We love a good penthouse apartment and Heron International has launched two that we can't stop staring at. Found in London's 36-story Heron, which is the first major residential development in the city in the past 30 years, the penthouses are spread out across the 35th and 36th floors and are offered for £12 and £18 million (around $20 and $30 million).
One luxury penthouse offers 6,000 square feet of living space with four bedrooms and four baths, while the other penthouse is 4,000 square feet with three bedrooms and baths. Both give amazing "triple-aspect views" of London thanks to double-height spaces with floor-to-ceiling windows.
