Construction Features
Some structures are better defined by their construction features, rather than by identification with a particular style or even building type. These might include barns and agricultural or industrial buildings and even bridges. Construction features sometimes are part of a vernacular tradition like notched log buildings or covered bridges, but they may also stem from an emerging technology such as poured concrete or the use of a stuctural steel frame. Thus, the design significance of such cultural resources is best understood by evaluating the method of construction, not the architect involved or the style represented. While it is possible to be very detailed in describing construction features for specific types of historic resources, for the purposes of this architectural guide, just a few of the more commonly known construction methods are included here.
