Millbrook: the Carmel builder bringing 1,200 homes to West Lafayette

The two previous notes established what West Lafayette is and what is arriving on its north side. This one is about the neighborhood being built to receive it, because for most of the people reading this it is the most concrete question of the three: where, exactly, would a family moving here in 2028 live?

Estridge Homes is a Carmel company, founded in 1967, that built its reputation in Hamilton and Boone counties. If you have driven through Westfield in the last decade you have seen its work: Harmony and Midland are Estridge communities, and they are the kind of neighborhoods that get named in listing descriptions years after the builder has left. The firm's model is the master-planned community, a large parcel developed as a whole with amenities and trails designed in from the start, rather than a subdivision of lots sold to whichever builder turns up.

Millbrook is Estridge's first project in Tippecanoe County. Clint Mitchell and Rob McGraw, who run the company, chose to make that first move at a scale Greater Lafayette has rarely seen from a single residential developer.

The site is 328 acres along Millbrook Boulevard in West Lafayette, immediately north of the SK hynix plant site and about ten minutes from Purdue. Ground was broken in April 2026. The plan, as published by the builder and Greater Lafayette Commerce, is 771 single-family homes and 400 to 500 multi-family units including townhomes, built out over roughly ten years. Single-family prices are expected to run from the $400,000s to $1 million. Home sales are expected to begin in fall 2026.

The amenity list is the master-planned pattern: a resort-style pool, pickleball and sports courts, playgrounds and dog parks, miles of trails, water views, and what the builder calls shared programming, meaning organized community events rather than a clubhouse that sits empty. Mitchell has described the intent as a place people can live in at every stage of life, and the home collections are built around that idea.

In August 2026 Estridge published the first three home collections for Millbrook.

Heritage is the family collection: ranch and two-story plans with three to five bedrooms, three-car garages, and an unfinished lower level included. This is the product aimed at the relocating engineer with children and a school district to think about.

Kingston is spacious ranch living: two to four bedrooms, single-level plans with deliberate outdoor living space and an optional lower level. This is the collection for the buyer who wants room without stairs.

Pierce is the low-maintenance collection: two to four bedrooms, covered outdoor living, optional lower level, and the yard and exterior handled. This is the product for the long-time West Lafayette owner who wants to stay in town, near the campus and the people they know, but is finished with a large house on a large lot.

That third collection is worth a sentence more, because it addresses a problem the previous notes identified without naming it. West Lafayette's owner-occupied inventory is 4,434 homes with a homeowner vacancy rate under one percent. A large share of those homes are held by long-tenure owners who would sell if there were somewhere in town to go. New single-level, low-maintenance product on the north side is exactly that somewhere, and every such move releases an established home into a market that has almost none for sale. The collection is small in the plan, but its effect on the resale market may be out of proportion to its size.

A few things a buyer or seller should hold onto.

The numbers are large and the calendar is long. Seventeen percent more owner-occupied homes is the ten-year figure. Phases release over time, and the first residents will move in while most of the plan is still a drawing. Anyone timing a purchase against the 2028 and 2029 hiring window at the plant should assume that the established neighborhoods, not Millbrook, will carry most of that demand.

The price band is the top of the local market. The $400,000 entry point is above the current West Lafayette median sale price of $364,500, and the upper end has few resale comparables in Tippecanoe County at all. That is the point of the project, and it will change what "the West Lafayette market" means in statistics like the ones in the previous notes. It also means that for many buyers the best value in 2027 will still be an established home on the west side, and the honest comparison is worth running.

Build-to-order takes time, and a new community has a sales office that represents the builder. Both are normal. Both are reasons to have someone on your side of the table who knows the resale market it is being compared against.

Estridge did not need West Lafayette. It has decades of work in the fastest-growing suburbs in the state and could have stayed there. That a company with that track record put 328 acres and a ten-year plan into Tippecanoe County, before the plant had broken ground, is a market judgment made with real money. It is the same judgment the previous two notes reached from the Census data: the town inside the college town is a stable, educated, under-supplied place, and it is about to have more people who want to live in it.
