Princess Eugenie, who previously lived two miles away at St James Palace with her sister Princess Beatrice, now occupies a three-bedroom residence on the Kensington Palace estate.
After damp was discovered at Ivy Cottage last year, the couple reportedly had to delay their move-in date while repairs were made. However the bride and groom are thought to have made their move in April.
Also in the grounds are newlyweds the Duke and Duchess of Sussex, who have lived in the north-western corner of the west London palace since their marriage in May.
And while the wedding of the Duke and Duchess of Sussex will perhaps prove to be the bigger Windsor event of the year, it is in fact Princess Eugenie and Mr Brooksbank who will enjoy the larger marital home.
The three rooms at Ivy Cottage make it one room larger than the Sussex’s petite two-room Nottingham Cottage home on the other side of their shared courtyard. The Duke and Duchess of Sussex are also rumoured to enjoy two reception rooms, a bathroom, kitchen and a small garden.
Other royals who call Kensington Palace their home are the Duke and Duchess of Kent - who live in Wren Cottage - Prince and Princess Michael of Kent, the Duke and Duchess of Gloucester, and the Cambridges.
Both Ivy Cottage and Nottingham Cottage are dwarfed by the 21-room suite in which the Duke and Duchess of Cambridge live with their three children, which is inside Kensington Palace itself.
All apartments have benefited from a £12 million site-wide refurbishment from 2012 under the management of Historic Royal Palaces.
Royals have been living at Kensington since at least 1689, when William III and Mary II would use the address as their country retreat.
Later, the palace and its buildings would slowly be transformed into a home for younger members of the Royal family and their growing families.
Over the years, Ivy Cottage is believed to have been home to a palace maintenance man, as well as the family of a soldier who had been injured in the first world war.
It is believed that Princess Eugenie and the Duchess of Sussex's shared love of dogs and art has helped the pair bond.
The princess’ life-long enthusiasm for art and her day-job as the associate director of contemporary-art gallery Hauser & Wirth, means that Ivy Cottage is likely to be hanging with many prized art pieces.
When the Duchess of Sussex moved to the UK, she brought her beloved beagle Guy with her. And with Eugenie’s Norfolk Terrier sharing the name Jack with her future husband, their residence has become home to two Jacks in recent months.
When they were younger, Princesses Eugenie and Beatrice lived with their father, Prince Andrew, Duke of York, at Royal Lodge. The 30-room Georgian mansion set, within Windsor Great Park, may seem a world away from the new Ivy cottage address.
The second of Princess Eugenie's two wedding receptions will take place at the Lodge; according to Vanity Fair, her parents are planning to erect a marquee in the grounds for the celebrations to be held in.
