What is a lean-to-conservatory?

A lean-to conservatory is typically rectangular or square and has a gently sloping roof and is named as such because it appears to lean against the property. Although it’s not uncommon to see lean-to conservatories with tiled or solid roofs, they generally have glazed roofs and comprise three walls whilst using an existing exterior wall as the fourth. Lean-to-conservatories provide many benefits for those with less outdoor space and as they let in tons of natural light, are also known as sunrooms that can be enjoyed throughout the year.
