When Nikolai Haas discovered his Los Angeles abode it had a dated 1985 structure, so the designer along with his wife, fashion stylist Djuna Bel, took matters into their own hands by creating a magical mash-up of hippie hut and high collectable design.

The transformation of the residence—accomplished largely by Haas and his friends, carpenter Lauren Mollica and furniture designer John Pope—involved removing unnecessary walls, adding decks and gardens, and redoing the floors and fixtures, all in the service of making it more amenable to socializing and enjoying the great outdoors. But obviously, the focal point of the home has to be the designer’s collectable design collection, as well as his own creations.

All the stonework in the kitchen, bathrooms, and decks was made with the same pele de tigre marble that Haas and his twin brother, Simon, used to fabricate the sprightly furniture, fixtures, and sculptures that, at least in part, have elevated the duo to superstar status in the contemporary design world.

There are signature Haas Brothers designs throughout, including the hand-carved walnut furniture in the kitchen, ceramic accretion vases with porcelain slip, and bronze sculptures that look strangely similar to the Road Runner’s feet. Haas himself handcrafted the voluptuous walnut column on the upper stair landing and the footed bed in the master suite, the concrete pizza oven in the outdoor kitchen, and the whimsical frog-faced toilet seat in the pink powder room.
