12 Saint Paul St

A low-rise, early-20th-century two-story residential building in Cambridge offering primarily two-bedroom units. Built in 1903, the property retains period details—original wood moldings, fireplaces with marble surrounds, and higher-than-average ceilings—while many units have been renovated with contemporary finishes such as granite or marble counters, stainless steel appliances, and recessed lighting. Unit types include duplex/penthouse configurations and single-level flats; several residences feature lofted spaces, skylights, and mezzanine offices. Interior common characteristics include custom built closets and cabinetry, half and full bathrooms, wet bars in some units, and in-unit laundry where updated. Exterior amenities emphasize private outdoor living: individual front porches or decks, shared side patios for grilling, and small yard areas; many units report parking access on a private way with room for multiple cars. The building’s maintenance history shows periodic upgrades (roof work, new windows, updated mechanicals) and deleading efforts in the 2000s. Its placement on a quiet private way near Central Square gives residents quick pedestrian access to transit, groceries, restaurants, and MIT, while preserving a more residential, neighborly street experience. Pet policies and formal concierge services vary by ownership; most common-area spaces remain modest and residential rather than amenity-focused.
