On a lighthouse site there may be a variety of different structures, including the main light tower. In many cases, there has been a lightkeeper's house associated with the site and in some cases also other support buildings, a fog alarm building or an oil shed in some cases.
We have been drawing a distinction between things that are buildings—so sort of four walls and a roof—and things that are structures, which would include things like wharves or helipads or walkways, which would not qualify as buildings but which have been the point of some of the discussion related to the bill.
So our sense is that some of the buildings may be in fact meaningfully associated with the heritage value of the light tower, something like the lightkeeper's house, which was built at the same time and was integral to the functioning of the light station, whereas these ancillary structures may in fact support the functioning of the station but in no cases have they been found to have heritage value.
