I understand that the area of glass of an extension can be no more than 25% of the new floor area, however you can offset the area off window removed from the original building by the creation of the extension.
Our extension (internally)will be 28.14 sqm
the proposed amount of glazing is 12.9sqm
The amount of glazing removed from old house is 7.4sqm
Hence the additional glazing is 12.9-7.4 = 5.5sqm
This as a percentage is 19% of the new floor are so i am ok. Is this right
