A Moment in London’s History – The “first PM” moves into 10 Downing Street… July 18, 2016

With the recent change at 10 Downing Street – David Cameron out/Theresa May in – we thought it a good time to look back at when the man considered Britain’s first PM moved in.

Sir Robert Walpole, commonly considered Britain’s first Prime Minister although he was never formally known by that title, was actually First Lord of the Treasury when in early 1730s King George II presented him with the terrace house at 10 Downing Street, off Whitehall, and the large mansion behind it (in fact the title of ‘First Lord of the Treasury’ can still be seen inscribed on the brass letter-box on the property’s front door).

Sir Robert accepted the king’s gift, but only on condition that it be made available to all future First Lords of the Treasury And he didn’t move in until 22nd September, 1735, having had architect William Kent join the terrace house with the mansion behind it before doing so.

Kent had joined the houses on two levels with the main entrance facing onto Downing Street instead of Horse Guards. The Walpoles would live at the back of the new house where Kent had created a series of grand rooms – suitable for receiving honoured guests – and had built an unusual three sided staircase which remains a star sight of the building today.

Walpole used the ground floor of the new property for business and set-up his study in what is now the Cabinet Room. Lady Walpole used the upstairs room now known as the White Drawing Room as her sitting room and what is now called the Terracotta Room (although the name of this room changes with the colour scheme) as the dining room.

Among those who attended 10 Downing Street during the Walpole’s residency were luminaries such as Queen Caroline (wife of King George II) as well as prominent politicians, writers and military figures.

The Walpoles left in 1742 and it was more than 20 years later before another First Lord of the Treasury moved in.
