The coffee shop. The park. The library. These so-called third places — neither home nor work — may be the most essential and least recognized infrastructure of a connected social life. Dr. Richard Kyte joins Erin to examine what we lose when third places disappear, and what genuine human connection actually requires from the spaces around us.

Sustainability conversations tend to focus on carbon. But what about the social cost of how we build cities? Urban designer Nico Larco joins Erin to explore how the design of our streets, suburbs, and cities shapes our capacity for connection — and what truly sustainable urban design looks like when social health is part of the equation.

We tend to think of social connection as something we pursue — calls we make, plans we schedule, effort we invest. But sociologist Mario Small's research reveals something more surprising: the connections that matter most often happen by accident, shaped by where we are and who we happen to run into. The built environment isn't just the backdrop to social life. It's one of its primary determinants.

Can a street make you more likely to trust your neighbor? Can public space design foster romance, civic participation, or basic human warmth? Urban planner Mitchell Reardon joins Erin to explore the surprising science of happy cities — and why the design of our public realm is one of the most underestimated levers we have for social health.

Why do some spaces make you want to stay while others make you want to disappear? The answer often comes down to one overlooked design principle: choice. In this episode, Erin explores how variety, flexibility, and control over our environment shape our willingness to connect — with real examples from offices, cafes, and healthcare spaces.

Her research established that loneliness carries health risks equivalent to smoking fifteen cigarettes a day. Now Dr. Julianne Holt-Lunstad — one of the world's leading scientists on social connection — joins Erin to explore how the built environment shapes our social lives, and why fighting loneliness requires looking beyond the personal to the places we inhabit.

We evolved in spaces sized to the human body — spaces where we could see across a room, hear a conversation, sense the presence of others without being overwhelmed. When architecture forgets human scale, the body notices. In this episode, Erin explores how designing at human scale creates the conditions for comfort, safety, and social connection — with a real-world example from UC San Diego.

Small changes in how a space is arranged can measurably shift how much we want to connect with the people in it. In the second half of their conversation, environmental psychologist Colin Ellard shares the surprising research on what actually makes us happy in our home environments — and what it would take to design spaces that support our social lives rather than quietly undermine them.

What can evolutionary psychology teach us about the spaces where human connection actually happens? Environmental psychologist and author Colin Ellard joins Erin in this first of two episodes to explore how our ancient social instincts shape what we need from the places we gather — and how COVID-19 revealed just how much those needs had been designed away.

Three in five working Americans report feeling lonely. Most of us look inward for the cause. But what if the design of our cities — the streets we can't walk, the stores that closed, the parks that were never built — is one of the least-examined contributors to that loneliness? This episode explores the built environment's role in the loneliness epidemic.

Why does the design of a room affect whether people connect inside it? How do our streets, schools, workplaces, and neighborhoods shape our social lives — often without our awareness? In this introduction to Shared Space, Erin Peavey lays out the case for why architecture and design are among the most powerful and least-discussed levers we have for addressing loneliness and building social health.
