A Strawberry Field, Until Recently
Strawberry Farms sits on Mexico Road just down from Highway K, on land that was a working strawberry field. McKelvey kept the name, and the plan is 76 homes in two phases.
McKelvey held the grand opening in October 2025. Phase 1 is 40 lots across the eastern half of the neighborhood; Phase 2 adds 36 more toward the back. The builder describes the community as honoring the Lash family farm, and there are berry patches written into the landscaping plan.
What you are buying into today is early. The first houses are up and occupied, the streets are in, and a good deal of the site is still open ground. That is worth seeing rather than being told, which is why the photographs on this page all carry the month they were taken.

What It Actually Costs
Five floor plans, all from McKelvey's Liberty Series. The base price is the number on the sign. The last column is the number McKelvey themselves have listed the same plan for once it is built and finished.
| Plan | Size | Base price | Built and finished here |
|---|---|---|---|
| FranklinRanch · 3 bed, 2 bath | 1,669 sq ft | From the high $400sThe entry point here | One listed finished in the low $600s |

Base prices and finished-home listings read from McKelvey's own community page in September 2026. Builder pricing moves; ask us for the current numbers.
Budget 25% to 50% above base
This is the rule we give every client, and McKelvey's own inventory proves it without anyone having to argue. The Franklin bases in the high $400s. McKelvey listed a finished Franklin here in the low $600s. Same plan, same community, and that is a house somebody else specified.
Go further and the numbers go further. If you want to go all out on upgrades, expect to spend somewhere between $700,000 and $900,000. But that is a choice, not a toll: staying close to base is genuinely an option here, and plenty of buyers take it.
Spend on structure first, cosmetics later. Taller ceilings, a garage bump-out, an extra bedroom or bathroom, lower level rough-ins, a deeper pour. Those are the things you cannot add afterwards without tearing something apart. Countertops, flooring, cabinets and light fixtures can wait until after you move in, and they are where a budget gets rescued when the design studio total climbs.
We will call McKelvey and find out what is genuinely open, tell you which plans fit which lots, and flag the upgrades worth paying for before you sit down in the design studio.
Want to Know What Is Still Available?
How the Lots Differ
Lot type decides what your lower level is worth, and it varies across this site. Ask us what is genuinely available this week.
In-grade, walk-out, look-out
All three exist here, and the difference decides what your lower level is worth. An in-grade lot sits level and the basement is fully underground. A walk-out opens onto the back yard at lower-level height. A look-out is the middle case: high windows, real daylight, no door.
Phase 1 is heavily in-grade. Phase 2 comes closer to an even split. Homes come with unfinished basements as standard and finishing one is an upgrade, so if you are counting that square footage as part of the house, the lot you choose matters as much as the plan you choose.
What Is Going In
Modest and specific, which is the right size for a 76-home neighborhood.
A lake with a fountain
The centrepiece of the common ground, on the western side away from Mexico Road.
A gazebo
The neighborhood gathering point, and the thing that turns common ground into a place people actually stand around in.
A playground
Within the subdivision.
Walking trails
Connecting through the subdivision rather than stopping at a property line, which is the difference between a trail and a path.
These are on the plan and being built as the phases go in. We have not toured a finished lake or a finished trail yet, and we will say so on this page when we have.
What It Looked Like, and What It Looks Like Now
Five months apart, from the same drone. This is the fastest honest answer to how far along it is.
We Work For You.Not the Builder.
The person in the sales trailer is employed by McKelvey Homes and represents McKelvey Homes. That is not a criticism. It is the job, and they are good at it.
We represent you. We have worked with McKelvey for years, we know the Liberty Series, and we know which of its upgrades earn their money back and which of them do not. It costs you nothing to bring us, and the one rule is that we have to be with you on your first visit.
We go through this in more detail in our article on whether you need a realtor when buying new construction.
We read the lot before you love the plan
Grade, orientation, what it backs onto and what that does to the lower level.
We are in the design studio with you
That is where the number climbs. Structure first, cosmetics after move-in.
We know what the contract actually says
Builder contracts are written by the builder. Someone should be reading yours for you.
We will tell you when it is the wrong community
If the house you want will not work on what is open here, we would rather say so before the design studio than after.

