Covenants and building lines

[wowzy2001]

Thee are covenants attached to the deeds on our estate that say that nobody can store a caravan, boat etc. on their property unless they are behind the building line. Our new neighbours have purchased a caravan and now it has been on their drive for three weeks. i had already said that it was against covenants attached to the deeds and she ensured me it wouldn't stay there and it has. The trouble is she said that the building line is the pin curbs at the end of the drive and I think it is the furthest forward part of a house on the row. who is right? Also who will enforce the removal? The Council? My house is up for sale and this caravan may impeed a sale. Please advise me.
