What Home Addition Work Covers
Room additions cover a wide range of projects that span everything from adding a single bedroom to large-scale family room builds. At their foundation, room additions require adding to your home's footprint — either upward. This is not the same as remodeling, which reconfigures the current square footage.
These builds require a full range of trades that combines architectural planning, permit acquisition, foundation work, framing, electrical, plumbing, insulation, interior finishing, and final finishes. Because room additions involve multiple building disciplines, working with a skilled construction team who can coordinate each phase is the key to a smooth project.
Room additions are commonly chosen by homeowners who have outgrown their current layout 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 work follows a structured set of stages that our team have refined over many years.
