Tucked inside Heaven Trees on a rare 0.45 acre pond and preserve homesite, 11737 Heather Grove Lane is the kind of Old Florida escape you do not stumble into very often. Mature oaks draped in Spanish moss frame the view, and beyond them the property opens to what feels like your own private sanctuary of water, preserve, and wildlife. Inside, the home is warm, polished, and move-in ready with solid hardwood floors throughout and no carpet. Updated lighting, crown molding, oil rubbed bronze fixtures, and recessed lighting keep the look clean and timeless. You have both a living room and a separate formal dining space, plus a family room with a gas log fireplace for an inviting feel. The kitchen is bright and functional with white cabinetry, Corian countertops, a custom tile backsplash, pantry closet, new Maytag appliances (2026) and a breakfast nook that looks out toward the greenery. But the real magic is outside. The oversized Florida sunroom is made for effortless indoor outdoor living and entertaining, wrapping you in 180 degree views of the pond and preserve. Step out to the paver patio and wood deck, and let the sanctuary do what it does best: slow everything down. The primary suite also enjoys sanctuary views and features an updated zero entry shower, dual sinks, vanity seating area, and dual walk-in closets with an organizer systems. Secondary bedrooms are well sized, and the guest bath includes a tub shower combo with its own vanity seating area. The laundry room has ample storage with built in cabinetry and shelving. Big ticket updates are already handled with a new roof (Dec. 2025) and kitchen appliance (2026), full brick construction creates classic durability, and a long driveway adds extra parking. Heaven Trees is a quiet, established Mandarin neighborhood known for its tree canopy, pride of ownership, and laid back feel, with an active owners association that keeps residents connected.

Mandarin is one of Jacksonville's classic Old Florida pockets near the St Johns River, loved for its natural beauty, local history, and relaxed lifestyle. Zoned for coveted Loretto Elementary, Mandarin Middle, and Mandarin High, all A rated schools. If you have been waiting for a property that feels like a retreat, with a sanctuary view you cannot recreate, this is it.
