I view it as a placeholder. There are some house there but I don't know where the individual boundaries are and I can only give you a range of addresses, if that. Then, after having replaced a terrace mapped by somebody else with individual houses, I came to the conclusion that I wouldn't bother mapping things as terraces - too much effort for too little gain if I intended to replace them at a future date. I see no point in wrapping individually-mapped houses in a terrace. If they're conjoined then it's already obvious that they're part of a terrace. -- Paul
