Indoor Air Quality directly affects our health. The average American home has very poor air quality and occupants suffer serious health consequences for it.

OSH builds and remodels homes to the highest standard of Indoor Air Quality with high performance ventilation systems. Occupants can feel the difference ...take a deep breath. It feels like the great outdoors.

EPA Indoor Air Plus checklist


We design, engineer and build homes using the latest air quality science  and best practices codified by national and international standards organizations like ANSI and ISO. We utilize guidelines and engineering standards published by ASHRAE.
















We follow the EPA's Indoor Air Plus standards of best building practices to insure optimum air quality. We install ventilation systems with high performance filters to provide continuous, fresh, filtered air all the time.
