13523 Hartland St Distinctive mid-century architecture, exceptional custom craftsmanship, and an extensive list of thoughtful upgrades come together in this one-of-a-kind Southern California split-level home. The unique floor plan is an important part of the home's design: the primary bedroom is located on the main level, while the two secondary bedrooms are positioned on the opposite side of the home on separate levels. One secondary bedroom is a loft-style space reached by a short set of stairs, while the third bedroom is located on the lower split level. Buyers should note that the home's multi-level layout includes several sets of interior stairs connecting these spaces.Natural light pours in through clerestory windows, skylights, glass-block walls, and expansive glass, creating bright, open living spaces while maintaining a remarkable sense of privacy.At the heart of the home is a true cook's kitchen built with an extraordinary level of precision. Custom Europly 13-core maple cabinetry was fitted to approximately 1/16-inch tolerances and finished with hand-selected, quarter-sawn figured teak, book matched for continuous grain across the cabinetry. Dovetail drawers, soft-close hardware, heavy-duty slides, custom storage solutions, an appliance garage, and a New York-style wall pantry reflect the same attention to detail.The kitchen is finished with 2-1/4-inch Caesarstone quartz, a 10-foot cast-glass feature, a 36-inch Kohler stainless sink, Grohe fixtures, InstaHot, and a five-stage reverse-osmosis system with UV filtration. Premium appliances include Thermador double ovens, warming drawer, cooktop and glass vent hood, plus a Miele built-in whole-bean coffee system and Miele steam oven. Two 4' x 4' skylights and layered Lutron scene-controlled lighting complete the space.The adjoining great room features warm wood flooring, soaring ceiling lines, architectural glass block, a dramatic fireplace, and generous areas for living and dining. The split-level configuration creates distinct zones throughout the home, with the primary suite on the main floor and the secondary bedrooms separated across the upper and lower levels.The upgrades continue throughout the property. The garage is equipped with two EV charging hookups, the roof is approximately six years old, and the fully paid-off, operational solar system allows the next owner to benefit from existing solar without an outstanding solar lease or payment.The outdoor systems have also been thoughtfully upgraded. The yard is set up with drip irrigation and a weather-responsive irrigation system that measures rainfall and automatically adjusts watering based on the amount of rain received. The backyard is also prepared for a future outdoor kitchen, with gas lines and supporting infrastructure already in place for installation.Mature palms and established landscaping surround the swimming pool, creating a private setting for true Southern California indoor-outdoor living.This is a home where the upgrades are as significant as the architecture itself, with substantial improvements in energy efficiency, water management, electrical capacity, kitchen functionality, outdoor infrastructure, and overall livability already completed for the next owner.
