Plans have been unveiled for a new 10-story office complex to be built at the corner of Main Street and 600 South in downtown Salt Lake City. Named 650 Main and developed by a joint venture of two Texas fi rms, the tower will contain 320,000 square feet of Class A office space.

A pair of Texas-based real estate development firms have announced plans to build a Class A office tower in downtown Salt Lake City. A joint venture consisting of Patrinely Group of Houston and San Antonio-based USAA Real Estate Co. said the complex, dubbed 650 Main, will be a 320,000-square-foot development located at the corner of Main Street and 600 South.

The first-phase office building will consist of 10 levels. Floor plate sizes range from 40,000 rentable square feet on the lower floors (levels 1-4) and 29,500 rentable square feet on the upper floors (levels 5-10).

A release from the partnership said there is the possibility of future expansion of the development, including a 640,000-square-foot tower, adjacent to the 650 Main building at 655 S. West Temple.

Designed by design and architectural firm HOK, the building will have a diverse mix of offerings. It will have both open and private office layouts, floor-to-ceiling glass with 10- and 11-foot ceiling heights to maximize sunlight, outdoor tenant terraces and mountain views. Also included will be fitness center with men’s and women’s locker rooms, bike storage, a private courtyard, flexible conference facilities for small or large groups and a large lobby with a seating area. Additional amenities include an onsite restaurant with indoor and outdoor dining options. The project will be designed for LEED Gold certification.

“We’re excited to be entering this dynamic market with a modern workplace for today’s employees,” said Robert Fields, president and CEO of Patrinely Group, the venture’s managing general partner. “We believe 650 Main provides the next generation of office space to a city consistently recognized as top for business and lifestyle.”

“As Salt Lake City continues to top charts and rankings as one of the best places for business in the country, there continues to be a large demand for office space of this size and caliber downtown, which is why I am very excited to have the Patrinely Group and this development in the city,” said Lara Fritts, director of Salt Lake City’s Department of Economic Development. “650 Main is sure to be a beautiful fixture in the heart of Salt Lake City and attract the high-quality companies looking to expand here.”

Patrinely Group has selected Newmark Grubb ACRES as the office leasing agent for the project. Aaron Jones and David Kelly will lead the leasing and marketing efforts.

“650 Main will be unique in Utah due to its large, efficient floor plates, which are unique to downtown Salt Lake,” said Jones. “In addition to a garage that will have three-per-thousand parking, we are also able to offer direct access to TRAX.  Finally, we will be able to use outdoor patios and the grounds as creative outdoor work space. My team and I are very excited to get to work on this great project.”
