Go inside this £22.5 million house in one of London's most expensive neighbourhoods

St. John's Wood, an area in northwest London, is one of the most exclusive and expensive places to live in the city. According to a 2014 study, residents here pay the highest average weekly rent in London. In 2015, the average house price in the area is just north of £21 million ($32 million).

One of the most recent houses to sell in the area is 42 Avenue Road, a mansion with six bedrooms, three bathrooms, and two reception rooms as well as a whole spa, including swimming pool and steam room. The house also includes a separate living area for staff.

Redesigned by Celia Sawyer, a businesswoman who remodels high-value homes, the property features lavish trimmings that signify its status as one of the most expensive homes in London. Sawyer described the house as "a residence of distinction not to be missed" in press materials.
