Completed over a five-year construction period from the ground up, Cowell was involved in every aspect of the design of his LA home, “right down to the doorknobs.” Considering Cowell’s renowned affinity for a lavish lifestyle, you would expect his Beverly Hills home to include the best of personal luxuries, and it does. The 6-bedroom 6-bathroom mansion, which is just off Sunset Boulevard, features a high-tech media theatre, professional tanning salon, state-of-the-art gym, luxury spa complete with wet steam room and professional side-by-side massage tables, a solarium, lap pool and an exterior pool cabana with a large remotely activated retractable roof. Other decidedly extravagant personal luxuries include a separate live-in Butler’s and Maid’s quarters and a 24hr Servants kitchen as well as a $1.0 million security system that reportedly includes retina/fingerprint scan authorization.
