With an area of 300,000 square feet and a height of 32 feet, Prairie Business Park Warehouse III is one of the largest warehouses that R&R Realty Group has built in the company's 35-year history. 

Located along South James Street in Grimes, just south of two of R&R Realty's other warehouses, the new building was designed to accommodate a variety of potential tenants. 

Like its predecessors, the building started as a box-shaped blank canvas. But it could soon house a distribution center, offices, a youth sports complex — or almost anything else a tenant could dream up.

From the beginning of 2014 to the end of 2018, warehouse inventory in the Des Moines metro grew by nearly 5.7 million square feet, or 18%, according to the most recent year-to-year data from CBRE/Hubbell Commercial. That's more than five times what the metro added in the previous five-year period.
