Additions
Additions that belong to the home
An addition brings together the homeowner, engineers, architects, building departments, and every trade on site. Riverstone coordinates all of it, from preconstruction through construction, so the finished space feels original to the home.

How an addition moves forward
Site Evaluation
We review measurements, access, and constructability alongside your goals for the new space.
Preconstruction
We work out scope, budgeting, permitting, and any architectural or engineering input the project requires.
Construction
We manage foundation work, framing, mechanical trades, and finishes through inspection and closeout.
Project Types
