Permitted development council agreed and now refused

A gym that size for purely personal leisure purposes seems unlikely. Are you a trainer using the gym for clients? Which would make it commercial rather than residential?

No not to be used as commercial the building in middle is made from brick and the side is like a wooden shed on each side . The garden is very big and wide . The neighbours and people on road have made huge ones and ours is 2.5metres high and over 55percent of garden including driveway is left??

I'm not sure what you want us to say.

You haven't actually told us what the planners have said.

So assuming your house isn’t made of wood, the materials used in the construction of the extension are not the same as the materials used in the construction of the house (despite you saying in post 17 that they were).

Also, what your neighbours have done is kind of irrelevant. Permitted development rights have changed over the years. Alternatively they could have obtained planning permission, or they could have extended unlawfully but are now outside the enforcement deadlines.

Also, in post 17, you state that previous extensions have all been subject to planning permission. I therefore take this to mean that the property has been extended in the past. Therefore, have your calculations on the percentage of space covered by the extension been based on the house as it was originally built? Originally built means the house as it was first built or as it stood on 1 July 1948 (if it was built before that date). As the property has, it seems, been extended in the past, some of the land around the house will have already been used.
