Eastbury Manor House is an example of an Elizabethan building situated in the London Borough of Barking and Dagenham in Greater London, England. The house is in the ownership of the National Trust.
The land on which Eastbury House now stands was once part of the demesne of Barking Abbey. It was built in the 1570s by a wealthy merchant Clement Sisley, who purchased the land after the dissolution of Barking Abbey. It was probably the first brick built building in the area at that time; it had glass windows and very high chimneys, indicating the wealth of the owner. Glass was probably imported from Italy as at that time English glass was relatively poor in quality.
