Regency at Montaine

Regency at Montaine is a luxury 55+ active-adult community by Toll Brothers in Castle Rock, Colorado, tucked into the foothills of the Rocky Mountains along the eastern edge of the Front Range. Positioned within the larger Montaine master-planned development — which also includes an all-ages neighborhood — Regency is the age-restricted enclave, planned for 130 single-family ranch-style homes across three distinct collections named for nearby Colorado counties: Jefferson, Broomfield, and Boulder. Construction began in 2020 and the community is still actively building, with quick move-in homes alongside fully personalized to-be-built options. The three collections span a wide range of sizes and price points. The Jefferson Collection offers the most approachable footprint, with four ranch floor plans from roughly 1,600 to 2,065 square feet and base pricing from the upper $640,000s. The Broomfield Collection steps up to 2,000-2,400 square feet with four plans starting in the mid $740,000s. At the top, the Boulder Collection delivers grand single-level designs from about 2,500 to 3,090 square feet with base prices starting in the mid $840,000s — final sale prices routinely push well past $900,000 once lot premiums and design-studio upgrades are included. All homes are single-level with main-floor primary suites, wide halls, open kitchens with large islands, covered patios, and two-to-four-car garages, and Toll Brothers' design studio gives buyers hundreds of finish options. Life here revolves around an exclusive residents-only clubhouse and amenity center with panoramic views toward the foothills. The amenity package includes a lap and lounge pool, spa, outdoor patio, state-of-the-art fitness center, multi-purpose and meeting rooms for clubs and classes, and outdoor courts for pickleball, bocce ball, and tennis. A full-time on-site activities director programs the social calendar — book clubs, fitness classes, volunteer groups, walking and jogging groups, and seasonal events — which gives a brand-new community more social traction than it would otherwise have in its early years. The real differentiator is the land. The greater Montaine master plan preserves 548 acres of open space and 13 miles of hiking and biking trails right on-site, with Mount Montaine — the highest point in Castle Rock — anchoring the property. Residents get sweeping views of the Rocky Mountains to the west and the Great Plains to the east, dark night skies, and mature ponderosa pines throughout. The HOA handles lawn care, snow removal, landscaping, and upkeep of the pools and clubhouse, which keeps daily maintenance low and makes lock-and-leave travel easy — a meaningful perk given how many residents split time between Colorado and warmer-weather second homes. The location is a major draw. Regency sits just off I-25 at the Plum Creek Parkway exit, less than 10 minutes from Old Town Castle Rock's restaurants, Outlets at Castle Rock shopping, and Castle Rock Adventist Hospital. Denver is roughly 33 miles and 40 minutes north; Denver International Airport is about 45 minutes; Colorado Springs is about 35 minutes south; and the Denver Tech Center sits roughly 25 minutes up I-25. The overall feel is upscale mountain-adjacent suburban — quiet, amenity-rich, and unmistakably Colorado, with an emphasis on luxury single-level living for buyers who want to stay active outdoors without giving up resort-style comforts.
