property if you do fall in the above categories.

The most favoured choice for many people is the uPVC framework. It’s a durable material, and it’s easy to maintain. If it becomes dirty on the outside, you can simply wipe it clean. Also, uPVC is featured on the framework of many windows and doors of each home within the country. You won’t need to worry if this style will blend in with the rest of your home.

Another positive regarding uPVC framework is that now there’s a vast range of different coloured uPVC that can be used, so you don’t have to stick with a white frame if you prefer something a little bit different. Also, by choosing a coloured frame, you can again make your budget conservatory look slightly like a contemporary one as these modern custom-made conservatories generally avoid white framework.

If you opt for a coloured uPVC framework, it may cost slightly more than the original white uPVC colour. But if you don’t mind the original look, then you could save money on this feature and ideally spend it on another conservatory feature.

The most expensive framework is one made from timber. But, as mentioned before, you might not be able to get around this and need to install this more expensive frame. However, a timber frame can give your lean to conservatory a more eloquent look if you’re happy to pay a bit more for this specific design feature.

In terms of maintenance, a timber frame will be more time consuming than both of the other materials. This is because the timber needs additional care and treatment to ensure it will last a long time. It needs to be kept in reasonable condition to support the conservatory windows and roof.

If you prefer something in the middle, the aluminium framework is an ideal option for your lean to conservatory. It will last a long time, and it’s easy to maintain in the same way as the uPVC framework. Just like the uPVC framework, there is a choice of colours, which gives you your desired look. It’s very similar to uPVC in the sense that it can provide your lean to conservatory with a modern and contemporary look without the price tag.

The Type of Glazing You Select for Your Lean-to Conservatory

Conservatory Open Windows

There are several types of glass that you can install for lean to conservatories. They range in price, and you could save a considerable amount of money by choosing to have standard glass in favour of laminated glass, which is the most expensive.

Also, bear in mind that most of your conservatory sides will be glazed. This is where a large increase can be seen in the overall cost if you choose to go for high specifications on the glazing

The following options are available for the glazing of your conservatory:

  • Standard glass – double glazed
  • Low E glass
  • Self-cleaning glass
  • Decorative glass
  • Noise-reducing glass
  • Toughened glass
  • Laminated glass

Each glass type has unique features and can be beneficial for homeowners in various ways. If you live in a noisy street, you may opt to have noise-reducing glass to ensure your new space is a peaceful environment for you to relax.

If you are going for a fully glazed wall, having noise-reducing glass may be the best way to make sure that you’re not disturbed by your outside environment.

The standard glass option is double glazed, although you can select triple glazed with a slightly increased cost. Most people choose this option, and it works well with any frame type. Another factor to consider is the type of roof you’re going to install.

If you’re going for a glazed option, you will most likely choose the same glazing for the roof. So to keep costs down, double glazing would be a good option. Otherwise, you will need to install higher-priced glazing to complete the roof.

For energy efficiency, Low E glass is the best option but more costly. It will keep your lean to conservatory at an optimal temperature throughout the year. The metallic coating on the glass prevents the transfer of heat from the outside. It does the same from the inside.

Self-cleaning is a good option, especially if you’re glazing your roof and going for floor to roof glazing. It works all year round and uses water from the environment to self-clean.

It will also help to reduce noise. If you don’t need the self-cleaning element, you could choose the noise-reducing glass instead. This is specifically designed to allow less sound into your lean-to conservatory.

If you like seeing colour in your windows, you can select a decretive glass instead. You may not want to put this all around the conservatory, but you could choose specific areas to inject a bit of colour and prevent your conservatory from looking dull.

Toughened glass and laminated glass are very similar, apart from the price and one feature. Laminated is more expensive and contains a plastic film that protects you if the glass was to break. If the glass breaks, the film stops it from falling.

This is a great safety feature and you should consider it to prevent accidents, especially if you have a full-glazed wall. Plus, it’s an additional safety feature. Both toughened glass and laminated are up to four times the strength of standard glass, so it might be justifiable to choose and pay more to install this glass into your lean to conservatory.

The Type of Roof Installed onto Your Lean-to Conservatory

The lean to conservatory roof is normally made with polycarbonate or is glazed. You can get the roof tiled if you prefer this look, but it will cost more and will take longer to complete.

Polycarbonate, used to be the standard for a lean-to conservatory roof as it’s low in price, can be installed quickly and allows rain to drain off effectively. During heavy rainfall, a polycarbonate roof can be noisy as the rain lands on it, but if that doesn’t bother you, then this type of roof could save you a lot of money.

If you want to glaze your roof, you can choose from a wide range of glass types at various costs, as mentioned above. A standard glass works well for the roof. You could lower costs by selecting this type, but it’s a good idea to remain consistent with the glazing that you choose from the side, especially for the noise-reducing glass, self-cleaning, and the Low E glass.

The Size of Your Lean-to Conservatory

This will be a significant factor in your lean to conservatory price.

If you don’t require a lot of space in your new conservatory, then you could choose a small size and keep costs down. If you do need as much space as possible, you can opt for a larger size but then decrease some of the other features. Choose a standard glazing option, with a polycarbonate roof if you are tight on your budget. This will then allow you to increase the floor space of your conservatory.

This is an excellent strategy to apply to other features. For example, if you want a dwarf wall built for privacy and don’t mind the size of your conservatory as long as you have an outdoor space, you could opt for a small lean to conservatory.

One of the great features of a lean-to conservatory is that you can build it onto any sized home. If your house is only small, you can make a small conservatory, and it will keep in with the style of your house and not take away too much garden space.

The Internal Design Features of Your Lean-to Conservatory

The inside of your conservatory will need to be designed to your liking. The cost will be dependant on certain features you choose.

You will need to decide on the type of flooring that you would like. Carpet, vinyl, and laminate flooring are cheaper options, whereas tiled and real wood flooring is more expensive.

The type of blinds you have on the inside is a factor to think about, or you could do without and make a saving.

Does a Lean-to Conservatory Need Planning Permission?

The good news is that most lean to conservatories don’t need planning permission. However, you should make enquires to ensure that your lean to conservatory is compliant with regulations. If it doesn’t comply with the rules, you will need to apply for planning permission. That can sometimes cost you a fee.
