A US residential care provider has secured a key role in a major senior living development in Missouri, marking its second significant project announcement within a year and signalling continued expansion in response to rising demand for personalised elder care.
Harmony Homes has been selected as the exclusive assisted living provider for the newly approved Stonebridge subdivision in O’Fallon, near St. Louis. The community is being developed by Sansone Design Build and will integrate assisted living provision into a wider active adult neighbourhood designed for residents aged 55 and over.
The Stonebridge Commons project aims to create a continuous care environment, allowing residents to remain within the same community as their care needs evolve. By embedding Harmony Homes’ residential assisted living model into the development, the scheme seeks to bridge the gap between independent living and more intensive care, without requiring residents to relocate elsewhere.
The partnership reflects broader trends in senior housing across the United States, where providers are moving away from institutional settings in favour of smaller, community-based residential models.
Harmony Homes’ approach centres on purpose-built houses accommodating a limited number of residents, with an emphasis on higher staffing ratios and tailored support. The company says this structure enables more personalised care while maintaining a domestic environment.
Bob DeClue, founding partner and chief executive of Harmony Homes, said the latest agreement reinforces the company’s strategy and market demand.
“We are thrilled to be part of the Sansone Design Build’s vision for O’Fallon,” said Bob DeClue, Founding Partner and CEO of Harmony Homes. “This project underscores our commitment to redefining what assisted living looks like. We are not just building a facility; we are creating a home where seniors are treated with the dignity, intimacy, and specialized attention they deserve. This second major project in such a short window proves there is a massive demand for this elevated level of care.”
The Stonebridge development is part of Sansone Design Build’s wider plans to create a destination community combining lifestyle and care provision. The developer believes integrating assisted living within an active adult setting will offer residents both independence and long-term security.
EJ Sansone, president of Sansone Design Build, said selecting the right care partner was central to the project’s vision.
“When we conceptualized Stonebridge as a premier 55+ community for the St. Louis region, we knew we needed a senior living partner that mirrored our commitment to quality and community integration,” said Sansone.
“Harmony Homes is a natural partner for this unique development. Their model allows residents to receive high-touch care in a setting that looks and feels like a neighborhood home, which perfectly complements the lifestyle we are building at Stonebridge,” added Sansone.
The announcement builds on Harmony Homes’ earlier flagship scheme, known as 211 Midland, located in Maryland Heights. The 10-acre site includes six custom-designed homes arranged to create a neighbourhood-style setting, which the company describes as a template for future developments.
The company is now pursuing further growth across Missouri and neighbouring states, reflecting demographic shifts and increasing demand for senior housing.
Harmony Homes is currently exploring new opportunities in Kansas City, as well as Springfield and Columbia. In addition, it is assessing expansion into other Midwestern markets and planning a longer-term move into the south-eastern United States.
The expansion strategy comes amid a rapidly ageing population in the US, which is driving sustained investment in residential care, assisted living and retirement communities. Industry analysts have pointed to increasing consumer preference for smaller, home-style environments over traditional large-scale care facilities.
For Harmony Homes, the Stonebridge project represents both a commercial opportunity and a test of its integrated care model within a larger master-planned community.
If successful, the partnership could serve as a blueprint for similar developments elsewhere, combining independent living and assisted care within a single location — a model designed to offer continuity for residents while addressing growing capacity pressures across the senior care sector.
