Thanks to XL Services’ close work with the pool company, the proud homeowner of this Hollywood Hills, California home got the pool of his dreams, the one that others said couldn’t be built. XL Services negotiated a first of its kind testing protocol with the City of Los Angeles Department of Building and Safety for the six inch thick glass walls that were a unique installation in the City of Los Angeles. Under careful scrutiny by our principal construction consultant, the tri-level hillside pool successfully passed all required testing.
