Keystone Builders is a family-owned custom home builder. For nearly four decades we've crafted refined, enduring homes — with honest communication and uncompromising quality in every detail.






A ground-up custom residence set on twelve wooded acres, the Hollowbrook Estate pairs timber-frame craftsmanship with quiet, modern luxury. Keystone managed the full build — from foundation to final finish — over eighteen months, with the family involved at every milestone, delivering a home made to be passed down for generations.
