This is the fourth instalment in an occasional series of posts about Cavendish Square. Outward appearance belies the fact that there is a substantial early Georgian house at 20 Cavendish Square. It is enclosed within a shell of the 1930s that was part of an extensive redevelopment of a larger corner site as premises dedicated to the nursing profession.
The plain brick-fronted three-storey house was built in 1727–9 by George Greaves, a Clerkenwell carpenter. Its first resident was Francis Shepheard, a former MP who had moved from the Whigs to the Harleyite Tories. He was a wine trader and East India merchant in the steps of his father Samuel, who had been Robert Harley’s financier and was Deputy Governor of the South Sea Company from 1713. Francis inherited a fortune when his father died in 1719.
A broad five-bay front permitted a central entrance, but in an almost square plan there is an unusual layout. The house’s finest feature, a painted staircase, among the best of its kind in London, is oddly situated in the south-east corner. The great expense of such decoration may have obliged Shepheard to avoid an open-well entrance-hall form in favour of a dog-leg stair walled off from the entrance hall. This meant orienting the stair to rise from back to front, forcing a landing against the front wall and so causing irregular fenestration. The town-house aesthetic was evidently, and even more than usual, internal. The main staircase walls display two large architectural capricci, attributed by Edward Croft-Murray to John Devoto, the principal scene painter at the Drury Lane Theatre at the time. There are also trophies and grisaille figures of the Arts on the landing and of Music below the southern capriccio, these more in the style of James Thornhill. The ceiling, in contrast, is painted in the manner of William Kent, with gilded hatching and grisaille caryatids supporting a trompe-l’oeil dome.
The next most impressive space in the house, to the north-west on the ground floor, is a fully pilastered room. The quality of this room, and the fact that its Ionic pilasters are sunk at the corners, hint at involvement on the part of James Gibbs, who was stationed just around the corner on Henrietta Street at the time. An imposing marble chimneypiece has a swagged frieze with a Medusa-like mask, plaits tied under her chin, a type widespread in the 1730s. However, flanking eagle-headed terms suggest the fireplace could be datable to the 1750s as double-headed eagles featured in the coat of arms of William Wildman Barrington, 2nd Viscount Barrington. He moved in when he became Secretary at War in 1755. During his tenure the house became known as a place for parties. The Barrington family continued to occupy the house up to 1888.
In 1894 Sir Charles Tennant bought the property as a wedding present for his daughter, Margot, and the Liberal politician Herbert Henry Asquith. The couple lived here with their children and servants before and after Asquith served as Prime Minister from 1908 to 1916. Margot Asquith was a political hostess with a reputation for extravagance. On departing for 10 Downing Street she noted, ‘All the colour, furniture, grates, curtains, and every chair, table, and rug in Cavendish Square I had chosen myself.’ This precedes the disarming admission that ‘It is a constant source of surprise to people of moderate means to observe how little a big fortune contributes to Beauty.’ (The autobiography of Margot Asquith, ii, 1922, pp.103 and 106) After their wartime return, their income much diminished, the Asquiths were obliged to sell in 1920, marketing the property as suitable for ‘a nobleman, embassy or family of distinction’ (Royal College of Nursing Archives, RCN/28/3).
But Annie Pearson, Viscountess Cowdray, bought 20 Cavendish Square to be a clubhouse for nurses. She followed up in 1921–2 by funding rebuilding along Henrietta Street to form a headquarters building for the College of Nursing, established in 1916 in an office on Vere Street as a response to wartime exigencies, to support and advance the nursing profession. This was part of a phased campaign of redevelopment with Sir Edwin Cooper as architect throughout. The first phase included some internal remodelling of the house; Cooper’s neo-Georgian detailing is hard to distinguish from the eighteenth-century work.
The last rebuilding phase in 1932–4 followed the acquisition and demolition of a corner house. Cooper refaced and, through the ingenious introduction of bridging structural steelwork, heightened No. 20, which was used as the Cowdray Club up to 1974. The RCN has since carried out three refurbishments, the most recent of which in 2012–13 saw the opening on Henrietta Street of a public heritage centre with retail and museum elements.
