Keystone Construction was founded in 2015 by third-generation builder Merle Sauvola with a simple goal: build high-quality homes with a process that actually works.

Based in Greer, South Carolina, we specialize in building on your lot throughout the Upstate—helping clients turn their land into a finished home without the confusion, delays, and guesswork that often come with custom construction.

Over the years, we’ve built everything from efficient starter homes to fully custom lakefront properties. But what sets us apart isn’t just the homes—it’s how we build them.

We’ve developed a structured, proven process that prioritizes planning upfront. Most selections are finalized before construction begins, which allows us to stay on schedule, control costs, and deliver a smoother experience from start to finish.

We believe building a home should feel exciting—not overwhelming. That’s why we focus on clear communication, realistic expectations, and doing what we say we’re going to do.

For us, every project is more than a house—it’s a long-term relationship. Many of our clients come back to build again or refer friends and family, and that’s something we don’t take lightly.

If you already own land—or you’re planning to buy—we’re here to help you build it the right way.
