The structure of Suffolk barns varies considerably. There is little good building stone in the county so there are many timber-framed barns such as those at The Museum of East Anglian Life, Snape, Alpheton Hall Wyken Vineyard and Wingfield Barns. Later timber- framed barns tended to be unaisled with curved knee braces.
There are also some fine early brick barns. The local builders were also experts in the use of flint with brick. One of the finest examples of the latter is the Great Barn at Manor Farm in Somerleyton in the north of the county.
