About this home

The elegantly restored Calmore Estate, on 2+ beautifully landscaped, stonewalled acres, an expanded 1812 federal colonial graced by classic verandas, 6-bay detached garage, post & beam barn with attached Hartley Botanic greenhouse & perfectly managed organic gardens & orchards. With an authentically renovated country kitchen featured in Early Homes Magazine, a spacious dining room, 2-story screened porch, 1st floor accessory apartment w/handicapped accessible bath & 8 bedrooms--5 of which have ensuite full baths--the large manor house is ideal for gracious entertaining on a grand scale, while offering intriguing possibilities for income as a B&B, retreat, or family compound with inlaw quarters. The heated barn with radiant-heated floors is currently used as an antique boutique; it may be able to continue in a similar capacity by special permit. Updates include recent septic system, whole house generator, underground utilities & FIOS. 25 minutes to Manchester airport, 45 min to Boston.
