THE PROJECT

Project Highlights
  • 21-story mixed-use residential tower with two levels of below-grade parking
  • Luxury amenities on 19th floor
  • Cast-in-place post-tensioned concrete

270 Hennepin is a 21-story, mixed-use residential tower situated in the heart of downtown Minneapolis. With a façade composed of glass and precast panels with inlaid brick, the building successfully achieves its goal of providing a connection between the tall glass structures of the Central Business District with the historic low-rise brick structures of the North Loop neighborhood. The building offers 346 residential units with retail at the first level as well as a large two-story entry space. Two levels of below grade parking and additional parking at Levels 2 and 3 offer 326 spaces. More than 500 bike storage units located adjacent to the parking stalls encourage a clean transportation option for downtown living. A two-story luxury amenities floor at Level 19 includes an indoor pool, sauna, fitness center, yoga studio, club room, and golf-simulator room. An outdoor spa and terrace offer additional amenities and gathering spaces for residents with views of the city.

OUR SOLUTIONS

The structural system is post-tensioned concrete framing and cast-in-place concrete shear walls for resisting lateral forces. Foundations are spread footings bearing on limestone bedrock. MBJ worked closely with the architect to accomplish the design of stacked residential and parking with no transfer columns and beams between the two. The amenities space on Level 19 includes only three transfer columns. Our team was able to thin the slabs from 8” to 7.5” in thickness which resulted in concrete savings and a reduction in foundation loads. MBJ also assisted in minimizing floor to floor heights at the underground levels as well as foundation thicknesses to reduce rock excavation.
