Conservatories and Rear ExtensionsDo I Need Building Regulations?

For a Conservatory, you will not require Building Regulations when

  • It is less than 30 square metres in floor area and is built at ground level
  • at least half of the new wall and three quarters of the roof are either glazed or translucent material
  • the conservatory is separated by external quality door(s)
  • glazing and fixed electrical installations comply with the applicable building regulation requirements

When planning where to locate a conservatory, it is advised not to construct conservatories where they will restrict access to windows serving rooms in roof or loft conversions, particularly if those windows are intended to help escape or rescue in the event of a fire.

What is important to remember is that if you intend to create a structural opening between the conservatory and the existing house, you will require building regulation approval for the opening, even if the conservatory is considered an exempt structure.

For a single storey rear extension, you would require Building Regulations.
