What Home Addition Work Involves
Room additions cover a wide range of projects that include everything from adding a single bedroom to major kitchen expansions. At their foundation, room additions require adding to your home's existing structure — either upward. This is not the same as remodeling, which works within the original layout.
These projects call for a coordinated effort that combines architectural planning, building permits, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and flooring and trim. Because room additions involve multiple building disciplines, working with a skilled construction team who can coordinate each phase is critical.
Room additions are commonly chosen by homeowners who want a dedicated space but aren't ready to move. They're also a popular choice for homeowners planning to age in place. No matter the size, the approach follows a well-defined set of stages that our team have mastered through experience.
