Clive Edgehill's slight, but rather overbearing, letter regarding the roof oversail of my little house (AJ 28.10.04) is self-righteously concerned about a situation that probably will never happen.
The existing Victorian house is a spacious double-frontage four-bedroom dwelling not easily convertible into flats. There are no roof extensions locally on this type of building (terrace with valley roof and front parapet wall) and the planners would take an awful lot of persuading to allow one to happen.
However, should any future occupant want to go to the considerable expense of extending upwards and gain consent to do so, they could, of course, exercise their air rights. Any modification of the oversail could be done easily and would be covered by a party-wall agreement in the usual way. Far from being an 'indignity' or 'comeuppance', it could pose an interesting design challenge to resolve the two elements.
Relax Clive, there are more important things to worry about.
