Rear extension permitted development

I’m hoping someone can help me with a query I have. I applied for planning permission for a 2 storey rear extension projecting 6 meters from the back of the property and being half width of the house. This has been refused.

My architect has suggested a way round it. He suggests doing a permitted development single storey of 6 meters and also do a permitted development of a double storey of 3 meters at the same time. Is that allowed ? I can only seem to find information that suggests you can only go 3 meters ground floor and 1st floor ?

He says once that is built., You can then apply for planning to extend the 1st floor extension by another 3 meters . Obviously a long winded way of getting what you want. Is this possible or realistic ?

I hope that makes sense.

This sounds familiar. Have you asked the same question on another forum?

If the resulting extensions will be two storey, you’re restricted to an overall depth of 3m. You cannot have the ground floor projecting further out than the first floor under PD. There are also rules relating to eaves height when buildings within 2m of a boundary.

Even if you built a ground floor rear extension at 6m (which would have to be via Prior Approval), the first floor element would require formal and Full Planning. If the LPA have already refused permission for a two storey rear extension, I don’t know why they would then approve an application for a first floor rear extension. The added bulk will still be assessed and may be deemed as unacceptable.
