What This Type of Project Entails
Room additions encompass many different types of construction that involve everything from adding a single bedroom to full second-story additions. At their heart, room additions mean physically extending your home's current floor plan — either upward. This is different than remodeling, which works within the original layout.
These projects require a coordinated effort that brings together architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and final finishes. Because room additions require so many interconnected trades, choosing a general contractor who can manage all of it is the key to a smooth project.
Room additions are commonly chosen by homeowners who have outgrown their current layout but want to keep their current property. They're frequently selected for homeowners planning to age in place. No matter the size, the process follows a structured set of stages that our builders have executed on hundreds of projects.
