A San Marino home built from an early 20th century pumphouse that supplied water to Wilson Lake, now Lacy Park, is on the market for $5.288 million.

The walled and gated 4,598-square-foot, contemporary-style house has five bedrooms and five bathrooms. Completed in 1948 and modified numerous times, it sits on a half-acre-plus lot with manicured gardens, several patios and a pool and spa.

Records show the property last traded hands in May 2022 for $4.85 million.

The house, designed by the USC-trained architect Whitney R. Smith for the original owner, builder Phillip Roulac, integrated the original brick utility building. Over the decades, every room has been restored with new doors, hardware, windows and lighting.

Today the open floor plan features a large living room with a fireplace, parquet floors, brick walls, beamed ceilings and skylights. It connects to the dining room, which opens to the kitchen.

A row of French doors open to the grounds.

Elsewhere, the house features a library and a light-filled studio with custom built-ins and a fireplace.

Darrell Done of Coldwell Banker Realty holds the listing.

The brick utility building, constructed in 1934, belonged to the city of Alhambra’s water department.

This was before the establishment of the Metropolitan Water District, the Building Biographer Tim Gregory writes.

Gregory notes that water has naturally flowed through the canyon since as early as the 1700s. In the 1800s, the water powered El Molino Viejo, which served as a grist mill for Mission San Gabriel and the surrounding area.The pumphouse was one of four lots intended to capture and process that water.
