Chapel Street, Belgravia, London, SW1X

An unmodernised family house with local authority planning consent to create a residence of 3595 sqft with the benefit of a lift and a newly designed basement leisure suite.



Description

This is an exciting opportunity to extend and modernise this historic house subject to obtaining the necessary consents.
This enchanting unlisted family house, dating from the early 19th century, exudes timeless charm with its traditional brick construction and classic slate-tiled pitched roof. Spread across a basement, ground floor, and four upper levels, the home also benefits from a bright southeast-facing patio garden at the rear.
The current layout follows a traditional configuration, with the dining room and kitchen located in the basement and a beautifully appointed drawing room on the first floor. Five spacious bedrooms provide generous accommodation, offering plenty of room for family living or entertaining guests.
Planning consent has been granted by the City of Westminster (dated 25th July 2025, ref 25/01535 and runs for three years from this date) for a thoughtfully designed basement extension, including the replacement of the existing conservatory with a stylish single-storey lower ground floor extension. The plans also include new windows to the rear elevation and the addition of skylights to the main roof, flooding the home with natural light.
A key feature of the proposed renovation is the installation of a lift servicing all floors from the new basement to the fourth floor. Once complete, the house will extend to approximately 3,595 square feet, offering spacious, elegant living in one of London’s most desirable locations.

Next to the prestigious Belgrave Square, the house enjoys an enviable location in one of London’s most celebrated neighbourhoods.
Belgrave Square itself is regarded as one of the grandest and most imposing garden squares in London.

As a privileged resident on the Grosvenor Estate, exclusive access is granted to the immaculate Belgrave Square gardens and tennis courts, offering a serene and secure sanctuary in the heart of the city.

Access and use of Belgrave Square gardens is at the discretion of Grosvenor Estate and there is an annual charge of £650 for two fobs plus a £100 joining fee for the current year.
The world-class shopping destinations of Knightsbridge, Sloane Street, and Kings Road are all within easy reach, while the vibrant café culture of nearby Motcomb Street and Elizabeth Street provides an inviting social scene. Situated on the eastern edge of Belgravia, the home is only 0.3 miles from Hyde Park with the sophistication of Mayfair, and the bustling excitement of the West End just beyond. Convenient transport links include Hyde Park Corner Underground station (Piccadilly line), just 0.3 miles away, and Victoria station (Victoria, Circle, and District lines, plus national rail services), a mere 0.5 miles from your doorstep.
Belgravia’s distinguished heritage dates back to the early 19th century, when it was masterfully developed by Thomas Cubitt following a special Act of Parliament in 1826. Belgrave Square, once part of the rural expanse known as the Five Fields, now stands as a testament to timeless elegance and architectural grandeur. The land was originally part of Ebury Farm, acquired by the Grosvenor family in the 17th century through the historic marriage of Mary Davies to Sir Thomas Grosvenor.
Today, Belgravia epitomizes refined London living. An exclusive enclave renowned for its sophisticated charm, beautiful white stucco terraces, and leafy squares. It is a coveted sanctuary for those seeking both privacy and prestige in the heart of one of the world’s most vibrant capitals.
