About this home

Welcome to the beautiful 840 Hallam Ave N! Nestled at the end of a quiet cul-de-sac, this home offers the perfect blend of privacy, comfort and year-round enjoyment. A recently installed patio rolls out into the spacious backyard, a wooded setting with plenty of lawn space for relaxing and entertaining. The dreamy screened-in porch is the ideal place to unwind at night and listen to the frogs. In the winter, the adjacent pond becomes a favorite spot for skating. Afterward, head into the walkout basement to hop in your own sauna. The home features an open-concept kitchen that flows seamlessly into the main living areas. With 4+ bedrooms and 3 bathrooms, there’s plenty of room for everyone. The home offers three living room spaces, two on the main floor and one downstairs. The house has two garage spaces. In the backyard, the detached garage includes two stalls plus a recently added double office, convenient for working from home, an art studio, or a gaming room. Connected to the house, there is another two-stall garage that provides even more space for cars, storage, or a workshop. In addition to the brand-new office and patio, the house has received several updates in the past few years: a new roof and gutters with guards, an updated bathroom and appliances such as a dryer, dishwasher, and garbage disposal. Located in the outstanding Mahtomedi School District, this property combines a fantastic location with thoughtful updates and inviting spaces both inside and out.