Where It Puts You
O'Fallon is the largest suburb in the St. Louis metro, and this corner of it is set up for errands.
Highway K is the north-south commercial spine of O'Fallon and it is close. Coffee, groceries, gyms, restaurants, the cinema, the errands you do without thinking about them. Drake's, Gioia's Deli, Rosalita's Cantina and 7 Brew are all within a few minutes.
Interstate 70 is about four minutes away, which is the number that actually matters if you commute. From there it is a straightforward run across St. Charles County, out to the airport, or into the city in something like 35 minutes outside the worst of the traffic.
Schools are Fort Zumwalt R-II: Progress South Elementary, Fort Zumwalt South Middle and Fort Zumwalt South High. Boundaries belong to the district and the district can move them, so confirm before you buy on the strength of one building.
Questions Buyers Ask Us
How much does a home at Strawberry Farms cost?
Base prices for the five Liberty Series plans run from the high $400s to the high $500s, read off McKelvey's own plan pages in September 2026. That is not what anyone pays. Our rule is to budget 25% to 50% above base for the upgrades you will actually want, and McKelvey's own finished homes here bear it out: they have listed inventory homes from the low $600s into the low $680s. Ask us for this week's numbers before you budget against any of this.
So will I really spend $700,000 to $900,000?
Only if you want to. That figure is the all-out case, and we are explicit about the other option: if you want to stay close to the base price, you can absolutely do that. The way to land where you meant to is to decide early which upgrades are structural and which are cosmetic, because that decision is what moves the number.
What is the difference between an in-grade, walk-out and look-out lot?
An in-grade lot sits level, so the basement is fully below ground. A walk-out lets you open a door from the lower level straight into the back yard. A look-out sits between the two: windows high on the lower-level wall, daylight but no door. Phase 1 here is heavily in-grade. Phase 2 is closer to an even split between in-grade and walk-out. If you plan to finish the basement, this is the decision that determines whether that space feels like a floor of the house or like a basement.
Can I get a three-car garage?
Not on most homesites here. A three-car garage is not possible on the majority of lots in this community, so ask before you pick a plan rather than after. It is an easy constraint to discover too late, once you are already attached to a floor plan that will not fit the lot you wanted.
Which lots back onto Mexico Road?
Some of them do, along the southern edge, and that is worth knowing before you choose. Others back to trees and common ground on the western side, and most back to other homes in the community or to the existing homes in Aspen Pointe next door. None of that is a defect, but a road-facing back yard and a tree-lined one are different products at similar prices, so walk the lot before you sign for it.
How long does it take to build?
Six to nine months from breaking ground, depending on weather, materials and trades. Your closing date is a moving target when you build new. If a date is fixed for you, because a lease ends or a sale closes, say so early and look hard at the inventory homes instead.
Are there move-in ready homes?
Usually. McKelvey builds inventory homes here and had several listed in September 2026, some with real price reductions attached. They are the way to skip most of the wait, and the trade is that the finishes are already chosen. We can tell you which of the current ones are genuinely well specified and which are priced as though they are.
What schools serve Strawberry Farms?
Fort Zumwalt R-II. Students are zoned for Progress South Elementary, Fort Zumwalt South Middle and Fort Zumwalt South High School. Attendance boundaries are the district’s to change, so confirm with Fort Zumwalt before you buy on the strength of a specific building.
Do I need my own agent if I am buying from McKelvey?
The agent in the sales trailer is paid by McKelvey and represents McKelvey. That is not a criticism, it is their job. Ours is to represent you: comparing lots, reading the contract, telling you which upgrades hold their value and which do not, and being in the room at the design studio when the number starts climbing. It costs you nothing to bring us, and we have to be with you on your first visit.
