What This Type of Project Involves
Room additions encompass many different types of construction that include everything from adding a single bedroom to full second-story additions. At their foundation, room additions require adding to your home's current floor plan — either horizontally or vertically. This is different than remodeling, which works within the current square footage.
These projects require a collaborative approach that brings together architectural planning, permit acquisition, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and final finishes.

Room additions are a great fit for homeowners who want a dedicated space but prefer to stay in place. They're frequently selected for families welcoming new members. Regardless of the scope, the work follows a structured set of stages that our team have executed on hundreds of projects.
