Bloomberg L.P. co-founder Charles Zegar has picked up a nearly historic Colonial Revival style home in Hollywood. The computer scientist and billionaire purchased the home in Sunset Square for a family member, and paid $3.4 million for the property.

The house measures about 3,400 square feet, with five bedrooms and four and one-quarter baths throughout the residence. The kitchen may be the heart of the home; it’s brought off with understated flair with strong commercial design influence, with subway tile, very substantial appliances, and a very contemporary island with breakfast bar and sink. There’s a lot of stainless, but it fits right in, and the nicely contrasted hardwood floors balance out the metallic and the whitewash.

The kitchen, part of an open-concept common area, extends to a glass-flanked dayroom, family room, and living room; the latter is situated for some privacy, and contains a fireplace.

Other modern revisions include lighting and windows, which collectively offer both contemporary and period-cottage appeal.  Bedrooms are toned soothingly, and the master suite features a walk-in closet; the master bath is rendered in muted green, with a set of doors opening onto a balcony.  Bedrooms feature private outdoor sitting areas, and decking on the house is redwood. A small pool is worked into the backyard, beside the two-bay detached garage.

Zegar worked with Michael Bloomberg at Salomon; when Bloomberg left, the story of Bloomberg L.P. began. Zegar’s net worth is estimated at $1.9 billion.
