Cabin Foundation Types

Open Foundation

• An open foundation consists of the cabin resting on posts spaced apart along the inside area of the foundation with other posts lining the outer rim, which provides added support to the floor as well as the overall structure. Due to the spacing of the posts, air flows freely underneath the cabin with no potential for moisture buildup underneath the floor. Although not typically used in constructing homes, the open foundation style has been common for hundreds of years with hunters and sportsmen alike as well as praised as one of the simplest methods in building cabins. Home porches and decks offer a common example of the open foundation style.

Pier Foundation

• The pier foundation, a redesign of the open style, is similar in construction except that instead of allowing airflow, trim or skirting, cover all of the open areas. Possible skirting options include plywood, lattice or sheet metal. which gives the cabin an attractive, more solid appearance while providing additional storage space for the occupants. A grate or vent placed on the sides of a pier foundation prevent excessive moisture buildup. An example of a pier foundation can be found in the support structure used in mobile homes, complete with examples of skirting materials.

Continuous Wall Foundation

• A continuous wall foundation is another type of foundation commonly used with cabins. The cabin rests on a solid wall that closes off airflow underneath the structure. It provides all of the benefits of the pier foundation with added strength in the construction. This foundation is usually constructed of poured concrete, brick or stonework. As with the pier type, adding vents or grates for ventilation prevent moisture buildup. An example of the continuous wall can be found in most modern homes without basements.

Basement Foundation

• Many intricately built cabins, and cabins used as an actual residence, utilize a basement foundation. This foundation allows the cabin to rest on a functioning room or storage area designed to actually be part of the home. It grants more strength in the design than all of the other foundations and keeps moisture under control if adequately ventilated. It is normally constructed out of stone, brick or concrete and built underground, although it can be built above ground as well in some cases.
