Welcome to The Elms, the Henry Harnden House, a remarkable historic Colonial near Silver Lake in Wilmington. This distinctive 7-bedroom, 6-full-bath residence offers 4,220 sq. ft. of above-grade living space and an extraordinary blend of architectural character, modern comfort and flexibility. The owner reports investing approximately $1 million in a comprehensive, multi-year rehabilitation, including extensive electrical and plumbing improvements, updated heating and hot water, multi-zone Carrier heating and cooling, insulation, roofing, approximately 58 replacement windows, exterior restoration, renewed walkways and driveway, and beautifully finished interiors. All 8 fireplaces are operational, and all chimneys have been repointed. The chef-inspired kitchen is a centerpiece, featuring Bertazzoni appliances, a six-burner double-oven range, quartz countertops, dual sinks and generous custom cabinetry. Refinished hardwood floors and period architectural details preserve the home's historic appeal. The expansive layout provides exceptional room for entertaining, home offices, creative pursuits, guests and everyday living. An attached one-bedroom apartment with a separate entrance is currently rented for $1,800 per month, including utilities, adding another dimension of flexibility. Outside, approximately 0.8 acres provide space to enjoy a covered porch, rear patio, landscaping and parking for up to 8 vehicles. Public water and sewer offer added convenience. A walk-up attic and unfinished basement provide additional storage beyond the stated living area. Associated with Civil War cavalry officer Henry Harnden, the property also has a connection to Silver Lake's historic summer resort era. Enjoy Wilmington's commuter rail service, shopping, restaurants and regional access to I-93 and I-95. Imagine gathering around a working fireplace, preparing meals in the beautifully appointed kitchen, welcoming guests onto the porch or simply appreciating the craftsmanship of a home with generations of history. Few properties bring together this scale, restoration, architectural personality and versatility. The Elms is not simply another large house; it is a distinctive piece of Wilmington's past, thoughtfully renewed for its next chapter. Schedule a private tour and experience the setting, space and extraordinary restoration firsthand.
