Camden is a French-villa estate of roughly 11,900 square feet planned across three levels on a quarter-plus-acre Beverly Hills lot. Above grade, two stories of bookmatched limestone hold the formal rooms, a library, and seven bedrooms; below grade, a full habitable basement becomes a private entertainment and wellness floor.
That lower level is the heart of the house: an acoustically treated theater, a glass wine room, a basement bar, and a sauna and steam suite, with a gym beside the principal suites. Two kitchens, bars on the first and second floors, and an outdoor BBQ kitchen give every kind of entertaining its own room, and the plan opens to a pool and spa on the grounds.
The engineering
The complexity is structural and below grade. HR Development carried the habitable basement and its full waterproofing build-up under a Sika Sarnafil roof, then integrated the estate systems: a sixty-plus-keypad Crestron platform across forty audio zones, a standby generator, a residential elevator, and a concealed vault, holding Italian and custom cabinetry, precast stonework, and ornamental iron to one line across all three levels.
The estate
Programmed across three levels
Camden is planned across three levels. Above grade, two stories of limestone formal rooms, a library, and seven bedrooms; below grade, a habitable basement given over to entertainment and wellness; and outside, a pool, spa, and outdoor kitchen that pull the plan into the landscape. A residential elevator ties the levels together, and the whole estate runs on integrated systems over a fully waterproofed structure.

The build sequence
How it came together
The order the work was solved — from the structure outward to the final finish.
Below-grade waterproofing
A full waterproofing build-up — waterstop at the cold joints, polymer-modified cement, peel-and-stick and bentonite membranes, and drainage board — sealing the subterranean level.
Roof envelope
A Sika Sarnafil roof closed over the structure above.
Amenity infrastructure
The Crestron platform, the standby generator, the elevator, the vault, and the chandelier lift layered in.
Finish, held to one line
Italian and custom cabinetry, precast stonework, and ornamental iron carried across two floors and the level below.
Nº 01Exterior Architecture
The limestone plane
Bookmatched limestone, glass, and landscape resolve into one horizontal line. The street reads as restraint; the precision lives in the joints.
Nº 02Outdoor Living
Grounds and water
Terraces and pool extend the plan outward, and a walkable skylight carries daylight down to the level below.
Nº 03Kitchen
The family & chef's kitchen
A Wolf-equipped chef's kitchen with prep pantry, steam oven, and island beverage center, finished in stone to the datum of the public rooms.
Nº 04Living Spaces
The principal rooms
Above grade the house stays calm and formal, stone and marble held to a single datum across the public rooms.
Nº 05Dining Room
The formal table
A dedicated dining room holds the entertaining program to one room, finished in stone and light like the rest of the public floor.
Nº 06Library
The library
A quiet book-lined room off the principal rooms, detailed to the same limestone datum as the living spaces.
Nº 07Fireplace
Marble hearths
Marble fireplaces anchor the principal rooms, each set as a focal point within the limestone envelope.
Nº 08Wine & Bar
Bars and the wine room
Bars on more than one level and a glass-fronted wine room give every kind of gathering its own room.
Nº 09Staircases
Vertical circulation
A sculptural stair and a residential elevator connect three levels, framed by feature stone.

Marble baths and powder rooms throughout the house, including the primary suite, held to one finish line.

A sauna and steam suite engineered into the lower level as a true wellness floor beside the gym.

The estate, integrated
A Crestron platform of sixty-plus keypads and forty audio zones, a standby generator, and a concealed vault run quietly behind the finish.
Nº 15Construction Progress
Beneath the finish
A full subterranean shell, waterproofed in layers under a Sika Sarnafil roof, is the structure the entire amenity floor depends on.
