What are the permits and building regulations for a loft conversion?

As with any significant home alterations or new building work, all loft conversions require building regulations approval before a loft conversion project. You need planning permission for conversion in a conservation area or listed building. You also need permission if you’re altering the roof shape or height. Additions of 40m³ for a terraced home and 50m³ for other homes fall under permitted development.
