Modular additions are usually side and 2nd story additions to homes that are pre-fabricated at the facilities. General characteristics of a modular home apply. For a 2nd story modular addition the existing house should have a sound structure as modular rooms are 30%+ heavier than the same stick-built. Modular additions are built in the facility, brought to the site and “dropped” by crane on the new location. It is necessary to have a general contractor to supervise the project as there is always some work to tie new rooms into an existing house. Even though it is assumed that modular additions are less expensive than traditional stick built this is rarely true when compared by square footage. The buyer would generally get more wood and better insulation plus benefits of controlled environment but total cost of the contract would be about the same. ==See also== *Prefabricated home *Manufactured housing *Stick-built home *NTA Inc - Third Party Inspection/Design Review Agency 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Modular Addition」の詳細全文を読む スポンサード リンク
