Building Height

The height of a building is its height above the ground level. For a flat roof construction adjoining a street, the height is defined as the vertical distance from the highest point of the roof of the building to the average level of the centre line of the adjoining street. For a sloped roof without gables the building height is from the point where the external surface of the outer wall intersects the finished surface of the sloping roof (for the gabled roof, the reference point for height on the building is the mid-point between the eves level and the ridge) to the average level of the centre line of adjoining street.
