The main purpose of gazebo attached to house is to offer shade from the sun. Most modern gazebo is made of wood, which is less expensive than stone or brick structures. Gazebo attached to house is connected to the side of the buildings, usually the houses, and receive part of their structural support of the building. As a result, the backside of attached gazebo lack rear columns that is located on separate gazebo. These gazebos are usually built as an addition to the houses and patio deck areas. Some homeowners build attached gazebo more than their driveways and park under the gazebo. Attached gazebo is also built over the front or rear doors to give a more attractive feel to the entrance of the building.
As its name implies, pergolas of two columns only have two columns that support the structure. Landscape architects often build two-column pergolas for gardens that do not have a lot of space. These pergolas are commonly used as entrances in a garden. The number of columns is the main difference between two-column pergolas and other pergolas since gardeners still wear varieties of two columns with vines and other floral arrangements. However, pergolas of two columns, obviously, do not provide the amount of shade or shelter that other forms of pergolas do.
Pergolas are hexagonal structures with six support columns and are constructed in the shape of a hexagon. These pergolas are useful to cover patio areas with round shape. Most of these types of pergolas are independent structures, although some architects make hexagonal pergolas. However, attached hexagonal pergolas are actually half hexagonal structures. Pergolas similar to the square or rectangular, hexagonal pergolas are able to support, flat style gazebo and curved roofs.
