Scope of Listed Building Controls
Listed building controls apply to all works including repairs that affect a building's special interest. The term "building" is defined broadly to include walls, bridges, and other structures, and protection extends to interiors and most buildings within the curtilage of the listed structure. All listed buildings receive equal protection regardless of their grade (A, B+, or B).
Listed building controls apply to all works, including repairs, that affect a building's special interest, whether or not the particular feature concerned is specifically mentioned in the list description. The term "building" is defined broadly and can include, for example, walls and bridges as well as structures falling in the more usual understanding of the term. Protection also extends to the interior of listed buildings and to most buildings within the curtilage of the listed structure. Buildings included in the statutory list are divided into three grades A, B+ and B. The Department would however emphasise that the statutory controls apply equally to all listed buildings, irrespective of grade.
