It is on the Buckinghamshire bank, just upstream of Hollyhock Island.

It is privately owned, and has a 5 bedroom 5000 sq ft house - which was marketed for sale at £3m in August 2025 along with Hollyhock Island.<ref>{{Cite web |last=Ryder |first=Liam |date=2025-08-18 |title=Private island hideaway used as royal getaway paradise up for sale |url=https://www.mirror.co.uk/news/uk-news/beautiful-private-island-hideaway-used-35739399 |access-date=2025-08-18 |website=Daily Mirror |language=en}}</ref> On the next door, smaller island of Hollyhock was once a house known as "The Nest", which was used as a hideaway by the future Edward VIII and Wallis Simpson during the 1930s.<ref>Paul Goldsack for English Heritage ''River Thames:In the footsteps of the Famous'' Bradt 2003</ref>

The island regularly floods, and the house built has been designed with a ground floor of void spaces designed to allow the flow of water if and when the island floods. When marketed for sale, it was shared that any future owner might wish to transform the existing house or demolish and re-build a flood-resilient or eco-amphibious house.<ref>{{Cite web |title=Holm Island & Hollyhock Island - Kai Carter Estates |url=https://www.kaicarterestates.com/properties/holm-island/ |access-date=2025-08-18 |language=en-GB}}</ref>
