Lean-To Conservatories in Littlehampton & West Sussex

Is your external vertical space too limited for a traditional conservatory? If so, then consider our lean-to conservatories. Featuring clean and simple lines, our lean-to conservatories will be able to provide you with all the benefits of traditional conservatories, such as additional floor space, aesthetic appeal, and a potential increase in the value of your property in Littlehampton, West Sussex, or the nearby area.

Adjustable Lean-To Conservatories

Get Your Designs

Lean-to conservatories are different from other types of conservatories due to the adjustable nature of their roofs. Available in a wide variety of sizes, the roofs of lean-to conservatories can be adjusted to meet different pitch requirements. Because of this, our lean-to conservatories are an excellent choice if your Littlehampton or West Sussex property struggles with the space for a traditional conservatory.

Maximum Space & Minimal Cost

Lean-to conservatories often feature simple lines that provide a clean and fuss-free appearance. Because of this, not only are lean-to conservatories typically more cost-effective, but they also provide a maximum amount of floor space for your Littlehampton or West Sussex property.

Furthermore, lean-to conservatories are also an incredible option amongst Littlehampton and West Sussex homeowners due to them being the ideal solution for properties that either have restricted space under the eaves or have an area that is too awkward to accommodate a conventional conservatory.

Further Customisation

We offer numerous customisation options for your lean-to conservatory. We can provide cornices that are curved or one-, two-, or three-tiered that are available in four standard colours and any RAL colour. Our super-insulated columns can also be added to your bespoke conservatory in different colours, panelling, and sizes for more warmth.

Our conservatory roofs can be designed with larger spans and door openings and come with different glazing options, including shaped, side-shaped, and full-length panels or a combination of all three. We also offer performance glazing with a 1.0 W/m²K U-value and high or low light transmission and solar rejection depending on how much sun your bespoke conservatory gets.

Structural Integrity

Our conservatory roofs are BBA-approved and come with a 25-year life expectancy certificate. They have been wind-tested at speeds of up to 130mph and fire-tested by Warringtonfire. Our roofs are also capable of withstanding up to 4m of unsupported bifold or sliding doors.

Internal Pelmet

Our conservatory roofs consist of a vaulted ceiling and have an internal pelmet around the perimeter. This provides a space for you to install lights or speakers in a living space that is usually difficult to light.

Energy Efficient

Our decorative super-insulated columns provide high levels of comfort and have a U-value of only 0.15 W/m²K. Our slimline ridges are 30% slimmer than traditional ridges and come with high-performance thermal breaks to prevent cold spots and condensation.


Exova Warringtonfire tests our conservatory roofs to ensure compliance with fire safety. Our conservatory roofs also fully comply with the latest Building Regulations and have been pre-approved by Assent and JHAI.

Frequently Asked Questions

What is a lean-to conservatory?

A lean-to conservatory has three glazed walls that extend out from one of the main walls of your Littlehampton or West Sussex home. Lean-to conservatories are a popular option because of the maximum floor space they provide. Because of this, lean-to conservatories are also ideal for homeowners who are looking for extra floor space.

Why choose a lean-to conservatory?

There are various benefits to choosing a lean-to conservatory. Firstly, if your outdoor space is limited, the lean-to conservatory will allow you to create extra space without compromising on warmth and light. 

Secondly, if you own a bungalow or a property with limited space beneath the eaves, a lean-to conservatory will be able to fit due to its adjustable roof pitch. On the other hand, it will be very difficult for a standard conservatory to fit in this space.

Additionally, the simple appearance of the lean-to style makes it an ideal addition for homeowners who value sleek and minimal designs.

How much are lean-to conservatories?

It is difficult to provide a price for your lean-to conservatories as the material you choose, estimated fitting time, and other factors contribute to the overall costs. The best way to get a price is to call us at 01903 723362.
