Many conservatories fall under permitted development which means they don’t require planning permission. There are exceptions to this though, especially if you’re looking to have a large conservatory installed. Read our guide on conservatory planning permission for more information.

What are the other options for conservatory material?

Whilst uPVC is the UK’s favourite because it’s cheap to manufacture and has a number of qualities, there are also options available including aluminium and hardwood. Both are popular for various reasons.Aluminium, as a metal, is the strongest and most durable material available for conservatories. On top of this it won’t rust, warp or crack. Hardwood offers a more traditional appeal and whilst it requires high maintenance levels, is perfect for conservation areas and listed buildings.

do i need planning permission for a lean to conservatory?

Adding a lean to conservatory to your home or property comes with a whole lot of benefits. It provides you with the much needed additional living space within your property, add value to your home and creates a link between your home and garden. As advantageous as it is, one of the major concerns several homeowners have is whether or not is requires a planning permission. This is a crucial question that must be answered before you make financial commitment to the project. If you don’t know what you’re doing the entire process can be very tedious and you definitely do not want to go through the stress of completing your remarkable new conservatory, only to be instructed to have it removed again. In this post, we’re going to consider if obtaining a planning permission is required before adding a lean to conservatory to your property.

 

Generally, adding a lean to conservatory to a property is considered to be a “Permitted Development, which implies that you won’t have to apply for a planning permission to complete the project without any risk of interruption from the appropriate authorities. However, there certain circumstance that’ll require a planning permission. These circumstances include:

  • If the conservatory covers more than 50 percent of the land around the main house.
  • If the conservatory will be placed on the side of the house that faces the road.
  • If the conservatory will be higher than the highest point of the main building’s roof.
  • If the main building is lower than the height of the eaves and ridge.
  • If the conservatory will be constructed to the side of the house and more than a single storey or it goes higher than 4 metres.
  • If the conservatory will be wider than the width of the main building, if it’s to be built beside it.
  • If the conservatory will be constructed at the rear and higher than 4 metres.
do you need foundations for a lean to conservatory?

The short and simple answer to this question is yes, just like other new extensions, you must have a foundation done for your lean to conservatory. In order to transfer the building’s weight to the floor safely, there’s a need to construct a foundation. Without it, the structural integrity of the extension would be heavily compromised. What’s more? While there’s no minimum depth requirement for a lean to conservatory, there are multiple factors that can affect the depth as well as type of the foundation. Let’s take a look!

 

  • The nearby trees. What trees do is to absorb water from the soil which can affect the foundation significantly. When water is absorbed from the soil, the soil shrinks which affects the foundation’s strength. The size as well as type of the tree will determine the extent of the water absorption from the ground.
  • The soil’s suitability. The weight that each soil can withstand varies and even more so, when environmental factors have more effect on certain types of soils than others. For instance, chalk is able to drain water away relatively easily which means that nearby trees will only have a little effect on its quality. Clay, on the other hand, shrinks when drying and also retains a lot of water. This means that nearby trees will have huge impact on clay soil which will compromise the structural integrity of the lean to conservatory. Therefore, since changes to clay mostly occur to about 0.75m depth, foundations on the soil should be constructed deeper to compensate.
  • Undisturbed ground. Before the foundations are laid, there’s a need to identify grounds that hasn’t been built on and this usually takes a depth of about 1m (this figure may vary especially in regions where drains have been laid).
