Outdoor living: grassy lawns lead to a rose garden and plenty of patio space.

The estate home at 110 15th Street in Del Mar is described as a “one-of-a-kind compound,” its one-third acre lot nestled into a hillside just across the street from the waterfront Seagrove Park.

Compound or modern masterpiece? Why not both?

A “modern masterpiece” that was “built within a Del Mar historical building,” the home features four bedrooms, five baths, and just over 5200 square feet of living space under roof. While little detail is available on the historical claim, county records indicate an effective construction date of 2004 for the Tudor-style estate, indicating that significant remodeling was undertaken around that date.

In addition to the requisite chef’s kitchen, the home features a media room, study, and large attic with “great viewing windows.” The entire house and grounds are touted as offering “unobstructed ocean views up and down the coastline,” with “whitewater and beach views from every room and deck.” The residence’s “unparalleled architecture, design, and craftsmanship” include touches such as a vaulted ceiling, with glass half-walls exposing portions of the upper level, multiple fireplaces, and a master bath with vessel sinks and oversized, ocean-view soaking tub. If there’s not enough space, the listing notes that plenty of room exists for future expansions.

If you can't see the ocean from your tub, why even take a bath?

As befits a coastal estate, outdoor living is a focus. Prospective owners might “entertain on the enormous ocean-facing terrace” with its custom barbecue and vanishing-edge pool and spa. Elsewhere, “grassy lawns lead to a rose garden and plenty of patio space.”

Entertain in the spa!

In addition to the two-car garage, there’s gated off-street parking for another seven vehicles, billed as “a rare find at the beach!”

Patio living at its finest.

The home is billed as being “within walking distance to Del Mar’s finest restaurants, shops & attractions — including the luxurious L’Auberge Hotel & Spa & the world-famous Del Mar Racetrack,” which is just over a mile away.

“Live the California dream & watch the sunset & surfers in total privacy!”

Public records indicate the home was last sold in 1996, to the Harvard-educated husband-and-wife architectural team of Michael Batter and Janice Kay. The pair’s firm, Batter Kay Associates, has designed a host of projects ranging from residential to commercial, most in the North County region.

The home’s assessed value in 2017 was just over $2.5 million, carrying with it an annual property tax bill of $26,200. The sellers believe it may be worth a few dollars more today.

Previous listing attempts have listed the property as high as $24,995,000 in recent years, but none have apparently attracted a buyer. More recently, the 15th Street estate hit the market again in early May, this time carrying a reduced asking price of $19,900,000 that remains unchanged to date. ■
