The exterior of Eastbury Manor House is a superb example of the Elizabethan gentry house. It was constructed using traditional methods.
It has two main storeys, with an attic above, and cellar below. It is built to an H-shaped plan with a brick-walled courtyard to the south.
The English Bond red brickwork is enhanced with 'diaper-work' patterns in grey brick. There is also much use of moulded bricks, notably the pediment of the Transitional-style north entrance porch.
The mullioned and transomed windows were originally finished with plaster, stained to imitate stonework.
