Commonwealth Avenue

Boston, MA

Luxury Renovation

Architect: Grassi Design Group

Project size: 15,000 SF
Construction Duration: 14 months

Connaughton Construction renovated the four story, 15,000 SF former French Consulate in Boston’s historic Back Bay into five, customized, luxury condominiums including a penthouse that featured a curved stairway with wrought iron railings and a figured mahogany library.

A separate carriage house was connected to the main building with an enclosed walkway. The lower level was retrofitted into a six-bay parking garage; the upper level renovated into a guest suite for the first floor (unite 3); and the garden level divided into two au-pair, guest suites.

The main house’s original ornate moldings, mahogany panels and marble flooring on the first floor were retained ad restored. The units bathrooms were fitted with limestone, marble and imported tile; remote control gas fireplaces were added to some rooms while wood-burning fireplaces in others were relined; and all were fitted with high speed internet cable, custom audio, stereo and telephone systems. Hardwood floors were quarter-sawn oak, cherry and walnut. Many cabinets were customized using different woods.

Special care and attention to detail was given while installing all the mechanical (HVAC, plumbing, electrical, sprinkler) systems to retain the building’s elegant finishes. The brownstone and brick facade was restored, windows replaced, and roof decks, terraces and balconies were added.
