Tucked into one of Richardson's most coveted pockets on a rare cul-de-sac in Arapaho Heights- this 1961 beauty has been thoughtfully reimagined into something genuinely one of a kind. Covered porch, original built-ins, warm wood floors, brick fireplace, and a sense of calm that's scarce in the North Dallas suburbs. The kitchen flows the way life does: KitchenAid 5-burner gas range, honed stone countertops, peninsula with counter seating- open to the family and game room and connecting to the front living and dining spaces. French doors draw you to the backyard, and once you're there, it's hard to come back in. The 2020 linear saltwater pool- flanked by patios, lounging spaces, and lushly landscaped gardens beneath a canopy of mature trees - feels more private retreat than suburban backyard. Upstairs, the primary suite offers its own quiet world: spa bath with soaking tub, large shower, double vanity, walk-in closet, and a private balcony overlooking the backyard. A flexible bonus room off the suite offers nursery, studio, or office potential. Downstairs, the original primary suite includes a walk-in shower, dual vanity, seated vanity, and walk-in closet. Two additional bedrooms share a Jack & Jill bath with a dual vanity. Laundry is tucked away, near the back French doors. The detached oversized 2-car garage includes a climate-controlled workspace ideal for a studio or workshop. The converted original garage adds a spacious family and game room to the everyday footprint. Zoned for RISD: Arapaho Classical Magnet Elementary, West Jr. High, and Richardson High. Minutes from UTD, major medical and tech employers, and key commuter routes including 635, Central Expressway, PGBT, and the Dallas North Tollway. Homes like this with genuine character, rare lot, and exceptional location don't come available often in Arapaho Heights. 911 St. Lukes Drive doesn't just look the part- it feels like home from the moment you arrive, and makes you want to stay forever.
