645 Hamilton Ave

Visible, versatile, and full of potential, this hilltop delightful farmhouse offers more than just a place to live. Designed for flexibility and zoned for both residential and professional use (RO), this 1,350 sq ft home is ideal for entrepreneurs, creatives, or anyone seeking a hybrid live/work setup in the heart of the North Fork. Whether you’re hosting clients, welcoming guests, or setting up your dream home office, the layout adapts to your needs.
The charming tree-lined front entry way opens into a welcoming central hall, featuring two private rooms— one has a working fireplace for added charm and warmth — plus a powder room, and mudroom, and bright enclosed porch for added flexibility—waiting room, wellness space, gallery—you choose. In addition, the back entrance boasts a large deck for relaxing, entertaining, outdoor dining, or gardening, whatever you wish. Storage needs? The full basement has you covered.
Upstairs, a vaulted ceiling and ambient lighting set the tone for a tranquil loft-style suite, complete with a kitchenette, bedroom and full bath, and open living area. It’s perfect for extended stays, rental income, or a creative retreat away from the main floor.
Recent upgrades in the early 2000’s mean you don’t have to compromise: updated electric, dual-zone heat and CAC, a security system, and a modernized septic setup offer peace of mind and long-term value.
And the location? Prime. Close to Love Lane and all that Mattituck has to offer—yet tucked just far enough off the road to feel removed. Smart zoning. Solid updates. Strategic potential. This is your chance to own a property that works as hard as you do.
