The First Step Into Your Home Deserves to Be Beautiful

Stone doorwells and thresholds serve both functional and aesthetic purposes. They protect entrances from wear, water and weather, while adding lasting character to your property. At Duke Stone, we handcraft doorwells using high-quality stone that complements the building’s style, age and surroundings. Whether you’re restoring a Cornish cottage or completing a new build, we help you make a lasting first impression.
