Scaffolding would usually fall outside the definition of development (Section 55 of the Town and Country Planning Act 1990), since it isn't permanent and can very quickly be moved/dismantled.
4 years however seems an exceptionally long time and I guess an argument could be made that the scaffolding has become permanent and might not be capable of being easily moved. An alternative approach might be a potential notice under Section 215 of the Act which relates to untidy/unsightly land.
Have you spoken to the landlord to express your concerns ?. |
