What Room Additions Involves
Room additions cover a wide range of projects that include everything from constructing a new bathroom to large-scale family room builds. At their core, room additions mean physically extending your home's footprint — either outward. This is not the same as remodeling, which stays inside the existing walls.
These projects demand a full range of trades that involves architectural planning, permit acquisition, foundation work, rough construction, electrical, plumbing, insulation, drywall, and flooring and trim. Because room additions require so many interconnected trades, working with a skilled construction team who can manage all of it is essential.
Room additions are commonly chosen by homeowners who have outgrown their current layout but aren't ready to move. They're also a popular choice for homeowners planning to age in place. Regardless of the scope, the work follows a well-defined set of stages that we have refined over many years.
