Sharon Prince, CEO & Founder
Five years ago, we posed a straightforward question: Are our buildings ethically sourced as well as sustainably designed? At the heart of that question was the core belief that every building should honor the dignity of those who harvest, mine, and processes its materials.
Jazz Breakfast · Plenary Panels · Breakout Sessions
Featured Speakers · Announcement of Pilot Projects
Exhibits, Tours, and Pop-ups
Last year’s Summit brought together people across sectors to tackle some of the built environment’s current challenges in addressing forced labor in the building materials supply chain, including U.S. foreign policy, ethical sourcing for data centers, material circularity in construction, the narratives of monuments in underrepresented communities, and ethical decarbonization.
In 2026, Grace Farms announced four new Design for Freedom Pilot Projects, including two international projects and the National Juneteenth Museum. Grace Farms also recognized student leaders who won the 2025 ACSA Design for Freedom Competition for architecture students. More than 550 leaders attended last year’s sold-out Summit, as well as students from 21 colleges and universities nationally.

Speakers

Sharon Prince
CEO & Founder, Grace Farms
Co-Founder, Grace Farms Tea & Coffee
Biography
Sharon Prince is the CEO and Founder of Grace Farms, a new kind of boundary-defying public space that advances good locally and globally. Prince commissioned Pritzker Prize-winning SANAA architects Kazuyo Sejima and Ryue Nishizawa to design Grace Farms, which has become widely known as a global humanitarian and cultural center located in New Canaan, Connecticut.
Grace Farms is the platform for the Foundation and its interdisciplinary humanitarian mission to pursue peace through nature, arts, justice, community, faith, and Design for Freedom, a global new movement to eliminate forced labor from the building materials supply chain. The open, porous architecture of the River building at Grace Farms is embedded into 80 acres of natural biodiverse landscapes. The building, designed to break down barriers between people and sectors, invites all to pause and reflect, while also encouraging engagement with Grace Farms’ work, including advancing gender and racial equity, all of which leads to creating new outcomes.
Since opening, Grace Farms has garnered numerous prestigious awards for contributions to architecture, environmental sustainability, and social good, including the AIA National 2017 Architecture Honor Award and the Mies Crown Hall Americas Prize.
Grace Farms is pioneering a new form of philanthropic capitalism with a non-profit owned certified B Corp. Prince is the Co-Founder of Grace Farms Tea & Coffee, which offers coffees and teas that demonstrate what the Foundation advocates for: ethical and sustainable supply chains. Through our robust corporate-sponsorship program we’ve expanded the reach into global corporations including JPMorganChase, UBS, Sciame Construction, and Bloomberg. In addition, Grace Farms Tea & Coffee has also introduced its Wellness Teas into 26 Whole Foods Markets in 2024 alone, initializing public demand for ethical sourcing.
100% of the profits from Grace Farms Tea & Coffee supports the Design for Freedom movement to eliminate forced labor from the building materials supply chain.
After recognizing a void in addressing exploitation in the building materials supply chain in late 2017, Prince launched Design for Freedom in 2020 with a first-of-its-kind publication, a nearly 100-page Report that provides analysis and data on how forced labor is embedded into the very foundations of our buildings. At the inaugural Design for Freedom Summit in 2022, Grace Farms also released the Design for Freedom Toolkit, a
practical resource professionals use to implement ethical sourcing strategies into their practices. Prince also initiated the next iteration of the Design for Freedom Toolkit to further advance the international expansion of Design for Freedom. The Design for Freedom International Guidance & Toolkit, which includes contributions from more than a dozen leading international experts across the ecosystem of the built environment.
In addition, Prince has also expanded Design for Freedom internationally through accelerators in the UK, India, and Vietnam equipping public and private sector partners with the tools to address forced and child labor.
She has guest lectured about Design for Freedom andGrace Farms to universities and industry associations around the world. In recognition of this impactful work, Fast Company named her to its list of the Most Creative People in Business 2022: For Cleaning up Construction and the AIA NY and Center for Architecture recognized her with the NYC Visionary Award.
At the start of the COVID 19 pandemic, when countries around the world shut down, Prince convertedGrace Farms into a humanitarian hub to address two emerging crises:the lack of PPE for frontline health care workers and soaring food insecurity. Under her leadership, Grace Farms became the largest supplier of PPE in the state, securing, donating, and delivering more than 2 million pieces of PPE within weeks to close the acute state-wide PPE gap. She also initiated a critical food emergency program that provided more than 150,000 wholesome meals to neighbors in need. For this humanitarian work, Prince received the CEO Forum’s Transformative CEO Award | Leading through Crisis.

Jing Liu
Founder
SO-IL
Biography
Jing Liu has been practicing for more than 15 years, working on a wide range of projects both in the US and abroad. Through building practice and interdisciplinary research projects, Liu has led SO–IL in the engagement with the socio-political issues of contemporary cities — in projects like the Artists Loft North Omaha and the Martin Luther King, Jr. Library in Cleveland. Her projects range from artistic collaborations with contemporary choreographers and visual artists to master plans and major public realm design in cities like Melbourne and Indianapolis.
Liu brings an intellectually open, globally aware, and locally sensitive perspective to architecture. Her curiosity and artistic imagination allow her to bring a nuanced cultural perspective to the table. Her keen skills in combining digital technology with traditional craft and firm belief in design’s ability to re-engage people with the physical world around them allow the buildings she designs to become places of exchange that welcome interpretation and transformation.
Liu leads all of her projects from concept to realization and considers carefully all aspects of design and construction — from the building’s presence in a community, down to the fasteners in a window. She believes strongly that design should and can be accessible to all, and that architecture offers us an open platform to nurture new forms of interaction. To that end, Liu sees community engagement and collaboration across disciplines as central to her role as the design lead.

Toshihiro Oki
Architecture Advisor
Grace Farms
Biography
Toshihiro Oki, an architect and active member of the Design for Freedom Working Group, develops and conducts programs and tours that offer unique insights into the architectural choices that informed the River building’s distinct look and award-winning design. As a member of the Working Group, he also provides an informed perspective to not only industry professionals but to the public at large on how buildings, homes, and landscapes can be designed and built with materials less at risk of forced labor.
He established his office in New York after working for several years at the Japanese architectural office of SANAA / Kazuyo Sejima + Ryue Nishizawa (Pritzker Prize 2010) to build the New Museum of Contemporary Art in New York City and the Toledo Museum of Art Glass Pavilion in Ohio. Since 2009, he has been working on his own independent projects. Oki is licensed to practice architecture in New York and has taught architecture studio at Columbia University Graduate School of Architecture and Princeton University Graduate School of Architecture.
Architecture should raise the human imagination beyond the conventional everyday. This requires an unconventional process. The experience of bridging the cultural gap of international teams, clients and locations has led to the focus of thinking globally and acting locally. Every project has a unique set of conditions that requires both an open perspective and a focused process. In order to expand the possibilities, each project team is assembled from a trusted group of associates, engineers and builders based on the project’s specific needs. This creates a dynamic team structure that can efficiently focus on the design and finding its subsequent reality. Such flexible partnerships and conditions help lead to unanticipated paths of new thinking and possibilities
