I have a link detached property on an estate of similar with a restrictive covenant (NO GARAGE TO BE USED FOR ANYTHING EXCEPT FOR STORAGE OF DOMESTIC OR HOLTICULTURAL EQUIPMNT AND PARKING YOUR CAR)

My neighbour wan't to convert their's into a bedroom with window to the front,therefore turning my home into a semi detached property.

Are they able to do this?

Thank you

Could you give more detail why their conversion whould change the status of your property. Covenants are funny things, nearly imposible to change, hard to understand. I think your covenant was written to prevent someone from running a business out of their garage but that may not prevent them from converting it to a home. There must be many other covenants and building regulation you need to read.
