What This Type of Project Involves
Room additions click here encompass many different types of construction that include everything from building an attached garage to large-scale family room builds. At their foundation, room additions involve expanding your home's current floor plan — either outward. This is different than remodeling, which reconfigures the original layout.
These builds call for a collaborative approach that combines architectural planning, permit acquisition, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions require so many interconnected trades, choosing a general contractor who can coordinate each phase is critical.
Room additions are ideal for homeowners who need more room but want to keep their current property. They're also a popular choice for multigenerational households. No matter the size, the approach follows a clear set of stages that we have executed on hundreds of projects.
