Jefferson National Expansion Memorial Museum Store Opens

As a key component of the CityArchRiver led national monument museum renovation, the new Jefferson National Expansion Memorial Museum Store captivates visitors with its vastness and light. Its design ties seamlessly into the Arch Lobby; modern yet approachable, a space worthy of representing the St. Louis Arch. The quality of the space and clear-span expanse disguises the store’s subterranean setting.

The store’s central location, and advanced construction schedule relative to the larger museum project, proved to be a complex task. Trivers guided the design and construction of the retail white-box through the many multifaceted coordination concerns innate to an infill project within a still continuously operating national monument and visitor center.

Unknown to many is the complexity of what lies beneath. The design team took what originally had been an IMAX theatre and inserted three new programmatic levels of storage, employee offices, and the museum store itself.

Trivers partnered with Cooper Robertson on the white-box scope and Anderson Hallas on the construction administration fit-out of the 4,000 SF space.




Hotel Indigo Underway in Downtown St. Louis

Trivers Associates’ hospitality work dates back more than 20 years. Our St. Louis-area hotels alone total nearly 1500 rooms, 2,000,000 square feet and over $180M in construction cost. These projects include the Westin Hotel at Cupples Station, Embassy Suites at the Laurel and the conversion of the Adam’s Mark Hotel into the Hyatt Regency St. Louis at the Arch.

Our latest hotel project is in partnership with ViaNova Development and will finally revitalize the long vacant historic LaSalle Building in the heart of downtown St. Louis. The project is currently planned to open as a Hotel Indigo. Originally designed in 1909 by Isaac Taylor, the LaSalle Building rises 13-stories and features bay windows beginning at the third story with terra cotta and cast iron details at the first and second stories. Trivers is leading the design team through a full rehabilitation of this unique building as well as a renovation of the adjacent office building for use as an 88-key hotel. Exterior improvements on the LaSalle building include full window replacement for all upper stories, masonry and terra cotta repair, roof replacement, and a new rooftop bar with exterior patio. The adjacent office building will receive a completely new façade meant to deliver a modern interpretation of the historic bay windows on the LaSalle building. Trivers also served as historic consultant on the project working closely with the Missouri State Historic Preservation Office and the National Park Service to meet the Secretary of the Interior’s Standards for Rehabilitation.

The Hotel Indigo flag is particularly well suited for this site as the required development of a neighborhood story utilizes a building’s placement within a city as inspiration for the design. With no shortage of historic material, the design team worked with the Owner and Hotel Indigo brand representatives to create a narrative focused on the history of transportation in St. Louis which then acted a lens through which the interior design was developed. The program includes a full restaurant and bar on the first level, meeting rooms and suites on the second and third levels, a fitness center and specialty roof top bar. Selective demolition is underway with full construction anticipated to begin this spring.

Team members include Nehring Design, KPFF Consulting Engineers, G+W Engineering, Civil Design, Inc. and KH Lemp.




Adam Aronson Fine Arts Center Receives AIA Central States Design Honor Award

The American Institute of Architects Central States Region has honored the Adam Aronson Fine Arts Center at Laumeier Sculpture Park with a 2016 Design Honor Award in the Excellence in Architecture category. Principal Joel Fuoss, AIA, received the award at the AIA Kansas + Central States Region Conference, held October 20 in Manhattan, Kansas. The Aronson project was previously the recipient of two AIA St. Louis awards – a Merit Award in the Architecture category (2015) and a Distinguished Award in the Unbuilt category (2013).


Laumeier Sculpture Park is one of the most prestigious open-air museums in the country. The new Adam Aronson Fine Arts Center (AAFAC) was designed in an effort to display artwork year-round in a controlled environment and enhance the ability to provide high-quality learning experiences for the greater St. Louis community and visitors from all over the world.
