National Construction designed and built a 17,547 square foot office and additive manufacturing facility with a geothermal heating and cooling system and in-floor radiant heating for Midwest Prototyping, now a Prototek Digital Manufacturing company. The office building exterior features cement board siding, Mira Tec trim and a timber frame covered front entry with stone columns. The manufacturing area is a Morton Building structure with a pre-cast flooring system. National later completed two mezzanine-level additions and added an overhead door.
