The 428: "Your Work. Your Way"

428 Minnesota Street  |  St. Paul, Minnesota


KimbleCo was delighted to be selected for a variety of roles on this exciting downtown St. Paul new office project. The 428 is the first building to receive WELL Certification™ in the State of Minnesota at the Gold level by the International WELL Building Institute™ (IWBI™). 

The prestigious distinction was awarded through IWBI’s WELL Building Standard™ (WELL), which is the premier building standard to focus on enhancing people’s health and wellness through the buildings where we live, work and play. The 428 has also been designated as a LEED Silver building, and is the first WELL and LEED certified building in the region.

In its consulting role, KimbleCo developed and managed the building budget and proforma, made application for grant funding for asbestos clean-up, developed and issued RFP’s and negotiated contracts for general contractor and architect, assisted with building the rest of the team, helped to develop brand and marketing, and generally provided consulting and development management services to all aspects of the project from start to finish.

We consulted on the rooftop co-working concept through local, national and global research, development of a business model, procurement of a specialized national consultant, creation of RFP and selection of interior architect and ongoing participation in design, branding and marketing. KimbleCo provided timeline project management for all pre-development requirements necessary to bring the concept on line to correspond with the rest of the building completion.

KimbleCo was also selected to co-list the property for lease with a focus on securing tenants that value the health, wellness and sustainability brand as well as the opportunity for dynamic collaborative rooftop space and conference amenities.

Our client tells us we added value through costs savings, risk mitigation and expertise from our over 50 years of experience that improved the overall development project.
