Custom Home Builder in
Cornelius, NC
Keystone Building Group is a custom home builder serving Cornelius, North Carolina, on the shores of Lake Norman. With over 30 years of building experience, we take on a small number of luxury custom homes each year. If you already have plans, we build them; if you don’t, we connect you with a trusted partner architect and interior designer, so one team guides your home from first sketch to move-in.
How we work
Many of our clients come to us with completed plans and simply need a builder they can trust to bring them to life. If you don’t have plans yet, we connect you with one of our trusted partner architects, and an interior designer if you’d like one, so you have an exceptional team guiding you through design and selections. From design to build, we bring your dream to life.
What it costs and how long it takes
Custom homes in the Lake Norman area generally run about $325 to $400 per square foot, total under roof. We always share this as a range, never a fixed quote, because your site, plan, and selections set the final number. Once your plans are ready, most homes take about 11 to 14 months to build, depending on square footage; if you’re still designing, the architectural design phase typically adds another 4 to 7 months first.
