Pole house construction uses a totally integrated engineering style not normally found in conventional house building. In a pole house, the skeletal structure carries the entire loading of the suspended floors and roof. The skeletal structure is engineered to be independent of wall placement, allowing all of the interior and exterior walls of the pole house to be completely non-load bearing. A pier and piling building is usually nothing more than a pole platform base on which a conventional building is placed. The pier and piling poles do not penetrate above floor level. It is good for pole houses, large diameter wood poles are bolted atop reinforced concrete footings and rise vertically through the entire structure to carry the suspended floor girder beams, floor joists, and the tension ring beam and roofing rafters. The entire engineered skeletal structure becomes an incredibly strong integrated frame.

Diffusion of water through the building envelope is normally not significant for the moisture balance of the indoor air, but different building materials may have significant impact on water absorption speed and capacity. These differences may impact the robustness of an indoor climate to sudden changes in moisture loads. Many everyday activities such as cooking, bathing and clothes drying are also moisture load incidents that challenge the robustness of the house to moisture problems.

The inherent characteristics of a wood house mean you may feel movement at times. In a pole house, the cantilevering areas may react with a very slight sine wave (vibration) when a "live" load is present, sending a slight sensation of movement through the wood framework. This is normal. The live load can be the result of heavy wind or a person jumping up and down in a cantilevered area of the home. Your new pole house will not sway wildly or make you seasick. Humid buildings are widely acknowledged as a serious health risk for the occupants. A balance between moisture sources and moisture removal, primarily due to ventilation with outdoor air, is vital to avoid infestation with mould, house dust mites and other moisture related problems.

The ability of the houses to absorb water in their structures after these experimentally created humidifying incidents was assessed based on mathematical models. Moisture absorption was most significant in the old masonry house during the first four hours after the steam was added. After this period the modern masonry house, with the slowly reacting concrete, had the highest absorption. At all times the least absorption was seen in the wooden house. Green house plans are growing in popularity and represent a design philosophy bent on creating energy-savings beginning with the home design. Through the use of passive solar, smart material choices and cutting-edge design, these homes will help you cut down on utility bills and leave a lighter footprint as you build your new home.
