Commercial Building Plans: Quality commercial buildings are crucial to redeveloping existing urban centers. They provide the environment that entrepreneurs and established business leaders need to breathe life into downtowns everywhere. Our commercial floor plans come from our sister Web site, TNDhomes.com, and are mixed-use designs, which combine commercial or retail space on the ground level with sought-after living space on the upper levels. These commercial floor plans are "design sets;" that is, they include dimensioned front, side, and rear elevations, floor plans, and details. Some additional design work will need to be completed by a local architect in order to align the plan with your local building codes and soil conditions, since they do not include foundation, structural, electrical or other construction details.
