Under normal circumstances, and if built further than 5m from the house, no planning permission is required in the UK for any of our domes. If closer than 5m to the house it is classed as an extension and standard allowances apply. None of the domes require building regulations if they are situated over a meter away from any boundaries. If you live in a listed building or an area of outstanding natural beauty and a conservation area, you will need to check with your local planning office.
