A newly completed three-bedroom duplex penthouse at Six Charles Street in Mayfair is on the market for £10.5 million, offering 2,027 sq.ft. (188 sq.m.) of internal space and a private 246 sq.ft. (23 sq.m.) rooftop garden terrace.
The penthouse occupies the fourth and top fifth floors of a boutique development on the site of the celebrated potter Josiah Wedgwood’s former London showroom and pied-à-terre.
Developed by REDD Real Estate behind a striking Italianate stucco façade, the building has been remodelled to provide a collection of luxury apartments.
Architectural design is by MSMR Architects, with interiors by 1508 London. Residents benefit from a concierge, passenger lift to all floors, and a double-height entrance foyer.
ILLUSTRIOUS HISTORY
The grand building at Six Charles Street has an illustrious history. The original Georgian townhouse was built in 1750 and in 1765 became the Mayfair showroom, warehouse and pied-a-terre of acclaimed English potter Josiah Wedgwood (1730-1795).

Wedgwood had established his famous Wedgwood pottery company in 1759 and in the early 1760s leased a property in Grosvenor Square to act as his London showroom and pied-a-terre/office but quickly outgrew the premises.
In 1765 Wedgwood acquired Six Charles Street with the ground and first floors providing display rooms for his magnificent pottery lines, with the upper floors serving as a warehouse and the top floor (now the site of the new penthouse) occupied by Wedgwood’s Mayfair pied-a-terre/office.
ROYAL PATRONAGE

Queen Charlotte, the wife of King George III, made famous by actress Golda Rosheuvel and the Netflix Bridgerton miniseries, was Wedgwood’s loyal Royal patron.
The Queen frequently ordered Wedgwood pieces from the Six Charles Street showroom and allowed Wedgwood to name a line of pottery she had purchased ‘Queen’s Ware’.
The Queen also authorised Wedgwood to display the Royal Warrant on company stationery and marketing.

Other patrons of Six Charles Street included Georgiana, Duchess of Devonshire, (portrayed in 2008 by Keira Knightley in The Duchess) and so successful was the Royal and aristocratic endorsement of his Mayfair showroom that in 1767 Wedgwood wrote: “The demand for cream and ivory coloured ‘Queen’s Ware’ still increases, it is amazing how rapidly the use of it has spread almost over the whole globe.”
In 1773 Russian Envoy-Ambassador Aleksey Musin-Pushkin visited the Wedgwood showroom on behalf of Empress Catherine the Great (characterised by Helen Mirren in the 2019 Sky-HBO miniseries).

The Empress ordered the Imperial Green Service from Wedgwood consisting of 952 pieces, produced in Wedgwood’s factory-studio in Chelsea, and now displayed in the Hermitage Museum in St Petersberg.
In 1795 Wedgwood died and in the 1849 the building at Six Charles Street was remodelled to keep up with Victorian fashions, with more opulent interiors and the grand Italianate white stucco facade created.
It then served as the Mayfair mansion of art critic John Ruskin where he entertained Thomas Carlyle and Lewis Carroll, before being converted into a collection of grand apartments after World War One.
