Additions, Permits & Engineering in Castle Pines
A room addition is full structural work — foundation, framing, and often mechanical, electrical, and plumbing — so it requires permits, engineering, and multiple inspections through the City of Castle Pines / Douglas County. Because Douglas County’s expansive bentonite soils heave and shift, a geotechnical report often calls for drilled piers rather than standard footings. We manage the whole process, from the soils report to the final inspection.
Building Your Room Addition in Castle Pines
We build across The Village at Castle Pines, Castle Pines North, and BlackStone and handle the whole project with our own crew: a free on-site consultation, design and material selection, permitting and engineering, construction, and final inspection. Most Castle Pines communities add architectural review before the permit — we build to your HOA’s design guidelines and provide the drawings your submission needs, so approval isn’t a bottleneck.
