What Is Formativ Building in RiNo?
At 3850 Blake Street, the Formativ building in RiNo is a 16-story multifamily development planned as a 310-unit residential community in Denver’s River North Art District.
The project is designed as Class A housing with studios, one-bedroom, and two-bedroom apartments across 275,608 square feet.
Its unit strategy centers on efficient layouts and small-format living, with average apartment sizes reported at under 600 square feet.
Formativ presents the building as an attainable housing response within central Denver.
Reports indicate a significant share of units will serve households at workforce and below-market income levels, supported by compact design and transit adjacency.
The broader multifamily investment backdrop has drawn attention from REITs, with net operating income growth topping 3% in 2024.
Construction financing reached $65.5 million in July 2025.
Groundbreaking followed in June 2025.
Topping out was completed in March 2026, and opening is projected in 2027.
The project is on track to welcome its first residents in Q2 of 2027.
Where Is the RiNo Apartment Project Located?
The Residences at RiNo is planned for the intersection of Brighton Boulevard and 43rd Street in Denver’s River North Arts District. This places the midrise development at a prominent entry point into RiNo.
The site sits along the Brighton gateway, a visible corridor tied to redevelopment and neighborhood access. The project is also positioned within North Wynkoop, a larger mixed-use framework shaping the surrounding area. Denver’s broader development wave also includes the approved River Mile project, a $1 billion downtown investment aimed at expanding mixed-use growth and public space.
Site Context
Rather than occupying RiNo’s central warehouse core, the property stands nearer the district’s northern approach in Denver, Colorado. That placement gives it a clear street identity and strengthens its role in arrivals into RiNo.
- Brighton Boulevard and 43rd Street mark the site.
- The project lies in Denver’s River North Arts District.
- North Wynkoop provides the broader development context.
- The corridor is a major RiNo redevelopment zone.
What Will the New RiNo Phase Include?
Rising within RiNo’s next wave of dense urban housing, the new phase is planned as a multifamily buildout with a substantial residential program. It is expected to include studio, one-bedroom, and two-bedroom layouts.
Reports point to 246 homes at AVA RiNo, while the broader $400 million second phase is also described elsewhere as a larger luxury complex. Planned resident amenities include a pool, fitness center, two courtyards, lounge, bike room, rooftop deck, pet park, and pet spa.
| Feature | Planned element |
|---|---|
| Homes | Studio to two-bedroom units |
| Wellness | Pool and fitness center |
| Social space | Courtyards and resident lounge |
| Pet features | Rooftop park and pet spa |
| Public sphere | Coffee shop supports community activation |
The structure is expected to use below-grade parking. It would also include a concrete podium with three wood-framed levels above.
When Will the RiNo Apartments Open?
Current reporting places Ave Station House on track to open in 2028. That year is cited consistently in both groundbreaking coverage and the developer-backed AVE Living listing.
That makes 2028 the clearest answer right now. No month or quarter has been confirmed.
With vertical construction underway after spring 2026 groundbreaking activity, the timeline points to a multi-year build. Residents are not expected to move in until the project is complete.
Key Timing Signals
- Opening is targeted for 2028 across cited reporting.
- The project has moved beyond planning into active construction.
- Its 13-story, 301-unit scale supports a two-year-plus build schedule.
- Ground-floor retail could affect final delivery timing.
At 1485 40th St., the $103.8 million project appears positioned to meet market demand. For now, the most supportable phrasing is that the apartments are expected to open in 2028.
How Does This Project Fit RiNo’s Development Pipeline?
Crowding into a fast-thickening corridor, Ave Station House fits RiNo’s development pipeline as one of several large apartment projects advancing at once near the 38th and Blake transit hub.
Its 301 units and roughly 6,000 square feet of retail place it beside 3850 Blake, Rowan, Novel RiNo, and other sizable multifamily developments now moving through overlapping stages.
This pattern reflects transit clustering rather than isolated infill.
Projects across from or near the A-Line station are being built at higher densities, with mid-rise and high-rise formats supported by rail access and mixed-use street activation.
Ave enters a pipeline that spans luxury, attainable, flexible-stay, and workforce-oriented housing.
That mix broadens district appeal, but it also raises attention on market absorption as RiNo adds hundreds of units per project, not dozens.
Assessment
Formativ’s $400 million RiNo apartment project signals another high-stakes phase in Denver’s fast-changing urban core. The development adds substantial housing, retail, and mixed-use space to one of the city’s most active construction pipelines.
Its scale underscores continuing investor confidence in RiNo, even as affordability, infrastructure pressure, and neighborhood transformation remain central concerns.
As the phased buildout advances toward opening, the project is positioned to become a defining addition to the district’s next development cycle.
