What is a Lean-to conservatory?

A Lean-to conservatory has a flat, slanted roof that sits at an angle against the wall of your home. Its simple structure makes it a very affordable style of conservatory. What’s more, Lean-to conservatories can be large or small, depending on how much space you have.

Do I need planning permission for a Lean-to conservatory?

You don’t need planning permission for your Lean-to conservatory as long as it meets specific requirements. If your extension exceeds these, you’ll likely need approval before construction. Find out more about planning permission for conservatories.

Can Lean-to conservatories be fitted to bungalows?

Yes, Lean-to conservatories can be added to bungalows. In fact, due to their sloped roofs, Lean-to designs are a great choice for bungalows because their roofline is lower than other conservatory styles. Read more about conservatories for bungalows.

Do Lean-to conservatories need foundations?

Yes, your Lean-to conservatory will need foundations to ensure it’s safe and stable. We offer a high-quality steel ConservaBase system that you can include in your conservatory design, which makes assembling your new extension from the ground up easier than you might think. Find out more about installing our conservatory bases.
