This office for general dentistry is designed for a relatively large site that permits expansion of building and parking in the future. The Owners express a wish to design building and site using sustainable, green ideas where practical. Our response is to focus on energy conservation: preliminary ideas include geothermal heating and cooling, highly insulated envelope, and daylighting. The Owner has approved site and building sketches; next steps are to draw the building interior and add detail to 3D massing of the envelope. Progress on this project is posted on the page Dental Office in Northern Minnesota. Revised site and floor plan drawings have been added. While 3D building design progresses 3D design of treatment rooms is underway.
