The eye-catching Alvera Apartments have added 193 units to one of the most vibrant neighborhoods in Minnesota’s capital city. The project presented several challenges, but the award-winning results prove we’re just beginning to understand the possibilities of modular construction.
Overcoming the challenges
The challenges were significant: Bedrock three feet below the surface meant underground parking wasn't feasible; the site's location along one of the busiest traffic corridors in the state meant construction would be complicated; and the lot itself, narrower at the front and wider at the back, would make design difficult.
The solutions to these challenges came from creative thinking and strong collaboration between Minneapolis-based DJR Architecture & Design and RISE Modular, an off-site construction company based in the Twin Cities area.
Together, they created a design for modular units, which maximizes the oddly shaped lot. Assembling the modules off-site sped up construction to a mere 13 months, as opposed to the 18 to 24 months that would have been standard otherwise. Once modules were complete, the building rose quickly. Storing a minimum of modules on a nearby lot minimized the impact on the neighborhood, and the whole building came together in less than three weeks.
And with the close-to-the-surface bedrock challenging underground parking and a narrow lot challenging above-grade parking, they opted for a two-story semi-automated parking system that takes advantage of vertical space in the podium. In total, they were able to add 102 parking spots. But that’s not all. This non-traditional parking solution also allowed for an additional 30 units, which was one of the keys to making the building financially viable.
Long-term benefits
Off-site construction didn’t just improve the construction phase with a faster schedule and less disruption to the neighborhood, it also resulted in a better-quality building. The structural soundness of each module improves the experience for residents by helping to create quieter living environments, while the modular construction resulted in a tighter building envelope — one that's equipped to hold up long-term to Minnesota’s frigid-to-humid climate
Supporting that building envelope are 100 Series windows and doors, which were installed by RISE Modular as the modules were built. Made of Fibrex® composite material, this product line has matching sight lines and glass setbacks across window types allowing for mixing and matching via a seamless joining system that lends itself to commercial applications. The Easy Connect Joining System allows for connecting units onsite or at the factory. Find this option available with both 100 Series and A-Series product lines.
Setting a new standard
The building was the first Type 3A modular building constructed in the area. Its seven stories include two in the concrete podium and five made of stacked modules. DJR Architecture & Design worked closely with the City of St. Paul to navigate zoning, planning, and inspection processes, and the result is more than just this building — it's a path that future modular projects can follow.

A mixed-use building that balances public and private life
Although housing was the greatest need in a bustling Bozeman neighborhood, zoning restrictions required a new building to include mixed residential and commercial uses. Here’s how the architect came up with an award-winning solution.
