What This Type of Project Entails
Room additions cover a wide range of projects that include everything from adding a single bedroom to large-scale family room builds. At their foundation, room additions involve expanding your home's footprint — either horizontally or vertically. This is different than remodeling, which stays inside the existing walls.
These projects call for a collaborative approach that involves architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions require so many interconnected trades, working with a general contractor who can oversee every step is essential.
Room additions are ideal for homeowners who have outgrown their current layout but aren't ready to move. They're frequently selected for homeowners planning to age in place. Regardless of the scope, the process follows a well-defined set of steps that we have refined over many years.
