Chough Residence (Los Angeles, CA)

Overview

At the top of Mulholland Drive, just outside Los Angeles, CA. sit some of the most luxurious and expensive homes in the country. In 1992, the Mulholland Scenic Parkway Ordinance was adopted by the L.A. City Council in response to public concerns that the majestic views were threatened by unrestricted development. The Ordinance seeks to ensure that all residential dwellings are compatible with the Scenic Parkway environment and therefore restricts building height regulations.

The Chough Residence underwent a full renovation and an addition which included new heating & air conditioning. With more than 6000 sq. ft. of floor area and no attic space, the challenge was how to condition the structure and comply with the Scenic Parkway Ordinance.

Strategy

The architect in charge of the project, Andrew Alper with Design Arc, knew the air conditioning issue had to be resolved during the design development phase of the project, so he brought in Joel Cohen of DARCO Heating & A/C. Just coming off a large project involving The Unico System, Joel knew it was the solution they were searching for. Unico’s Design Department performed the load calcs & duct design, and worked closely with Joel on a shop drawing review.

It was decided that three Unico “4860” 5 ton units be installed, and due to the space constraints, the air handlers feature custom ductwork that is rectangular in design and fits inside the framing of the roof. The Unico slotted outlet was chosen by the architect due to the fact that it would blend seamlessly with the contemporary, linear accents that are found in the homes interior. Combined with three York outdoor heat pumps, the Unico System gives the end user an excellent, highly efficient HVAC system, despite significant glazing on every side of the home.

Results

The homeowners now have an incredibly beautiful home. The Unico System provides total comfort and efficiency and the architecturally significant features and style of the home were not compromised. Long live the Mulholland Scenic Parkway!
