Set along one of Lemon Heights' most beautiful estate streets, directly across from Bent Tree Park and just moments from Peters Canyon and the Mountain To Sea trail, this impressive 5,072-square-foot single-level estate offers sweeping mountain views, generous living spaces, and a flexible floor plan with four ensuite bedrooms and 4.5 bathrooms in the main house. Main house is 3988 sq ft. with 722 sq ft guest house & 360 sq ft bonus room. A freshly painted exterior, wood floors, fresh interior paint, soaring ceilings, and expansive windows give the home a bright, updated feel. The dramatic great room features floor-to-ceiling windows, a cathedral ceiling, fireplace, and wet bar, while the adjoining formal dining room creates an inviting setting for holidays, dinner parties, and special gatherings. Nearby, the media room or den with double pocket doors offers a comfortable space for movie nights, reading, or working from home. French doors from both the great room and primary suite open to expansive decking overlooking a grassy lawn and private yard framed by mountain views, creating a beautiful setting for alfresco dining, entertaining, play, or quiet relaxation. The oversized eat-in chef's kitchen offers abundant cabinetry and counter space, a generous center island, walk-in pantry, and large breakfast nook with plenty of room for casual meals and everyday conversation. Privately situated, the primary suite feels like a true retreat with its own fireplace, high ceilings, beautiful views, a large walk-in closet, direct outdoor access, and a spacious spa-like bathroom. Three additional bedrooms each feature an en suite bathroom, while a powder room adds convenience for guests. The separate 722-square-foot guest house with its own entrance is an exceptional bonus, featuring a newly remodeled full kitchen, comfortable living area, private bedroom, bathroom, and patio-ideal for extended family, visiting guests, potential rental income, or a private work-from-home space. A 360-square-foot finished bonus room with access to the RV garage offers even more flexibility as an art studio, playroom, workshop, or gym. Rarely does a property offer this much space, versatility, and natural beauty in such a desirable Lemon Heights setting. Whether entertaining on the deck, enjoying the changing mountain views, or spending a quiet day at home, this special estate offers an elevated yet easy lifestyle within the boundaries of highly regarded Tustin schools.
