We've had a garden office put in today. The max height you can have without planning permission, given the location which is less than 2 metres from our boundary, is 2.5 m. We agreed with the company supplying that the dimensions would be small enough that permission wouldn't be required. The height is actually 3 inches more than the maximum (and 6 inches higher than what we asked for!). However we are desperate for the work to be finished and want to avoid a long delay of having them redo it all. My main concern relates to the planning permission - does anyone know the implications of going over the allowed max? Will it be an issue if/when we sell the house? Grateful for any advice, thanks!
