In the lifecycle of Denver real estate, Upton Residences is not just another building; it is a market-correcting event. For over a decade—specifically since the completion of The Spire in 2009—Downtown Denver has suffered from a severe lack of new, large-scale for-sale inventory. While luxury rental towers have risen by the dozen, the opportunity for ownership in the core has been stifled by construction defect litigation risks and high land costs.
Upton Residences, developed by the Vancouver-based Amacon, ends this drought. Rising at 18th and Glenarm, this dual-tower development delivers 461 new residences to a market starving for inventory. It represents the "missing middle" of the high-rise market: attainable luxury that bridges the gap between the aging resale inventory of the 2000s and the ultra-luxury price points of developments like the Four Seasons or the new Waldorf Astoria.
This report provides a granular analysis of Upton Residences, dissecting its architectural merits, the realities of its construction timeline, and its investment viability in the shifting landscape of 2026.
To understand the value of Upton, one must understand the structural constraints of the Denver market.
For years, a buyer seeking a modern high-rise condo in Denver faced a binary choice: pay a premium for The Coloradan (Union Station) or settle for 15-year-old finishes in older buildings. Upton disrupts this dynamic by offering brand-new construction at price points starting in the low $400,000s. This aggressive pricing strategy targets the "laptop class"—young professionals and first-time buyers who have been priced out of the single-family market but refuse to rent.
Upton anchors a neighborhood transition. Situated on what was formerly a surface parking lot (a "parking crater"), the project physically and psychologically connects the Central Business District (CBD) with the historic, tree-lined streets of Uptown (North Capitol Hill). It creates a continuous urban fabric where residents can work in the financial district and dine on "Restaurant Row" (17th Avenue) without ever needing a car.
The site at 525 18th Street offers a unique "locational arbitrage"—the density of downtown with the flavor of a neighborhood.
The Walk Score here is elite. Residents are geographically positioned to access:
Dining: The building is blocks away from 17th Avenue’s "Restaurant Row," home to staples like Steuben’s, Ace Eat Serve, and Watercourse Foods.
Coffee Culture: This micro-neighborhood is a caffeine hub. Novo Coffee on Glenarm is a local institution, while Crema and Little Owl provide high-end third-wave options within walking distance.
Entertainment: The proximity to the Ogden Theatre and Fillmore Auditorium on Colfax offers walkable access to premier live music venues, a major draw for the target demographic.
Proximity to the light rail on California and Stout Streets ensures connectivity to Union Station (and the A-Line to the airport) without the noise impact of living directly on the tracks.
A true expert analysis must look beyond the brochure. Upton consists of two towers—a 38-story South Tower and a 32-story North Tower—connected by an 8-story podium.
Designed by Davis Partnership Architects, the building eschews the heavy masonry common in LoDo for a light, ethereal aesthetic. The "Polar White" exterior and extensive glass are designed to capture and reflect Denver’s intense high-altitude sunlight. The podium is not just a parking garage; it is the social engine of the building, hosting retail and amenities that activate the street corner.
In mid-2025, the project made headlines due to a legal dispute between the developer, Amacon, and a concrete subcontractor regarding work on the upper levels.
The Reality: There were allegations of unauthorized removal of structural shoring, leading to remedial work on the 38th-floor slab.
The Resolution: It is critical for buyers to know that this was identified, work was halted, and new contractors were brought in. Engineering reports have subsequently cleared the building’s safety.
The Expert Take: While scary in headlines, this level of scrutiny often results in a more inspected building than one where issues are hidden. However, savvy buyers should request the "structural letter of comfort" from the engineer of record as part of their due diligence documents.
Amacon’s background in high-density markets like Vancouver is evident in the floor plans. They are efficient, maximizing utility in smaller square footages.
Studios & 1-Bedrooms: These are the volume drivers, designed for efficiency.
The Penthouse Collection: Located on floors 36-38 of the South Tower, these units offer sprawling layouts and terraces that compete with luxury single-family homes.
Interior Palettes: Buyers choose between "Avenue" (light, airy, Scandi-modern) and "Boulevard" (dark, rich, moody).
Specifications:
Kitchens: Premium units feature Bosch appliance packages, including integrated panel refrigerators and induction cooktops—a forward-thinking choice for indoor air quality and performance.
Flooring: Engineered hardwood in living areas (and bedrooms in Premium units) elevates the feel beyond standard rental grade.
The orientation of the towers maximizes view corridors. West-facing units offer the coveted Front Range mountain views, while city-facing units capture the twinkling lights of the CBD skyline.
Upton dedicates nearly 18,000 square feet to amenities, acknowledging that for many residents, the building is their living room.
The Pool Deck: An outdoor pool and hot tub serve as the summer social hub, complete with fire pits and grilling stations.
Co-Working: Recognizing the hybrid work era, the building includes a dedicated co-working lounge with private meeting rooms, allowing residents to separate "home" from "office" without leaving the building.
Wellness: A fully equipped fitness center rivals commercial gyms, adding monthly value by negating the need for a separate membership.
Guest Suite: A reservable guest suite allows owners of smaller units to host family comfortably—a smart, high-value amenity.
Entry Level: Starting in the $300s/$400s, Upton offers a lower barrier to entry than almost any other new construction in the city.
Price Per Square Foot: Expect pricing to average between $700 - $900 PSF, positioning it above older resale product (Spire) but below the boutique luxury of Cherry Creek (Waldorf Astoria).
Short-Term Rentals (Airbnb): Buyers must be aware that Denver enforces a primary residence rule for short-term rentals. You cannot buy a unit here purely as an Airbnb investment unless you live in it.
Long-Term Rentals: For investors, the play is appreciation and equity build. With current interest rates, cash-flowing a unit with 20% down is challenging. The "win" comes from holding a scarcity asset in a growing city.
HOA dues are estimated in the $0.70 - $0.80 per square foot range. This is standard for a full-service building with a pool and 24-hour concierge.
Upton Residences is a calculated bet on the future of Downtown Denver. It offers a product that simply doesn't exist elsewhere: new, warranty-backed construction at a price point accessible to the upper-middle class.
For the young professional, it is a lifestyle upgrade. For the downsizer, it is a vibrant, low-maintenance alternative to the suburbs. While the construction delays were a hurdle, the project remains the most significant addition to the skyline in a generation.
Don't Navigate the Pre-Construction Maze Alone
Buying pre-construction requires a specific set of eyes. You need an advocate to help you navigate floor plan selection, understand the view corridors, and ensure you are protected during the contract phase. The sales team works for the developer; I work for you.

Q: When will Upton Residences be completed?
A: Delivery is currently targeted for early to mid-2026.
Q: Can I rent out my unit on Airbnb?
A: No, unless it is your primary residence. Denver has strict laws prohibiting short-term rentals in non-owner-occupied properties, and the building likely has additional lease term restrictions (e.g., 30-day minimums).
Q: Is parking included?
A: Parking availability depends on the specific unit type. Larger units typically include a deeded space, while smaller studios may have waitlist options or no parking. The building features an 8-story parking podium.
Q: What are the HOA fees?
A: Fees are estimated around $0.70 - $0.80 per square foot per month. This covers the 24-hour concierge, pool maintenance, fitness center, building insurance, water, sewer, and trash.
Q: Is the building safe after the construction news?
A: Yes. While there was a dispute regarding concrete work in 2025, the developer has since retained new contractors and stated that engineering inspections have confirmed the structural integrity of the building.
