What if our hospitals, clinics, and care facilities were not just places to treat illness but tools for healing? In this episode of The Architecture of Healing, host Chase Miller sits down with Dr. Addie Abushousheh, designer, researcher, and environmental gerontologist whose work bridges neuroscience, design, and organizational leadership. Their conversation explores how the built environment shapes human capability, recovery, and dignity, and why designing for vulnerability means designing for all of us.
From Architecture to Environmental Gerontology
Addie’s path to healthcare design began as an aspiring architect fascinated by the way humans interact with their environments. Her early studies took an unexpected turn when mentors exposed her to genetics, cognitive science, and applied physics; disciplines that deepened her curiosity about how people function physiologically and psychologically within space.
Rather than accepting the notion that architecture alone could “shape behavior,” she pursued a dual degree in Organizational Development and Leadership Studies alongside architecture. “Buildings,” she explains, “either act as barriers or facilitators.” Her interest in how cognition, injury, and vulnerability intersect with design led her to work hands-on in a traumatic brain injury unit, studying the rhythms of staff and patients. There, she learned how thoughtful environments can either empower or hinder human potential.
The Environment as a Prosthetic
That experience reframed how Addie thought about safety, autonomy, and design. For patients with brain injuries, even subtle design cues, color contrast, spatial layout, or the intuitive use of a handle or switch could determine whether a space was enabling or disabling. “If we design the environment as a prosthetic,” she says, “we can reduce reliance on staff and help people maintain or even enhance their functioning.”
This mindset expanded beyond rehabilitation units to long-term care, residential settings, and hospitals. Addie describes the built environment as a therapeutic instrument, capable of reinforcing the body and mind’s natural recovery systems when it’s designed with empathy and evidence.
The Competence Press Model: Finding the Sweet Spot
Addie draws on the Competence Press Model, developed by Powell Lawton, which maps personal capability against environmental complexity. Every individual, she explains, thrives within a “zone of adaptation.” Too simple an environment can under-stimulate; too complex can overwhelm.
Her metaphor is vivid: “If you’re a black-diamond skier, the bunny hill will bore you. But if you’re a beginner, the black diamond will terrify you.” The same holds true in healthcare design, spaces must challenge and support patients at the right level to foster growth, independence, and well-being.
The four M’s in Age-Friendly Health Systems
Addie’s work also connects to national initiatives like the Age-Friendly Health Systems framework from CMS, built around the “Four Ms”: mentation, medication, mobility, and what matters most. She argues for a fifth, “multi-complexity” to reflect the layered realities of aging.
Crucially, the Four M’s initiative lacks environmental standards. Yet research in environmental gerontology and evidence-based design already demonstrates how the physical environment directly impacts outcomes in these four domains. “We have decades of data,” she says, “showing that environments influence cognition, falls, medication management, and emotional well-being. But the built environment is still treated as an afterthought.”
Building the Business Case for Healing Design
One of the biggest challenges in advancing evidence-based design, Addie notes, is the business case. Healthcare leaders readily invest in new clinical models or technology but often struggle to quantify the ROI of environmental design.
Her approach blends management principles with data analytics. “If you value something, you evaluate it,” she reminds. Falls, staff turnover, medication errors, all have measurable costs. When those metrics are mapped against design interventions, the financial justification becomes clear.
Addie advocates integrating an “evidence-based design sheet” into construction documents so that valuable design elements aren’t cut during value engineering. Even small changes, a contrasting floor color, a visible clock, or residential-style furnishings in a waiting area can lower stress, reduce confusion, and improve satisfaction.
Designing for Dementia—and for Everyone
One of her projects, a Dementia-Friendly Waiting Room, proved that simple, affordable interventions can transform patient experience. By adjusting lighting, furniture placement, and color contrast, the space became intuitive and calming for individuals with cognitive challenges without sacrificing aesthetics or cost efficiency.
Designing for dementia, Addie argues, “is really just designing well for everyone.” Whether we’re aging, recovering from injury, or managing sensory sensitivities, environments that support diverse abilities enhance dignity and independence.
Shaping Policy Through the FGI
Addie’s influence extends to the Facilities Guidelines Institute (FGI), where she co-chairs the Residential Healthcare and Support Facilities committee. The 2026 edition introduces an expanded focus on mental and behavioral health, as well as clearer guidance for sensory processing challenges.
By distinguishing between environments that must prevent self-harm and those that must reduce sensory overload, the new standards aim to better serve both ends of the care spectrum. “We’ve been collecting the data for years,” she says. “Now we’re codifying it.”
The Future of Healthcare Is Everywhere
Ultimately, Addie believes that healthcare doesn’t begin or end at the hospital door. “If we think about penitentiaries, workplaces, or cities as places to advance health,” she says, “we change how we design everything, from materials to street layouts.”
Her favorite example: a prison memory-care unit that trained inmates as caregivers. The design, rooted in FGI residential standards, not only improved patient outcomes but reduced recidivism among trained inmates by 60%. “When we enable others,” she reflects, “we enable ourselves.”
Addie closes with a reminder that hits home: “If we aren’t actively enabling our future selves, we’re discriminating against ourselves in advance.”
This conversation reveals a simple but profound truth: healthcare design is self-care, scaled up. The future of healing isn’t just clinical, it’s architectural, operational, and deeply human.
