Developers Shames Makovsky have moved a proposed 673-foot spiral observation tower in downtown Denver into the design and engineering phase [1].
The project aims to establish one of the tallest structures in the city, creating a new landmark attraction for both residents and tourists. By introducing a high-altitude observation deck, the developers intend to diversify the downtown skyline and increase foot traffic to the area.
The proposed site for the tower is located at 1,546 California Street and 1,555 Welton Street [1]. This specific location in the heart of the city places the structure within a primary corridor of Denver's commercial and urban center.
As the project enters the engineering stage, the firm will focus on the structural requirements of the spiral design. This phase is critical for determining how the tower will withstand wind loads and integrate with the existing urban infrastructure of the U.S. city.
The development is intended to serve as a destination point, providing panoramic views of the surrounding region. While the project is currently in the design phase, the goal remains to create a signature architectural piece that distinguishes the downtown area from other metropolitan hubs.
Reporting on the project's progress was noted as of Aug. 6, 2026 [2]. Shames Makovsky said it will continue to refine the blueprints and technical specifications required for city approval and eventual construction.

The transition into the design and engineering phase signals a move from conceptual planning to technical viability. If completed, the tower would shift Denver's architectural profile by adding a dedicated tourist attraction, potentially mirroring the economic impact of observation decks in other major U.S. cities by drawing visitors into the downtown core.
