What This Type of Project Entails
Room additions are a broad category that involve everything from adding a single bedroom to large-scale family room builds. At their core, room additions require adding to your home's current floor plan — either horizontally or vertically. This is distinct from remodeling, which works within the original layout.

Because room additions require so many interconnected trades, hiring a skilled construction team who can coordinate each phase is critical.
Room additions are a great fit for homeowners who want a dedicated space but want to keep their current property. They're often the right move for homeowners planning to age in place. No matter the size, the process follows a well-defined set of stages that our team have executed on hundreds of projects.
