How we count

These are Lambeth's own refusals of loft conversions and dormers, decided in the last three years and listed on its register. For each one we read the decision notice and sorted its reasons by what they were about. 6 we have not read yet; they are counted as refusals and not as refusals without reasons.

A refusal usually gives more than one reason, so the shares add up to more than a hundred. Which refusals they were, where, and what each said, is in the Planning Forecast for your address, with a link to each council's own notice.
