What Room Additions Entails
Room additions are a broad category that span everything from adding a single bedroom to full second-story additions. At their foundation, room additions mean physically extending your home's current floor plan — either horizontally or vertically. This is distinct from remodeling, which works within the original layout.
These builds require a full range of trades that brings together architectural planning, city approvals, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and final finishes. Because room additions require so many interconnected trades, hiring a experienced builder who can coordinate each phase is the key to a smooth project.
Room additions are commonly chosen by 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 work follows a well-defined set of phases that our builders have executed on hundreds of projects.
