Looking for a family-sized home in a premium Eastside CM location? Start with the mid 400 Block of treasured Costa Mesa Street with great exposure on the South side of the street. Add a 4 Bedroom, 3 Bathroom floor plan with a dramatic, open-beamed Family Room with Fireplace added to the rear. The floor plan also features a spacious formal Living Room with the original Wood Burning Fireplace that is located off the Formal Entryway inside the front door & across from the Kitchen. A significant amount of modernization has been performed by the present owner. The Kitchen and all 3 Bathrooms were completely remodeled recently with quality finishes throughout. The Kitchen was finished with Thermador Appliances and includes 2 Dishwashers. A wonderful, sunny Island and Dining area is located at the end of the Kitchen, near a Dutch door that leads to the rear yard. Major system upgrades include Copper Plumbing, Heating & Central A/C, Windows, Roof, Electrical Panels (one 200amp panel & a 50amp sub-panel in the garage), & all cast iron Drain Lines replaced with ABS. A complete Security System is in place for piece of mind as well. On the rear of the large, 7750 sqft lot, the original Garage was finished with drywall, then an approx. 25' x 25' new 2 Car Garage with an elevated roof line was added and attached. The new Garage features a stairway (NOT a pull-down) to access the Attic storage area above it. NOTE: All services are in close proximity to the finished original Garage for easy future conversion into a Gym/Bonus Room, Guest Quarters, or an ADU. An open 15' X 37' concrete pad with gated Alley access completes the rear garage improvements and includes water & electrical connections as well as an RV dump. This is also a great space for toys, boats, & extra cars too. We love this combination of features, upgrades, and location ... you will too!
