Belgravia

Belgravia is a district in West London inside the Royal Borough of Kensington and Chelsea. It includes very pricey residential properties and is considered to be among the wealthiest districts in the world. It lies south west of Buckingham Palace. The area gets its name from one of the Duke of Westminster’s subsidiary titles, Viscount Belgrave.

Belgravia’s Grosvenor Estate is still owned by a family property firm, namely the Duke of Westminster’s Grosvenor Group. However, the estate has been required to sell a lot of its freeholds to its tenants, as a consequence of the Leasehold Reform Act 1967.

The majority of Belgravia was previously owned by Richard Grosvenor, 2nd Marquess of Westminster, who created it in the course of the 1820s and onwards. Thomas Cubitt mostly worked on the project. You'll discover lots of grand terraces at white stucco homes focused around Belgrave Square and Eaton Square. A lot of embassies are situated within this area, particularly in Belgrave Square.

Pimlico Road, on the southern side of Belgravia, is well known for its antique shops and high-end furniture showrooms. 1 established brand along the road is Arthur Brett. Despite these shops, it’s a quiet district of London and neighbouring districts are a lot busier with a lot more shops, offices and hotels.
