Four Season Room Addition

Nashua, NH

A new four season room addition built off the back of this colonial. We framed and sheathed the bump-out on new pressure-treated posts, wrapped it in matching gray vinyl siding with white trim, and finished the interior with a vaulted ceiling, skylight, recessed lighting, and wide-plank hardwood flooring — turning unused backyard space into a bright, year-round living room.
