What Home Addition Work Involves
Room additions cover a wide range of projects that span everything from adding a single bedroom to full second-story additions. At their core, room additions mean physically extending your home's current floor plan — either horizontally or vertically. This is different than remodeling, which stays inside the existing walls.
These builds call for a full range of trades that involves architectural planning, permit acquisition, foundation work, structural carpentry, electrical, plumbing, insulation, wall systems, and cosmetic detailing. Because room additions touch so many systems, working with a general contractor who can oversee every step is essential.
Room additions are commonly chosen by homeowners who need more room but aren't ready to move. They're also a popular choice for multigenerational households. No matter the size, the process follows a structured set of stages that our team have refined over many years.
