Home Additions & ADUs in Castle Pines, CO

Castle Pines Home Addition Experts

JBHI designs and builds home additions and ADUs for homeowners across Castle Pines and the surrounding South Denver metro. From single-room expansions and pop-tops to garage conversions and multi-generational suites, one team manages design, trades, permitting, and construction from start to finish.

Castle Pines homes from the late 1990s and early 2000s often sit on generous lots with solid structures, while interior layouts have not kept pace with how households live now. Homeowners stay for the schools and setting, then need a larger primary suite, an expanded kitchen, or a separate suite for family. JBHI plans additions that respect lot lines and exterior character so the new square footage reads as original to the house.
