Onyx+East and IHP Capital Partners Close on Land for Trillium, a New For-Sale Home Community in Westfield

Onyx+East, a full-service homebuilder, and IHP Capital Partners, one of the nation’s leading residential real estate investment firms, announce the closing of 44 acres for the development of Trillium, a new for-sale home community in Westfield, Indiana.

Located at 199th Street and the Monon Trail, Trillium will bring 119 detached single-family homes to one of Hamilton County’s most desirable areas. Groundbreaking and construction are expected to begin in July 2026, with sales launching in spring 2027 alongside four model homes and several quick move-ins.

Trillium is designed to combine modern architecture, flexible living, open space, and trail-side convenience. The community will offer a diverse mix of homesites, from low-maintenance courtyard lots to expansive executive homes, creating options for a variety of buyers and stages of life.

At completion, homes will range from approximately 2,000 to 4,500 square feet of finished living space, each with an additional unfinished basement spanning approximately 1,100 to 2,000 square feet. Homes will feature 10-foot ceilings, flexible floor plans, 3–5 bedrooms, and 2.5–3.5 bathrooms.

Ten courtyard homes will offer direct access to the Monon Trail, Indiana’s award-winning rail trail. The community will also include more than nine acres of landscaped open space, featuring walking paths, gathering areas, and a naturalized playground, along with a direct connection to the Monon Trail at 199th Street.

“Guided by extensive research, the newly designed floor plans reflect a modern approach to living—adaptable, functional, and responsive to a range of lifestyles,” said Kelli Lawrence, CEO of Onyx+East. “Trillium allows us to expand our home offerings for buyers seeking elevated living options while breaking away from traditional suburban development. With unique site plans, distinctive architecture, and direct access to the Monon, the community offers a rare opportunity for thoughtful, design-forward living in Westfield.”

Buyers at Trillium will have the opportunity to personalize their homes at Onyx+East’s local design center, working with experienced designers to select finishes, layouts, and details that reflect their personal style. Smart home technology and thoughtful design features will also be incorporated throughout the homes, appealing to move-up homeowners, young families, downsizers, and buyers seeking a more elevated living experience.

Surrounded on three sides by the established and nearly sold-out Chatham Hills masterplan golf community, Trillium offers a rare location with both neighborhood connection and access to nature. The Monon Trail runs directly along the community’s eastern boundary, providing walkable access to a 20-mile regional recreation corridor. The property is also located near high-performing public schools, upscale detached homes, and major employment centers, with US 31 just one mile east of the site. Downtown Indianapolis is approximately 20 miles south.

While Trillium marks Onyx+East’s first development in Westfield, the community is part of the company’s broader expansion across Hamilton County. Onyx+East is actively selling and constructing at Flora in Carmel, Indiana, a 121-home community set on 37 acres, and Nickel Row in Fishers, Indiana, a 35-unit townhome community located along the Nickel Plate Trail. Onyx+East also continues to grow through thriving communities throughout the greater Indianapolis area.

“We are excited to partner with Onyx+East as we enter the Indianapolis market with the Trillium project,” said Richard Whiteley, co-president at IHP Capital Partners. “Their team brings extensive local market knowledge, a seasoned leadership group with strong construction expertise and a proven ability to deliver high-quality communities on time and on budget. We look forward to working together to bring a thoughtfully designed neighborhood to Westfield while establishing a new long-term partnership in the Midwest.”

Whelan Advisory served as the exclusive financial advisor to Onyx+East.
