Architectural trophies are found far and wide throughout Greater L.A., but few have an “X Factor” like L.A. Reid’s new home. The music executive, producer and television competition judge recently paid $17.99 million for a modern mansion on the Westside, and it’s quite a sight to see.

Completed in 2015, the modern tour de force boasts a voluminous floor plan set off by black granite walls, brilliant chrome accents and white oak floors. Pocketing walls of glass blur the lines between indoor-outdoor space while taking in city and ocean views.

More than 11,200 square feet of polished space includes a massive living room divided by a two-sided fireplace, a gym, an office, a 300- bottle wine cellar and a home theater with a wet bar. A modern chandelier tops a formal dining area, and a chef’s kitchen has light wood cabinets, two islands and a bar.

The light woodwork continues in the master suite, which has another fireplace and a view of the grounds. There are seven bedrooms, seven bathrooms, three powder rooms and four fireplaces in all.

Two floating glass staircases and an elevator service each of the home’s three floors.

An infinity-edge swimming pool with a baja deck straddles the edge of the grounds, with the property tapering off down the hillside below. Adjacent to the pool is an outdoor kitchen/bar and a spa. A large terrace-balcony extends off the second level.

Although the area containing the 1-acre estate is generally accepted as Bel-Air, the L.A. Times Mapping Database considers it part of Beverly Crest.

The house came to market last summer for $27.5 million and was more recently listed for about $20 million, records show.

Aaron Kirman of John Aaroe Group and Drew Fenton of Hilton &Hyland, an affiliate of Christie’s International Real Estate, were the listing agents, according to the Multiple Listing Service. Jesse Lally, also of Hilton & Hyland, represented the buyer.

Reid, 60, has worked with such top-tier talents as Usher, Outkast and Sean “Puffy” Combs. He cofounded LaFace Records in the late 1980s and later headed up Def Jam Music Group for more than a decade before becoming the chairman of Epic Records, a division of Sony Records.

He served as a judge on the television music competition show “The X Factor” in 2011-12.

Catwalking out of the Westside

Tyra Banks has officially put the sale of her Beverly Hills home to bed. The 1920s Spanish Colonial mansion once owned by actress Marion Davies recently changed hands for $6.33 million, or about $170,000 shy of Banks’ most recent asking price.

That’s a nice return on investment for the model and television personality, even with the estimated $2 million she put into renovating and restoring the home. Records show Banks bought the property more than a decade ago for $3.085 million.

Sitting on a quarter-acre of grounds, the estate is entered through a gated courtyard with a fountain decorated in handcrafted tiles. A rustic clay-tile roof and pronounced rotunda entry lend a distinctive look to the exterior.

The 5,740 square feet of living space is dotted with preserved and architectural elements. Vintage French doors and hardware, clerestory windows and colorful tile risers are among the interior touches. Travertine stone and maple-wood planks line the floors.

Aremodeled kitchen, library, gym, sunroom and formal dining room are among the common areas. A great room topped with rustic beams takes in a view of the grounds. The master suite, one of four bedrooms and six bathrooms, boasts a model-worthy walk-in closet and a safe room.

Outdoors, the fenced and hedged setting includes a swimming pool and a pavilion with a fire pit. An alfresco kitchen/dining area, one of Banks’ additions to the home, has seating for 12.

There’s also a three-car garage. Banks, 42, is a former Sports Illustrated swimsuit issue cover girl and Victoria’s Secret model. She hosted “The Tyra Banks Show” from 2008 to 2010 and has been an executive producer and judge on the reality series “America’s Next Top Model” since 2003.

She owns other real estate in New York and Los Angeles County.

Heidi Lake of Sotheby’s Inter national Realty was the listing agent. Richard Maslan of Hilton & Hyland, an affiliate of Christie’s International Real Estate, repped the buyer.

Singer pushes a high note in Malibu

French singer and composer Sebastien Izambard of the popopera quartet Il Divo has a home in Malibu on the market for $15.9 million.

Sitting on 4-plus acres above Zuma Beach, the estate centers on afive-bedroom main house that offers a contemporary play on the farmhouse style. The whitewashed home, built in 1979 and restored during Izambard’s ownership, features dramatic cathedral ceilings, light French oak floors and meticulously placed skylights for a light and airy feel.

The centerpiece living room has elegant gothic-style windows that take in garden and ocean views. An open-plan chef’s kitchen and dining room area have bifolding doors that open to the grounds. There’s also a screening room.

Including a one-bedroom guesthouse and a two-bedroom barn, there are eight bedrooms and 4.5 bathrooms in 6,000 square feet of space. The barn, in particular, has a vintage vibe with surfboard accent pieces, sets of bunk beds and a bathroom with shower lined on corrugated metal.

Various patios, outdoor eating areas, vegetable gardens and playgrounds fill the scenic grounds. There’s also a northsouth tennis court and a horse corral.

DeeDee Cortese of Coldwell Banker Residential Brokerage holds the listing.

Izambard stands to make a tidy profit on the property. Records show he bought the house in 2011 for $4 million — about a quarter of his current asking price.

The 43-year-old musician has released nine albums with Il Divo, the classical crossover group created and promoted by Simon Cowell, plus a number of collaborative records. The group will begin its U.S. leg of its Amor & Pason tour later this year.
