Welcome to this stunning all-brick custom home in the prestigious gated community of the Boulder Ridge Country Club Estates. You will be impressed with the completion of an outstanding 2025 project which included a brand new cedar roof, four new skylights, copper flashing, gutters and downspouts all totaling over $150,000. Receipts and warranty will transfer to the new owner. This 5-bedroom, 3-bathroom home offers over 3,400 sq ft of luxury living. The freshly painted main floor features a dramatic two-story foyer with a wrought iron staircase, crown molding, and abundant natural light. The spacious kitchen includes granite countertops, stainless steel appliances, and a large center island, opening to a bright four-season sunroom with three patio sliders. Step outside to a professionally landscaped yard with a full brick patio, built-in fire pit, grilling station, raised flower beds, and an irrigation system. A convenient main-floor bedroom and full bath are ideal for guests or in-laws. The vaulted master suite offers large windows and a spa-like bathroom with heated floors, dual vanities, granite counters, a soaking tub, and an oversized custom shower. Upstairs includes three more generously sized bedrooms and an updated full bathroom connected by a catwalk overlooking the family room. The updated laundry room leads to a heated 3-car garage with finished walls and a painted floor. This home also features a brand new A/C system and a new 75-gallon water heater for added comfort. A radon mitigation system is already installed for peace of mind.
