Who is Integra Builders?

Integra Builders is a family-owned luxury custom home builder based in Fishers, Indiana. It was founded in 1989 by Francois Mercho and is led today by his son, Michael Mercho, a Purdue-trained engineer and Certified Green Professional.

What price range do you build?

Our custom homes typically range from about $1.5 million to $5 million+, depending on lot, size, design complexity and finishes. Lot cost is separate from building cost.

Do you build on my lot?

Yes. We build on a client's lot or on available lots, and help evaluate land for buildability, utilities and site costs before purchase.

Which neighborhoods do you build in?

We build across Carmel, Fishers, Westfield, Zionsville, Noblesville and Geist, with homes in places like the Village of WestClay, Canal Place, Barrington Estates, Chatham Hills and Oldfield Hunt Club.

What is the Custom Home Readiness Review?

It is our pre-construction process that checks your budget, lot conditions and design goals before you commit money to a build, so there are no surprise costs later.

How long have you been building?

Since 1989 — more than 35 years and 350+ custom homes across Central Indiana.

Where a covenant, guideline, or committee interpretation conflicts with the recorded plat depiction, the proponent of the different rule must identify a recorded basis that changes the plat-defined constraint. • The cases below address situations where a recorded plat depiction is treated as the controlling baseline for setbacks, building lines, easements, or related property interests.
