The original purpose of columns is to provide support for the building itself. A well-spaced column added strength to the structure. For instance; a column added support to an upstairs floor that sagged, or to a ceiling that held large amounts of snow during the winter. With modern architectural advances, wooden columns are no longer needed for foundational support, although they are still used in older homes.
Many home owners choose to add an outdoor deck to their houses if they have the space. They often choose to put in wooden columns to add a more rustic and outdoorsy feel to the area. The choice of wood ranges, depending on the style of house, but popular choices are redwood, cedar or treated lumber.
Another great use of wood columns is for decoration inside and outside the house. The use of nude woods without any staining or finishing is common when creating a more natural look. Other options include painting the columns a color that matches the ambiance of the room, and adding trim to the tops and bottoms of the columns.
Architects and interior designers use wooden columns to add ambiance to their designs. Columns can adorn the entrance to a house, or decorate doorways inside the house. Moldings that wrap around not only the columns themselves, but also around the edges of the doorway, help create a stronger impression.
Builders generally use circular or square columns in their structures. To create more of an ancient Greek feel to the building, they may use circular columns and white moldings. More modern looks often incorporate square columns and the use of dark stains or vibrant-colored paints.
