The houses in Eaton Square are large, predominantly three-bay-wide buildings, joined in regular terraces in a classical style, with four or five main storeys, plus attic and basement and a
mews house behind. Most of the houses are faced with white
stucco, but some are faced with underlying high-quality brickwork. Sides are set apart apart. As to roads: the whole rectangle is divided into six compartments or zones as it is bisected lengthways by the Victoria or
Buckingham Palace approach way to the
King's Road which is very diversely and briefly successively named northeast of
Sloane Square). Crossways, it is spanned by four less important roads, all of which change name before, during, and after their transit across the square. All of the roads while in transit across the square assume the name
Eaton Square and most of them are one-way, with no full outer circuit in any one direction permitted or possible. In 1900, the Welsh Industrial Association held an exhibition at 83 Eaton Square, rented by the
Winifred, Countess of Dundonald, the event was visited by
Alexandra, Princess of Wales. The person presiding over the refreshment room exhibition was Kathleen, Duchess of Wellington, assisted by Mrs A. J. Warden, with a party of attractive ladies wearing the national costume of Wales accompanied by
Ivor and Albertina Herbert of Llanover's Harpist playing for the occasion. Between 1916 and 1917, building 87 briefly became the "Countess of Dundonald Hospital", treating many of the wounded in the Great War,
George V and Queen Consort
Mary of Teck visited the patients at the hospital, they were greeted by the Staff and Countess of Dundonald herself. Before World War II, homes on the street ranked as those of the
upper class but was outranked by comparators in
Belgrave Square,
Grosvenor Square,
St James's Square or
Park Lane. The aftermath of that war saw most of those converted to commercial and institutional uses, leaving the square almost wholly residential, raising its prominence. Some of the houses remain undivided but many have been internally converted into flats or multi-storey instances (
maisonettes) by permission or instruction of the
Grosvenor Estate. These are often lateral conversions – that is, they cut across more than one of the original houses – let under typical
long leases across the uppermost price bracket, their exact price depending on size, lease duration and amenity. The façades of the square remain as imagined and built. Most but not all of the freeholds still belong to the Grosvenor Group.
Hugh Grosvenor, 7th Duke of Westminster, who inherited the
Duke of Westminster title from his father
Gerald Grosvenor in 2016, uses one as his London home. Until the 1920s, his predecessors lived in
Grosvenor House the mansion forerunner to the
Grosvenor House Hotel on Park Lane facing
Hyde Park. Co-fronting the north-east end is
St Peter's, a 200-feet-long, tree-lined
Church of England church, in a classical style, fronted by a six-columned
Ionic portico behind which is a slender clock tower. It was designed by
Henry Hakewill and built between 1824 and 1827 (during the square's building). Between 1940 and 1944 the
Belgian government in exile occupied its three numbers which have been long used as that country's embassy in Britain and further premises in central London as their lesser homes and offices. ==Fictional references==
