Harmony's housing stock is overwhelmingly newer construction, reflecting its development beginning in the early 2000s and its ongoing expansion. The community is composed of several residential neighborhoods and villages built by different builders over time, offering a range of single-family floor plans and architectural styles within a consistent New Urbanist framework. The Lakes at Harmony, a 55+ active adult section by Lennar, adds resort-style amenities and championship golf for older buyers. Because the development is still growing toward its approved capacity, the market is characterized by relatively recent homes, modern layouts, and a master-planned, amenity-rich environment rather than historic or established resale stock.

Harmony is organized as a traditional neighborhood development, with residential villages arranged around the town square, the two natural lakes, and the golf course. The central town square serves as the community's gathering place, while neighborhoods radiate outward through a network of streets designed for walkability and connection. The Lakes at Harmony forms a distinct 55+ enclave within the larger community, centered on resort-style amenities and golf. Cat Lake and Buck Lake, together nearly 1,000 acres of natural water, frame much of the community and provide lakeside settings for homes and recreation areas alike.

Harmony is designed around a traditional small-town way of life, with a walkable town square at its center and community events that bring residents together throughout the year. The New Urbanist design philosophy emphasizes front porches, pedestrian-friendly streets, and shared public spaces, fostering a neighborly atmosphere distinct from typical suburban sprawl. Residents enjoy access to parks, walking trails, lakes, golf, playgrounds, and outdoor recreation, while remaining connected to the employment and entertainment of Central Florida. The community appeals especially to families drawn by the combination of open space, recreational amenities, and highly rated schools.

Harmony is served by highly regarded schools that are a major draw for families, with the area's public schools described as A-rated. Harmony Community School serves the community directly, and the broader Osceola County School District provides additional elementary, middle, and high school options. For continuing education, students have access to Valencia College's Osceola campus and the University of Central Florida within the region. The combination of strong local schools and nearby higher-education institutions reinforces Harmony's family-oriented character and its appeal to those relocating to Central Florida.

Harmony sits along the U.S. Route 192 corridor just south of Kissimmee, providing a direct route into the Orlando–Kissimmee region and access to the area's major highways. Its location places residents about 29 miles from the Orlando-area theme parks and roughly 35 miles from the Atlantic beaches near Melbourne, making it convenient for both employment and recreation across Central Florida. As a master-planned community, Harmony is automobile-oriented for regional travel, while its internal street network is designed for walking and bicycling within the neighborhood, reflecting its New Urbanist roots.

Recreation is woven throughout Harmony's design. The Harmony Golf Preserve offers championship golf within the community, while Cat Lake and Buck Lake support fishing, kayaking, and lakefront enjoyment. A network of walking trails, parks, and playgrounds connects the residential villages to the town square and natural areas, encouraging an active, outdoor lifestyle. Community events and the 55+ Lakes at Harmony's resort-style amenities add further recreational options. Combined with the community's large share of preserved open space, Harmony provides residents with ready access to nature and recreation without leaving the neighborhood.
