What Home Addition Work Involves

Room additions encompass many different types of construction that span everything from adding a single bedroom to major kitchen expansions. At their core, room additions require adding to your home's existing structure — either horizontally or vertically. This is different than remodeling, which stays inside the existing walls.

These builds demand a full range of trades that combines architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and flooring and trim. Because room additions involve multiple building disciplines, working with a general contractor who can manage all of it is essential.

Room additions are ideal for homeowners who need more room but aren't ready to move. They're often the right move for multigenerational households. No matter the size, the approach follows a well-defined set of stages that our builders have mastered through experience.
