Welcome to SIX SIX ELEVEN CLAYTON, a rare 10-UNIT LUXURY apartment building in the heart of DEMUN — one of the most desirable and enduring neighborhoods in all of St. Louis. Originally built in 1950 and known to generations of locals as the home of the original Katie's Pizza, this 1950 brick landmark was taken down to the studs and rebuilt over a two-year, top-to-bottom restoration. The result is essentially NEW CONSTRUCTION inside a timeless brick shell, with an EFFECTIVE YEAR BUILT OF 2023 per the county assessor.
This is not a cosmetic flip. The building was FULLY SPRINKLERED, FULLY REWIRED, AND FULLY REPLUMBED, with a new roof, new windows, new HVAC, new framing, and new insulation throughout. Concrete floors and demising walls between every unit deliver the quiet, solid feel of brand-new construction — no deferred maintenance and none of the surprises that come with an older building.
Inside, every apartment is finished to a true luxury standard: CUSTOM WHITE SHAKER CABINETRY, QUARTZ COUNTERTOPS, full STAINLESS STEEL APPLIANCE PACKAGES, marble-look porcelain baths, frameless glass showers, and WIDE-PLANK ENGINEERED HARDWOOD floors. Every unit includes an IN-UNIT WASHER AND DRYER, and the common corridors feature herringbone hardwood, raised-panel wainscoting, and Ralph Lauren lighting.
The location is what makes this truly irreplaceable. The property feeds into the top-rated CLAYTON SCHOOL DISTRICT (rated 10/10) — the single most powerful long-term driver of rental demand in the area, and something almost no other building of this size in DeMun can offer. With a WALK SCORE OF 95, residents are minutes from Forest Park, Washington University, BJC HealthCare, and the celebrated DeMun dining scene, in a submarket with a SUSTAINED VACANCY RATE UNDER 3 PERCENT.
For investors, the numbers are just as compelling. The building is 100% LEASED on a clean rent roll, with a diversified base of medical, university, and professional tenants and renewals staggered into 2027 — meaning day-one cash flow with no leasing lift required. The offering also includes 20 PARKING SPACES (15 secured garage plus 5 surface), an extraordinary amenity in DeMun, where on-street parking is the single biggest constraint on rents.
New construction without the new-construction risk, in the best school district in the region, fully leased on day one — opportunities like SIX SIX ELEVEN CLAYTON simply do not come along in DeMun. Proof of funds, bank letter or a snapshot of current portfolio is required to tour as building is fully occupied.
