Coming Soon to Westfield: Boutique Living Along the Monon

A Fresh Vision for Westfield

Something exciting is blooming along the Monon Trail. Onyx+East’s plan for Trillium, a new residential community in Westfield, has officially been approved by the City Council. With 120 homes coming to life just north of 199th Street, Trillium will bring together modern design, open space, and trail-side convenience in one of Hamilton County’s most desirable areas.

Homes Designed With Lifestyle in Mind

Trillium isn’t your typical neighborhood. Every detail has been carefully considered to create homes that embody both style and substance. With prices starting in the high $500,000s and reaching beyond $1 million, the community offers a range of options that suit different stages of life and personal tastes. On the west side, larger lots provide added space and a natural buffer for neighboring homes, while closer to the Monon, the distinctive European-inspired courtyard clusters introduce a design unlike anything else in Indiana. These unique layouts encourage walkability, connection, and a vibrant sense of community. 

Living Connected to the Outdoors

Life at Trillium will naturally flow outdoors. Thoughtfully and heavily landscaped throughout, the community offers more than nine acres of open green space with winding walking paths, welcoming gathering spots, and a charming pocket park. A direct trail connection at 199th Street and a planned bike fix-it station keep the Monon Trail always within reach—perfect for morning runs, weekend rides, or evening walks with friends.

Why Trillium Stands Out

Set across from The Club at Chatham Hills, Trillium adds a new dimension to Westfield’s growth story. City Councilor Victor McCarty summed it up best: this project offers “a really unique type of product that we don’t have already in Westfield.” From the mix of home styles to the emphasis on community green space, Trillium is designed to be as forward-thinking as the residents it will welcome. At our Carmel Design Studio, you will also have the opportunity to personalize your home by selecting finishes, layouts, and details that fit your lifestyle.

Looking Ahead

While Trillium marks our first for-sale community in Westfield, Onyx+East has already introduced distinctive neighborhoods across central Indiana, including Flora in Carmel, Nickel Row in Fishers, and several thriving communities in downtown Indianapolis.

In the months ahead, we’ll be sharing updates as Trillium takes shape. From construction progress to design sneak peeks and behind-the-scenes moments, you’ll get a closer look at how this neighborhood is coming to life. Stay tuned and follow along with us—we’re just getting started, and there’s so much more to come!
