Maybe you love the idea of a brand-new home, but you keep coming back to one question: who actually built it, and will they still be around after you move in?
When I walk buyers through 237 Markus Glen, they notice the finishes first. What I like to talk about is the team that put them there, because that is the part of a new home you live with for years.
Clean trim lines and a wood handrail on the stairs to the upper bedrooms.
A Southwest Michigan builder since 1992
Cornerstone Construction & Builders was established in 1992 and is based in Richland, just down the road from Lake Doster. They build mainly in Allegan, Barry, Calhoun, Eaton and Kalamazoo counties, and new homes are their main business.
Founder and president Rich Rosenberger puts it simply: "Our goal is to make our client's build simple and easy." Today the company is in its second generation, with Rich's son Owen working alongside him and a team that shares the same standards. You can see more of their homes on my Cornerstone Construction page.
The work starts with the first bucket of earth
Many builders hire out excavation completely. Cornerstone does its own excavation and foundations, and their concrete foreman has been in the business for well over 30 years. The people responsible for building the home are the same people making sure it starts right.
That approach carries through the rest of the build. Cornerstone works with many of the same skilled subcontractors year after year. They know each other, they know what Cornerstone expects, and it shows in the finished home.
Details you notice after you move in
Some of the best design choices at 237 Markus Glen are easy to miss on a quick showing and obvious after a few months of living there. The kitchen has white cabinetry with black hardware, a tile backsplash and a walk-in pantry placed so groceries and small appliances stay close without crowding the counters. The oversized island becomes the spot for quick meals and conversation.
By the garage entrance, the laundry area and built-in coat bench catch coats, shoes and bags before they reach the kitchen. The three-car garage has extra width along the walls and a rear bump-out for bikes, tools and lawn equipment. Even the staircase, with its wood handrail and clean trim lines, shows the care that went into the finish work. I wrote more about the kitchen in Hosting at Lake Doster: The Kitchen at 237 Markus Glen Drive.
A builder who stays in the picture
Even though this home was built before its owner was known, Cornerstone handles the final walkthrough much like they would for a custom home. You walk the home, ask questions, point out punch-list items and learn the home's systems before closing. After you move in, Cornerstone provides warranty support and comes back for a one-year walkthrough. I laid out each step in Buy New With Confidence at 237 Markus Glen in Lake Doster.
Room to make it yours
The walkout lower level is unfinished and already plumbed for a future full bath, so you have space to grow into. If you would like to explore finishing it, Cornerstone is willing to talk about that as part of your purchase.
A first year at Markus Glen
Picture it. Your first fall, you're on the deck watching golfers come up the 17th fairway. Your first winter, the coats and boots land on the mudroom bench instead of the kitchen floor. And when the one-year mark comes around, the builder who dug your foundation is back at your door for the walkthrough.
