5 Northwick Terrace

5 Northwick Terrace is a terraced house in St John's Wood near Maida Vale in London. Shortly after their marriage, around 1918, Agatha Christie and her husband Archie looked around for lodgings in London. Between two options, they chose the one at Northwick Terrace as it was cheaper, with the rent being only two a half guineas a week. They moved in and lived there during the final months of the war.

Christie described their apartment as having a "microscopic kitchenette and a bathroom". They lived there with Archie's former batman, one Bartlett, whom Christie described as "a kind of Jeeves-a perfection" who had once been a valet to dukes. According to Christie, there were many drawbacks to their flat for example the beds felt like they had "large iron lumps". Nonetheless, she enjoyed the company of their landlady, one Mrs Woods.

There are still terrace houses on Northwick Terrace. But the No. 5 today is newly built over the original which was destroyed by bombing during the Second World War. No. 9 and 10 survived and give an idea of what the original No. 5 would have looked like.
