Keystone Custom Homes

About

Keystone Custom Homes works from an office on Granite Run Drive in Lancaster and builds in Pennsylvania, Maryland, North Carolina and South Carolina, with Virginia added on its website. It calls itself Central Pennsylvania's largest independent homebuilder and says Builder Magazine has honored it three times. Buyers can choose a floor plan, build on their own lot, or work through a design studio, and financing is offered. Reviewers talk about the floor plans, the room to customize, the model homes and the company's own app.
