One of London's most exclusive residential areas has a mansion on the market. The property is being sold for the first time in its current condition, which was recently created by knocking the inner walls of two adjoining luxury terraces to create one mansion, a process which has already been completed. Buying the house would cost you 25 million dollars, or $31.3 million, for a 150-year lease which started in 2015. People who returned to the city after the Pandemic were looking to move closer to work and have more space at home. The sales of multimillion-pound properties grew in January and February compared to the previous year, according to property data platform, LonRes. The prices are going up because of the growing interest. Take a look at one of the most expensive properties in London. The property is currently on the market and has been stripped down to its bricks. According to the director of Arlington Residential, a luxury real estate agency listing the property, a buyer will have to complete an internal fit out before they can live in the house. The two Grade I listed buildings on Cornwall Terrace were combined to create the shell of the new mansion. The diving wall that separated the two first floor drawing rooms was removed to create a larger room. One large master suite was created on the floor above. The mansion has planning permission, as well as consent from the Crown Estate and listed building consent to be internally refurbished. The images on the property listing are indicative of what the property could look like once completed, but the buyer can go in any direction. Some of the historical elements of the house, such as fireplaces, are protected. One of the UK's most expensive property transactions occured on the street. One Cornwall Terrace, which is located on the same block of town houses, sold for over $100 million in March. Marcus Cooper, a property trader, purchased the mansion which has seven bedrooms and nine bathrooms. The members of the Qatari ruling family bought One Cornwall Terrace, as well as an adjoining property, for 120 million dollars, but it is not clear whether they bought it from Cooper. The family avoided around 20 million pounds in Stamp Duty by using offshore shell companies, according to leaked documents. There is no implication that the ruling family or the property sellers acted illegally. The embassy in London did not respond to the request for comment. Keep reading.
