Once you've navigated your custom-designed garage, you pass through an airlocked decontamination zone set between two blast doors, the first of which is controlled by a multi-biometric reader, which uses not only facial scanning but also iris- and palm-recognition technology.
Inside the sanctuary, you're greeted by an impressive entrance hall, which leads to a luxurious lounge, as well as a fully secured space for confidential discussions so that business can continue no matter the circumstances above ground.
A discreetly concealed button turns opaque walls transparent, revealing an underground garden and the adjoining art gallery (pictured). Constructed to the same anti-intrusion standards as commercial bank vaults, the gallery boasts top-of-the-line fire protection, ventilation, temperature and humidity control systems to keep everything in perfect condition.
