What Home Addition Work Involves
Room additions cover a wide range of projects that include everything from building an attached garage to full second-story additions. At their foundation, room additions mean physically extending your home's current floor plan — either horizontally or vertically. This is distinct from remodeling, which works within the current square footage.
These projects demand a coordinated effort that involves architectural planning, permit acquisition, foundation work, rough construction, electrical, plumbing, insulation, drywall, and flooring and trim. Because room additions require so many interconnected trades, hiring a skilled construction team who can coordinate each phase is essential.
Room additions are ideal for homeowners who have outgrown their current layout but want to keep their current property. They're also a popular choice for homeowners planning to age in place. No matter the size, the process follows a structured set of phases that our team have executed on hundreds of projects.
