What Room Additions Entails
Room additions encompass many different types of construction that include everything from building an attached garage to full second-story additions. At their foundation, room additions mean physically extending your home's current floor plan — either upward. This is distinct from remodeling, which reconfigures the original layout.
These builds demand a collaborative approach that combines architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, wall systems, and cosmetic detailing. Because room additions require so many interconnected trades, choosing a general contractor who can coordinate each phase is the key to a smooth project.
Room additions are a great fit for homeowners who need more room but want to keep their current property. They're also a popular choice for homeowners planning to age in place. No matter the size, the approach follows a well-defined set of phases that we have refined over many years.
