It was ever-dogged real estate yenta Yolanda Yakketyyak who let us know that notoriously camera-shy and reluctantly famous Australian pop singer and songwriter Sia — she once posed for the cover of Billboard magazine with a paper bag over her head — and her new husband, documentary filmmaker Erik Anders Lang, splashed out $4.7 million for a magnificent architectural oddity in L.A.’s star-saturated Los Feliz area.

The fearlessly eccentric Mediterranean Revival residence, designed by iconoclast architect AF Leicht and built in the mid-1920s, has five bedrooms and 4.5 bathrooms in about 5,000 square feet of painstakingly restored and sensitively updated interiors, which include fancifully arched ceilings and doorways, colorful stained-glass windows and vintage light fixtures. Roomy formal living and dining rooms — the latter of which steps down to a to-die-for semicircular sunroom with panoramic city views — are joined by a rounded office/library and a comfortably commodious eat-in kitchen with city-view terrace. There’s an additional den and separate game room on the lower level, while the top floor master suite features a private sitting room, separate sleeping chamber, vintage-tiled bathroom with purple tile shower, and a private loggia with unobstructed Downtown view. Terraced gardens laced with tiled paths and curved stairways lead down to a swimming pool that’s set amid private and mature gardens.

The 2015 Grammy performer, whose video for the 2014 single “Chandelier” has been viewed more than 800 million times on You Tube, continues to own a three-bedroom, 1930s bungalow in L.A.’s boho-chic Echo Park ’hood that she picked up in 2012 for nearly $900,000, as well as an idiosyncratic midcentury compound in Palm Springs, originally built as a small apartment complex, which she bought in late 2013 for a tetch less than $1.65 million — and where she and Lang were married last August in a ceremony documented by celebrity photographer Terry Richardson.
