Gloucester home additions that look like they belong

Across Annisquam, Lanesville, Magnolia, East Gloucester, West Gloucester, Bay View, Riverdale and Rocky Neck, Gloucester ranges from a dense harbor core to outlying Cape Ann villages of 18th- and 19th-century maritime cottages and waterfront homes. A Gloucester addition has to match the roofline, siding and structure of the existing home, so it reads as part of the house, not a box bolted on.

• Clear estimate conversations before the project starts.
• Direct communication with the homeowner from walkthrough to final walkthrough.
• Local coverage across Gloucester and the wider Essex County area.

• Whether it is a ground-level or second-story build.
• Rooflines, siding and how the exterior ties into the existing home.
• Interior finishes, plumbing and electrical the new space needs.
