Rules of measurement
1.General(1)A distance from any point on a boundary of land shall be measured horizontally.(2)A rise, slope, or fall away shall be taken to be one unit measured vertically in a given number of those units measured horizontally.2.Thickness(1)The thickness of timber shall be taken to be the actual thickness.(2)The thickness of any plaster shall be taken to be the least thickness of the plaster.(3)The thickness of a wall or a leaf of a cavity wall shall be taken to be the actual thickness exclusive of any applied surface finish.3.Internal horizontal measurementsAll internal horizontal measurements in a room shall be measured from the inner finished surfaces of the walls or partitions excluding skirtings forming the room.4.Internal vertical measurementsFor the purpose of making internal vertical measurements—(a)a reference to a floor shall mean the upper finished surface of the floor;(b)a reference to a ceiling shall mean the underside of the finished surface of the ceiling, provided that where there is no ceiling or where a beam or rafter, other than a beam or rafter which throughout its length in the room is an integral part of one of the walls or partitions enclosing the room, projects below the ceiling, the reference shall mean the underside of the finished surface of the lowest beam or rafter; and(c)the height of a part of a chimney or flue-pipe above an appliance shall be measured vertically from the highest part of the junction of the appliance with the chimney or flue-pipe.5.Area of a roomThe area of a room shall be the total area of the floor of the room, but—(a)where there is, within a habitable room or kitchen, a stairway or part of a stairway, the area of any space occupied by any part of the stairway in any horizontal plane within that room shall be excluded from the area of the room;(b)the area of a habitable room shall be deemed to include the area of any built-in storage in that room:Provided that—(i)there is a clear space of at least two feet measured vertically between the upper finished surface of the built-in storage and the ceiling, and(ii)the area of built-in storage which may be so included does not exceed one tenth of the total area of the room;(c)the area of a kitchen shall be deemed to include the area of any built-in storage or other fixture in that room:Provided that—(i)the upper finished surface of the storage or other fixture is at a height of not more than three feet above the floor; and(ii)the area of built-in storage or other fixture which may be so included does not exceed one half of the total area of the kitchen; and(d)any part of the floor area of a room over which the height of the room is less than six feet nine inches shall be deemed not to form part of the room.6.Area of a storeyThe area of a storey shall be the area measured inside the inner finished surfaces of the enclosing walls or, where there are no enclosing walls, the outermost edges of the floor, and includes all internal and partition walls, but covered balconies or covered verandahs to any storey shall be deemed to be within the enclosing walls of that storey.7.Area of a buddingThe floor area of a building shall be the sum of the areas of the storeys comprising that building.8.Area of openings(1)The area of a window or glazed opening shall be the area of the glass therein clear of any frame, sash, mullion or glazing bar.(2)The area of any ventilation opening shall be measured inside the frame and shall exclude any sash, bar, or other obstruction to the passage of air.9.Height of a room(1)Where the ceiling over the whole or part of the area of a room is level, the height over that area shall be the vertical measurement from the floor of that area to the ceiling.(2)Where the ceiling over the whole or part of the area of a room slopes, the height over that area shall be deemed to be the vertical measurement from the floor to the highest part of the ceiling over that area, less one half the vertical measurement between the highest and lowest parts of the sloping ceiling over that area.(3)Where the floor is at more than one level, the height shall be measured from each floor level.(4)Where the height of a part of a room exceeds the minimum permissible average height by more than two feet, it shall be deemed to be the minimum permissible average height plus two feet.10.Height of a storey(1)The height of a storey other than the top storey shall be the vertical measurement from its floor to the floor next above.(2)Where the whole of the top storey is under one roof the height of the top storey shall be deemed to be the vertical measurement from its floor to the highest part of the roof less one-half the vertical measurement between the highest and lowest parts of the roof.(3)Where different parts of the top storey are under different roofs, the height of each part shall be deemed to be the vertical measurement from its floor level to the highest part of the roof over it, less one-half the vertical measurements between the highest and lowest parts of the roof over it.(4)Where parts of the floor of a storey are at different levels, the height of the storey shall be measured from each floor level.11.Height of a building(1)The height of a building, which is covered by one roof, shall be deemed to be the vertical measurement from the mean level of the ground adjoining the building to the highest part of the roof of the building less one-half the vertical measurement between the levels of the highest and lowest parts of the roof.(2)Where different parts of a building are covered by different roofs, the heights of each part of the building shall be deemed to be the vertical measurement from the mean level of the ground adjoining that part of the building to the highest part of the roof over that part of the building less one-half the vertical measurement between the highest and lowest parts of that roof.12.Average height of a roomThe average height of a room shall be the cubic content of the room divided by its floor area.13.Cubic content of a roomThe cubic content of a room shall be the sum of the volumes obtained by multiplying the heights of the various parts of the room by the floor areas under each height.14.Cubic content of a storeyThe cubic content of a storey shall be the height of each part of the storey multiplied by the area of that part.15.Cubic content of a buildingThe cubic content of a building shall be the sum of the cubic contents of its storeys.16.Buildings on columns or piersWhere the lowest floor of a building is raised above the level of the site on columns or piers, the height of the building shall be measured vertically from the underside of the finished surface of the lowest beam supporting the building, instead of from the mean level of the ground adjoining the building, but where any part of a building is raised above the level of the site on columns or piers and the vertical measurement between the upper finished surface of the pavement under that part of the building, or the ground where there is no pavement, and the underside of the finished surface of the lowest beam supporting the building exceeds five feet, that pavement, or, where there is no pavement, that ground shall be deemed to be the floor of a storey of the building.17.Stairways(1)For the purposes of this paragraph—"stairway" includes stairs and steps;"the going" means the horizontal distance between the nosings of two consecutive treads;"pitch line" means line tangential to the nosings of the treads;"the riser" means the vertical distance between the tops of two consecutive treads;"tread" means the upper surface of a step.(2)"Tread width" means the horizontal distance between the front of the tread and the front face of the riser or, if there is no riser, the back of the tread so, however, that, in the case of a stairway or part of a stairway having tapering treads, the going and the tread shall be measured at a distance of one foot six inches from that side of the stairway at which the treads are narrower.(3)The width of a stairway means the unobstructed width taking no account of any obstruction caused by handrails.(4)The height of any wall, railing, or balustrade in relation to a stairway shall be measured vertically above the pitch line.
