Planning for Conservatories

The biggest question that you’ll be asking yourself will be do I need planning permission for my DIY conservatory?

The vast majority of the time, you will not need to obtain planning permission in order to build a DIY conservatory. This is because they are considered to be ‘permitted development’. 

However, this is only the case when the following conservatory planning permission conditions are met:

• Conservatories do not extend beyond the side wall of the house.
• Conservatories must not take up more than 50% of the land area around the ‘original house’.(The original house is the state of the house when it was first built, or exactly how it stood on July 1st 1948).
• Conservatories cannot be higher than the original roof of the home.
• No conservatory can be forward of the principal elevation or side elevation fronting a highway.
• A single-storey rear extension cannot exceed 4 metres in height.
• A single-storey rear extension cannot exceed 3 metres in depth, for an attached house, and 3 metres in depth for a detached house.
• The maximum depth of a rear extension (more than one storey) is 3 metres – including the ground floor. Side extensions must be single storey – and cannot exceed 4 metres in height, or a width of more than half of the ‘original house’.
• The eaves and ridge height of a conservatory cannot be higher than the house.
• The eaves within 2 metres of the boundary cannot exceed 3 metres.
• An extension cannot include balconies, raised platforms or verandas.
• A roof pitch on conservatories higher than one storey must match exiting house.

Most of the time, meeting these requirements will be simple.
