Cambridgeport - An exceptional 1886 Greek Revival corner row house with four bedrooms plus a separate-entry garden-level studio apartment, where historic character meets highly considered, architect-led design. Lovingly cared for and maintained for decades, the home was completely renovated by its award-winning Cambridge owner-architect with extraordinary attention to craft, material and detail. Original stairs and antique pine floors set the tone. At its heart, a bespoke kitchen channels the warmth of an English country house, with custom cabinetry and shelving, integrated counter-height refrigeration, built-in banquette and distinctive lightingan inviting place to gather, cook and linger, naturally connected to the garden beyond. Four bedrooms and beautifully conceived baths feature floor-to-ceiling tile, custom vanities, stone and elevated fixtures. Throughout, layered lighting creates warmth and atmosphere, while the home's east-west orientation brings changing natural light through the day and seasons. In back, mature River Birches form a leafy canopy over the private garden and patio, an unexpected urban sanctuary. Far from an afterthought, the charming, fully appointed garden-level studiowith its own kitchen and bathoffers remarkable flexibility as a guest or au pair suite, pied--terre, home office or independent living space, with a rental history of over $2,500/month. The attic presents an opportunity for expansion if needed. A singular Cambridgeport home: historic yet fresh, sophisticated yet wonderfully livable, in one of Cambridge's most beloved and walkable neighborhoods.
