Legacy ER & Urgent Care



Interior Designer

Compacting the programs of a state-licensed emergency facility and a common urgent care clinic, Legacy ER aims to redefine the medical care experience. The architecture explores the spatially expressible relationship between the clinical administration of medicine and the emotional relation between the medical professional, the patient, and the healing environment.

The building integrates the principles of Evidence-Based Design and Sustainability within its spatial, circulatory, and sensory structure. The components of workspaces were designed for peer collaboration, patient accessibility, and data privacy. Patient care areas were crafted for hospitality and treatment efficacy.

The exterior enclosure is an architectural robe of perforated zinc panels with integrated lighting system. The folding panels were seamed to maintain continuous readings of the vertical standing seams. The edge detailing of the panels create zero edges and suggests flight, lightness, precision, and speed.

Relating in contrast to the precise geometries of the exterior, the interior spaces are designed to blur edges and to receive daylight and artificial light softly. Multiple skylights are situated at strategic intersections of the circulatory loop to form a sensible system of way-finding and apertures to the outdoor. The atmospheric quality of the interior continually morphs in response to the natural climatic conditions. The detailing of the interior skylights reads as frameless apertures that puncture the zinc exterior paneling.

As an effect, the building achieves an engaging balance between the aggressive, vigilant presence on the exterior and a tranquil interior ambience, offering a soothing place of respite for patients seeking medical care under distressed conditions.

This is a second building by 5G Studio Collaborative for the same client, Legacy ER. The first building, located in Frisco, Texas was featured on Arch Record online BTS on August 4, 2011. The success of the first building's design, and the exceptional branding and business opportunities it enabled, convinced the client to push forward with an edgy contemporary design to advance the discourse on the design of healing environment.

10 years after opening, the building was honored as one of twenty-five winning projects of The Dallas Architecture Forum 25th Anniversary Design Recognition Awards, an awards program that celebrates twenty-five projects of significance that have improved the social and urban fabric of North Texas since The Forum was founded twenty-five years ago.

“How Legacy ER & Urgent Care is Doing Healthcare Differently”


“An alternative to this grim state of affairs, with broad implications for emergency medical care across the nation, may be found along an unremarkable stretch of parkway in Allen. Here, standing out in the sprawl of cookie-cutter housing developments and strip-mall chain stores, is an object that seems delivered from the realm of science fiction, a mechanical insect of folded zinc planes, jutting angles and perforated screens.”

Mark Lamster, architecture critic of Dallas Morning News and recipient of Texas Society of Architects’ Flowers Medal for promotion of Architecture through Media, wrote in Dallas Morning News lede article titled “The Design Cure”

“This architectural response to a straight-forward planning solution is an exciting vision of how good design represents the intent of a building. . . . The result is a fresh and innovative solution to freestanding urgent care centers and emergency rooms.”

Jury Remark in awarding the project the AIA/AAH National Healthcare Design Award

“What was immediately apparent was the completeness of the solution, striving to address every room with the same level of attention to aesthetics, materials, and detailing. The design is pushing boundaries.”

Jury remark in awarding Contract Magazine’s Interiors Award

“What will the future of American medical care look like? One answer to that question lies amid the suburban sprawl of Allen, Texas, a bedroom community sprouting from the tawny prairie land some 30 miles north of downtown Dallas. . . . For both physicians and patients, the design represents a considerable improvement over the status quo. The typology, moreover, has the capacity to significantly improve access to care, if various regulatory issues are satisfied. As these facilities continue to proliferate, Legacy ER is a welcome example that other freestanding clinics might do well to follow.”

Mark Lamster, architecture critic of Dallas Morning News and Loeb Fellow at the Harvard Graduate School of Design, wrote in Architectural Record magazine, titled “Roadside Attraction: Legacy ER, a freestanding emergency room and urgent-care facility stops traffic”
