15. Closing in existing veranda or patio

Enclosed veranda

A building consent is not required to close in an existing veranda or patio if the enclosed space is under 5 square metres.

What the law says

Subject to section 42A of the Building Act, Schedule 1 exempts the following from a building consent:

Building work in connection with the closing in of an existing veranda, patio, or the like so as to provide an enclosed porch, conservatory, or the like with a floor area not exceeding 5 square metres.

Guidance on the exemption

This exemption allows you to close in an existing veranda, patio or similar structure in order to convert an area into an enclosed space (eg a conservatory).

The size of this enclosed space must not exceed 5 square metres.

Examples where this exemption could apply

A building owner has an existing patio measuring 4.5 square metres in area and wishes to fully enclose it with glazing.
An owner of a bay villa decides to partially enclose an existing veranda to have a 5 square metre sunroom off the living room. Glazed window joinery is installed on three sides to create the new space.

Example where building consent is required

A building owner wants to change an existing veranda into an enclosed conservatory. The veranda measures 15 square metres in total. As the area she wishes to enclose is greater than 5 square metres, she will need to obtain a building consent.
