The City of Carmel and Philadelphia-based Rubenstein Partners are developing plans to transform the eastern half of Parkwood Crossing into a neighborhood with office space, housing, restaurants, retail, recreation and a new street grid. Parkwood Crossing is the largest office complex in the metropolitan area. It has eight multistory buildings, 1.2 million square feet of rentable office space and an occupancy rate of 76%. The project, called Carmel Gateway, would incorporate Parkwood Crossing’s three largest office buildings, a large parking lot and a pond into a mixed-use development that would add 1.2 million square feet of housing with nearly 1,200 apartment units, more than 86,000 square feet of retail space and 87,000 square feet of hotel space.
