The design integrated improved ADA accessibility and new conference room doors that open onto a courtyard. The total square footage is 3,500 square feet. The stunning addition of a rooftop patio on the historic Ballpark building in downtown Denver created a vibrant, inviting space for office employees to enjoy Denver’s cherished views and meet with clients in an alternative atmosphere.

Featured Projects

The KSL Capital building was a perfect challenge for Venture. They were tasked to cultivate a highly original concept that mirrored the company’s unique and exclusive approach. The space was intended to speak to both flair and refinement, be highly functional, and be team conducive and relaxing. Circular conference rooms with window walls, various modules with sliding glass doors, and a kitchen and lounge area with window-facing countertops accomplished the job nicely.

Applied Control is a headquarters facility for the local representative of a large national business based in South Metro Denver, and it fuses the clients’ practical needs with a functional and bright design. The work kept in mind future expansion, so the facility can adequately serve the growth of the company.

Featured Projects

When Humphries Poli renovated the single-story warehouse near Denver’s Coors field, their vision was to craft a unique and inspiring office space for creative thinkers in the advertising business. Original bow-string trusses from the warehouse were highlighted, and a partial second floor was placed into the building for conferences and meetings. Constructed as a permeable cloud, the upper level can compress or open lower level volumes. The lighting scheme, situated in slashed diagonals, illuminates the high-ceilinged wood above. Humphries Poli truly designed this space to complement the needs and energy of the people working within it, a signature component of the design firm’s personal touch. Recognized with the Historic Denver Community Preservation Award and LEED Gold certified, the American Woodmen Insurance Building’s new headquarters is modern, elegant and sleek.

Featured Projects

The Cachematrix building is a wonderful alternative to the classic stereotypes that financial workers reside in lavish Wall Street-esque structures. The project required smart budgeting, as the client had $20 per square foot to spend. Box Studios intelligently identified the zones of the space that merited the most investment and executed inspired design for a cost-effective price. The result is a calm, elegant environment with tasteful uses of glass, circularity, and flowing transitions between rooms. Megastar Financial showcases Box Studio’s ability to transform pre-existing buildings into entirely new experiences. Originally an old dairy in the Golden Triangle area of downtown Denver, the 35k-square-foot structure required careful planning, an exterior facelift, a more efficient layout, and a creative approach to introducing more light into the interior. The result is a bright, inviting space that feels both youthful and rooted in history.

Featured Projects

Modernizing the original Colonnade Center, which was occupied by seven federal agencies for close to 30 years, required both an innovative new vision and a dedication to expressing the sustainability and public visibility the federal government valued. What is now the Cesar E. Chavez building houses government offices using a security-hardened exterior envelope that’s engineered for a 100-year lifespan, and a new aluminum and glass curtain wall to reduce energy consumption by 32 percent. Tryba even integrated recycled material, including terrazzo made from local beer bottles and steel. The 330k-square-foot Colorado Google headquarters is in the works, and Tryba is at the helm. The campus, which is currently home to 300 employees will be expanded to make space for up to 1,000. The goal is to cultivate a creativity-inspiring and collaboration-inducing environment that interplays with the natural surroundings. Open floor plans and efficient building envelopes are key.

Featured Projects

The Boathouse St. Charles Town Offices were designed to encourage interconnectedness, both visually and physically. Semple Brown Design also wanted to integrate the strong natural connection to the Platte River and the Cherry Creek Trail, which are visible from the communal meeting and lounge spaces via glass walls that offer not only exceptional views but also wonderful, natural light. Professional transparency is also evident in the open layout, which provides ample room for impromptu conversations. The style integrates industrial, professional, and rustic into one innovative and inviting final product. The design of IMA Financial Group’s new headquarters was intended to be structured around the company’s goal of being the “Healthiest Employer in Denver,” and they wanted their active lifestyle to be honored through concept, design, and layout. Collaborative team working spaces, the fitness center, and an enhanced connecting staircase encourage the intent nicely, and an elegant, contemporary interior makes the structure feel both professional and cozy.

For the Alliance for Sustainable Colorado, Gensler carefully crafted a design concept for a high performance renovation of their office space in downtown Denver. With this project, Gensler tended to the client’s vision of a space that would specifically attract tenants who wanted to facilitate sustainability through collaboration. The result, a multi-tenant nonprofit center where tenants are spatially connected through an open, flexible design concept, includes a restored original entry, a brand new lobby, and gorgeous, exposed wood wall and ceiling beams. The new construction on Denver’s Global Analytics Design Firm fuses two offices into one, maximizing the open concept effect to create an urban, modern aesthetic. Daylight and windows were made accessible to everyone by positioning the enclosed offices around a central core. Other highlights include a stunning, two-story curtain wall, lively collaboration areas, and a fresh color palette that integrates seamlessly into the urban appeal.

Featured Projects

The Triangle Building at 16 Wewatta Street is eye-catching for several reasons. It’s not just the sleek urban design and stand-out patterns, but the way each side of the structure is enriched by a public space. This single prism of glass is a viewfinder’s focal point, from both the corner of Wewatta Street and the Millennium Bridge. This building engages the surrounding area and brings another sophisticated, professional visual into Denver’s skyline. A LEED Gold Certification was awarded for exceptional quality and innovation in green building practices. It houses Liberty Global and the first WeWork in Colorado. The 350k square feet of the Triangle Building was completed in 2016 for $45M. Adding two new wing buildings to Denver’s historic Union Station required a well thought out strategy that would keep attention on the valued urban centerpiece while cultivating community anchoring space and celebrating the surrounding area. Anderson Mason Dale designed the wing buildings with the intention of striking a balance between the lower downtown red brick warehouses, the gray terra cotta and cleft rhyolite of the station, and modern new developments. They succeeded with a contemporary aesthetic that recreates components of neighboring buildings. Using the basic form of a simple glass box, the wings have a vibrant, inviting, urban glow. The project was completed in 2014 for $37.4M.
