Lean-to Conservatories

  • Looking to add a light bright space to your home but are struggling due to height restrictions? Our lean to conservatories sound like the perfect option for you. The pitch of the conservatory can vary depending on your property; a shallow pitch is preferred for bungalows and a steep pitch is better for terraced houses.

    Lean-to conservatories can also work really well if you are wishing to convert some spare space into an extra room. A simple way to create a light, bright and airy space with an endless number of uses.

Do you need foundations for a lean to conservatory?

Lean-to conservatories require foundations. Although they use one of your property’s structural walls, foundations are still necessary if your conservatory is going to be a long-lasting and stable construction.

The depth of your foundations will depend on the type of soil your conservatory will be installed on. We’ll send a surveyor to your home before all the designs are finalised. They’ll test the soil so we know what groundwork and footings will be necessary to create a reliable, sturdy base for your conservatory.

What is a lean-to conservatory?

At AGS, a lean-to conservatory is one of the simplest conservatory designs we have on offer.

Lean-to conservatories consist of three glass walls coming out from one of the main walls of your property. They are generally smaller than a traditional conservatory and you might hear them being referred to as ‘sun rooms’.

While you can choose to have a glass roof on your lean-to conservatory (the obvious option for people looking to maximise on light), a tiled roof option is available — perfect for those who are a bit more worried about insulation.

People often get conservatories as an alternative to getting an extension. However, if you don’t even have space for most standard conservatory designs, then a smaller lean-to conservatory is another great option.

What's the difference between a lean-to and a conservatory?

Standard and lean-to conservatories have many similarities. They both let lots of light and warmth into your property and increase the amount of living space available to you and your family. 

However, they do differ in some respects. Standard conservatories are generally much larger than lean-to options and can have more ornate detailing and pitched roofs, like our Victorian or Edwardian conservatories

A gently sloping or flat roof characterises a lean-to conservatory. They tend to take up less space and don’t extend very far from your home’s exterior wall.

Visit our Exeter showroom to see the difference for yourself.

Why choose a lean-to conservatory?

If your property has restricted outdoor space, then a lean-to conservatory might be the way to go.

They don’t take up the whole garden and usually extend just a small amount away from your home. This means they can bring lots of natural light and warmth into your property without making you sacrifice valuable outdoor space.

Some homes, such as bungalows, have restricted space under the eaves, which makes installing a standard conservatory a little more difficult. As a lean-to conservatory can vary the pitch of its roof depending on the type of property you have — a shallow one for a low bungalow roof, or a steeper pitch for a terraced house — this might be the perfect conservatory for your property.

We refuse to compromise on quality

Our windows are made from British Made, high quality MarinespecTM components, with up to 25 years anti corrosion. They are built specifically for the more exposed areas of corrosion, such as coastal environments to give you worry free performance beyond your guarantee.  We believe spending more on components is worth every penny, and sets us apart from our competitors.

We have invested millions of pounds into one of the most state of the art manufacturing facilities in the UK.  This enables us to provide you with consistently high quality products at exceptionally good prices.

Superior energy efficiency

Our ‘A’ rated energy efficient and triple glazed windows are tested by the BFRC, which will save you money on your heating bills. By law your windows and doors have to meet strict thermal performance regulations but you can be rest assured that our products exceed current requirements.

Energy saving is incredibly important and so is keeping your fuel bills down. We are continuously looking for ways to make our homes energy efficient and one way is to choose new PVCu windows and doors. Not only will they help to keep your home warmer, they will reduce your energy loss.

Don’t just take our word for it!

Our suppliers conform to strictly controlled and independently monitored Quality Management Systems such as ISO 9001, to ensure that everything is done correctly and according to best practise.

Our windows are tested independently by British Standards for security, weather tightness and strength performance. This means that periodically, we have to send them to independent test houses, in order to be tested to destruction.

These are just some of the many standards the products in our vast range conform to. Needless to say we take the quality of our products very seriously indeed.
