The Howick house is a Mesolithic site located in Northumberland, England. It was found when an amateur archaeologist noticed flint tools eroding out of a sandy cliff face near the village of Howick. Investigations found a circle of substantial post holes with charcoal stains in their bases, a number of smaller stake holes, some angled in from outside a hollow, and inside the house a number of shallow hearths filled with charcoal, burnt nutshells and some fragments of bone. Radiocarbon dating of the charred hazelnut shells established that the building was constructed about 7600 BC and occupied for about 100 years, which led to the find being called "Britain's oldest house". This title was disputed in 2010 when the discovery of the even older 'house-structure' at Star Carr in North Yorkshire was announced.
