Dallas' Uptown district is getting a new high-rise development.

The project at Cedar Springs Road and Routh Street just south of Turtle Creek is the largest new development proposed for the booming neighborhood north of downtown Dallas.

Minnesota-based developer Ryan Cos. is teaming up with Dallas architect GFF and Greenway Investments to build the office, residential, hotel and retail buildings.

"This site is impossible to miss — it's the heart of Uptown," said Paul Rowsey, Ryan's vice president of real estate development. "It's a prime location that bridges the areas between the Quadrangle and the Katy Trail and the Crescent to the south.

"All arrows point to this site."

The 4-acre project includes architect GFF's existing building on Fairmount Street. The remainder of the block will be redeveloped with an 18-story office tower, a 22-story residential high-rise, a luxury hotel and retail space.

"There aren't many development sites this large in Uptown," Rowsey said. "This is a unique opportunity to not only to build but create a destination for the entire area."

Rowsey joined Ryan last year after working on the new $400 million Union development on Field Street in Uptown. The huge office, residential and retail project just opened and is already significantly leased.

Ryan Cos. is an 80-year-old real estate company with 16 offices and projects in 38 states. The company builds office, industrial, health care, mixed-use, hospitality and residential developments.

Ryan is already working on a new office development in Frisco and has projects in Austin and San Antonio.

GFF and Greenway Investments teamed up with Ryan to develop the Uptown property after interviewing several different developers.

"Now we are coming forward with a plan for the entire property that will position it to be one of the prime properties in Uptown for decades," said GFF president Evan Beattie.

GFF and Greenway have been working on plans for the redevelopment for several years.

Plans call for the office tower to be built on Cedar Springs at Routh, with the residential building to the east across from the Quadrangle. A high-rise hotel would occupy the corner of Cedar Springs and Fairmount, next door to GFF's building.

Much of the block is now occupied by small retail buildings and surface parking lots.

Ryan and GFF plan to build a park through the center of the new high-rise complex and put all the parking underground.

"Our plan has a lot coverage of 55%," Beattie said. "We have over an acre of open space on the site.

"The area adjacent to our existing office building will have small-scale restaurants, and the ground floor of our building will be converted to retail."

Ryan hopes to start construction on the development next year, with the first phase opening in late 2022 and early 2023.

The companies first must seek zoning changes for the planned project.

The development is one of four new high-rise projects on the way in that area of Uptown.

Just a block away, San Antonio-based developer Kairoi Residential plans a 12-story apartment tower on Maple Avenue across from the Crescent. And developer Granite Properties has announced plans for a more than 25-story office tower on the west side of Cedar Springs Road at Maple. Developer Alamo Manhattan has already begun construction on a 14-story Marriott Hotel in the same area.
