What does lean-to conservatory mean?

A lean-to conservatory is a simple and cost-effective extension style that adds extra space to a home. Unlike larger extensions with double hipped roofs, a lean-to conservatory has a flatter, more slanted roof that rests at an angle between the roofline and the wall of the house.

This type of conservatory is typically square or rectangular in shape with a flat roof that slopes downwards, giving the impression that it leans against the house wall – hence the name “lean-to”.

In the past, conservatories had to have a certain percentage of transparent roofing to be exempt from planning permission. However, recent changes in building regulations suggest that you may not need planning permission for a solid conservatory roof, regardless of the conservatory style you choose.

A lean-to conservatory, being smaller in size, usually does not require planning permission. However, if you plan to construct a gable-ended conservatory with a taller and steeper roof, you must verify that your plans adhere to building regulations.

Although planning permission is usually not required, if you want to replace a glazed roof with a solid roof, you will likely require approval from your local Building Control department.

This is because solid or tiled roofs are heavier than glazing, and you need to ensure that your lean-to conservatory can withstand the additional weight.

When constructing a lean-to conservatory with a solid roof, there are specific building regulations that you must consider. For example, your conservatory should be at ground level, less than 30 square meters, and must have a glazed external door connecting to your house.

If you are concerned about planning permission and your lean-to conservatory having a solid roof, several factors must be taken into account.

For instance, has your property undergone previous extensions, is it located in a conservation area or natural beauty spot, is your conservatory visible from the road or public right of way, or is your property listed?

If you answered yes to any of these questions, it is advisable to check with your local planning authority. This does not necessarily imply that you require planning permission, but it is better to be cautious.
