If you've been searching for a main-floor primary suite, a flat half-acre lot, and Kirkwood School District — all under $600,000 in Des Peres — this is the one you've been waiting for. Set on nearly half an acre of beautifully flat, usable ground in one of Des Peres' most established neighborhoods, this 1.5-story home offers 2,724 square feet of total living space across three levels — including a fully finished walk-out lower level that most buyers don't expect and can't stop talking about after the showing. The main floor is designed for real life. A stunning stone fireplace anchors the living room, and a wood-paneled den with its own brick fireplace gives you a second gathering space — or the home office you've been looking for. Two fireplaces. Genuine warmth. The kitchen features a center island, generous pantry, and a sunny breakfast room overlooking the backyard. The adjacent family room opens directly onto the back deck, creating a seamless flow for indoor-outdoor living from the moment spring arrives. The main-floor primary suite is a standout. What was once two separate bedrooms was thoughtfully reimagined into one spacious retreat — complete with a dressing area and multiple closets. A second bedroom on the main floor keeps guests or family close. Upstairs, the oversized third bedroom tucks into the upper level with a private, hideaway feel — ideal for birds that return to the nest, a studio, or a flex space. The walk-out lower level expands this home well beyond what the above-grade square footage suggests. A full second family room, an oversized sleeping room that functions as a fourth bedroom, and a third full bath make this level as livable as the main floor — perfect for multi-generational living, long-term guests, or a dedicated recreation space. Then there's the backyard. Nearly half an acre of flat, open, fenced ground in Des Peres is genuinely rare at this price point. Pool-ready. Play-ready. Whatever your vision for outdoor living, this yard can hold it. Kirkwood School District. Property taxes of just $4,773 per year — under $400 a month. Two-car attached garage. Public water and sewer. Natural gas heat and central air. These aren't small details — they're the kind of numbers that make a real difference in your monthly cost of ownership. Des Peres, MO 63131.
