A family business, built on relationships.
Why it’s called Cornerstone.
In ancient building, the cornerstone was the first stone set. Every wall was squared to it, and every other stone took its line from it. Scripture uses that picture for Jesus: the stone the builders rejected, made the chief cornerstone.
“The stone that the builders rejected has become the cornerstone.” Psalm 118:22
Mark and Tracy named the company for Him. Their marriage, their family and their business are built on Christ first, and they want every home they build to carry that same honesty: square, true, and made to last.
Mark started pursuing a degree in architecture at Kent State University. To pay for school, he began working for a builder and fell in love with the building process. He considered dropping out to build, but decided to finish and earned a B.A. in Interior Design. He has been designing and building ever since.

From a full team to a hand-picked circle.
Cornerstone once ran a full in-house team. Today Mark works with a small circle of highly vetted contract partners, people whose work he knows and trusts. It means fewer hand-offs, and that Mark himself stays close to every decision on your home.
“I am always on the lookout for partners that have high quality standards at a reasonable price, and that stand behind their work for the long haul.”Mark Gilliland, Founder
The details they’d build for you.
Taking advantage of Colorado’s beautiful weather often means building some outdoor living environments.
Building it, start to finish.
Every Cornerstone home: on site, every stage.
Built on Christ.
The reason for the name. Honest numbers, honest timelines, and a handshake that means something.
We build homes for families.
Because we know what a home is for: holidays, homework, and the people who come back to it.
Known by name, for years.
Mark still picks up when a family he built for calls, years after move-in. That’s the measure he cares about.
