1931 Hanscom Drive Rare development opportunity in South Pasadena's highly desirable Monterey Hills neighborhood. Save years of planning and municipal review with this entitlement-ready hillside parcel, featuring Planning Commission-approved plans for a modern 2, 394 sq. ft. residence. Designed by Wise Work Studio, a Harvard alumnus-led architectural practice, this exceptional layout reflects brilliant spatial planning. By combining strategically rotated floor plates for panoramic views with secured city exceptions to maximize buildable square footage, the design unlocks significantly more living space and indoor-outdoor living than typical hillside lots allow. The highly versatile floor plan features a 1, 664 sq. ft. 3BR/2BA main residence paired with a 730 sq. ft. 1BR/1BA attached ADU. Use it as one expansive 4BR/3BA custom home or keep the ADU separate as a guest house, multi-generational suite, or high-yield rental. Situated in an award-winning school district with street utilities in place and established homes flanking the lot. Final building permits are anticipated by late 2026. Buyers or developers have the rare option to collaborate directly with the design team during final plan check to customize interior layouts and finishes to their exact lifestyle.
