Although Moyse's Hall has had many different uses over the centuries, and many alterations have been made to the fabric, it remains a rare and important example of Norman domestic architecture. Other surviving urban examples include the Music House in Norwich and the Jew's House and Aaron's House in Lincoln. Almost all the surviving examples date from the second half of the 12th century, as does Moyse's Hall. In many examples, the ground floor was used for storage and business, whilst the first floor formed the living quarters.

Moyse's Hall had two rooms at both ground and first floor level. The main first floor room was the hall, but there was also a second room called the Solar or Chamber which was the private bedchamber of the owner of the house. There is some evidence that there may once have been a third chamber at Moyse's Hall, but if so it has long since been destroyed.

Moyse's Hall is by far the most complete Norman stone house still standing in Bury St Edmunds, but there are other houses with some surviving Norman stonework, usually not visible from the outside. For example, there is Norman work in houses in Guildhall Street, Hatter Street and Whiting Street.
