What is a Lean-to Conservatory?

Lean-to conservatories are considered the simplest conservatory design, reminiscent of a Mediterranean sunroom and generally an ideal choice for extra space. The modern lean-to conservatory roof slopes away from the home, rather than being a lantern or double hipped styled roof and often at a lower pitch. Lean-to conservatories include large areas of glazing, often supported by a dwarf wall with a square or rectangular floor plan. Bungalows, properties where space under the eaves is limited or for homeowners that prefer a simple look, a lean-to conservatory is the ideal choice. Our beautiful lean-to conservatories, also known as Cheltenham are our most popular style, built from uPVC to create a space that enhances your home and garden.

Why choose a lean-to conservatory?

Slanted roof system

Lean-to conservatories are the simplest extension style offering an incredibly affordable way to add space to your home. Rather than a larger, double hipped roof, lean-to conservatories come with a flatter, more slanted roof that sits at an angle between the roofline and the wall of your home. The sloped roof is often at a lower pitch, although this can vary making them a very versatile option. Despite a more modest design, a lean-to conservatory will still deliver a superb performance.

A highly insulated, warm room

A lean-to conservatory creates a spacious and sun-filled extension to your home. Our lean-to conservatories offer fantastic thermal performance so they can be used all year round, without the worry of high heating bills. A high-performance roof system helps to prevent the escape of natural warmth, allowing you to feel fully disconnected from the cold outdoors.

Easy to install & maintain

Perfect for properties where space is small such as bungalows or terraced homes, as the low pitch roof can be accommodated easier. With a rectangular shape and a large area of glazing, a lean-to conservatory will allow you to make the most of your space for a spacious, light-filled extension to your home. Our lean-to conservatories are constructed from uPVC which is incredibly durable and requires low maintenance.

What roof can I have on a lean-to conservatory?

At Everest, we give you the choice of 3 distinctive roof types for your new lean-to conservatory.

Everest glass conservatory roof

Glass conservatory roof

A very common option when designing a new conservatory is to choose a glass roof. Glass conservatory roofs consist of large glass panels that provide copious amounts of natural light into your home, even on an overcast day, compared to polycarbonate or tiled roofs. Everest conservatory glass roofs have superior solar control eco clean glass, which will help to keep your conservatory cooler in the summer and make it easier to keep clean.

Livin'roof combines solid and glazed roofing seamlessly for a stylish look and thermally efficient room. The Livinroof roofing system is constructed from insulated composite external panels and high-performance PU board insulation. These are strong and robust, and totally thermally efficient. Glazed panels can be inserted to replace almost any of the roofing panels to maximise light and produce a contemporary feel that is not easily achievable with other types of roofing systems.

Our tiled roof extensions are specially engineered to maximise the amount of glass, but still have the strength and stability built in to support a tiled roof. The sturdy insulated roof panels give superior thermal performance and comply with all current building regulations. With the added option of full height glass panels in the roof, you can let in natural light where required, creating the best of all possible worlds.

Lean-to conservatory FAQs

Choosing a new conservatory can be a daunting task, so to help you here are some popular FAQs which you might find useful.

  • +
    Why choose a Lean-to Conservatory?
    Lean-to conservatories are the most suitable and cost-effective option for both modern and traditional homes, in particular for properties that are modestly sized or where space under the eaves is limited. They are also a great option for single storey bungalows, as they will remain compliant with building regulations. Often lean-to conservatories will have a square or rectangular floor plan, making them easy to decorate and furnish so you can maximise your new living area whether it’s for relaxing or for working from home.
  • +
    Can lean-to conservatories be fitted to bungalows?
    Yes, lean-to conservatories can be installed onto a bungalow, in fact we often recommend this style for bungalows and homes with low roofs. It tends to be the most popular and cost-effective conservatory style due to its simple design and with its variety of customisation options it will easily suit any type of bungalow.
  • +
    Do lean-to conservatories require planning permission?
    You can add a lean-to conservatory to your home without planning permission, as long as it is within the boundaries of your property and doesn’t cover more than half of the total area. The conservatory can’t be higher than the eaves of your existing house and can only be a maximum of 4m high. In most cases, you will not need planning permission but to keep your new conservatory process as stress-free as possible, Everest will take care of all the necessary planning permission to ensure your new construction conforms to all UK building standards and requirements.
