Foundation trenches for extension to offices, c.2m deep, cut dark topsoil, presumably a combination of an accumulation of ?topsoil and ?post medieval pits.

Features included a post medieval pit containing C19-C20 material and a small group of unarticulated human bones from one or more disturbed burials.

Medieval boundary ditch investigated during the installation of a water pipeline west of Crabtree Lane.

Excavations on the medieval and post medieval buildings.

Four early Medieval lime pits and a complex of lime kilns (C13-C14).

An archaeological excavation by Colchester Archaeological Trust in 2018 revealed 42 charcoal-rich pits (i.e. pits containing charcoal-rich fills), ranging in date from the Early Iron Age to the post-medieval or modern periods (late 15th to 19th/20th century), as well as a Late Bronze Age/Early Iron Age pit, an Early Iron Age pit, a late medieval pit and a number of undated features. In addition, two medieval or post-medieval ditches were also revealed.

Post medieval brick kiln - Suffolk type.

A small trial-trenched evaluation in 2016 produced small quantities of Roman, medieval and post-medieval finds in the river silts. The report suggests these were probably derived from centuries of dumping rubbish on the river edge. The trench revealed modern soils (L1, 0-1.05m), post-medieval dump (L2, 1.05-1.31m), medieval/post-medieval river silts and gravels (L3-L5, 1.31m-2.24m, starting at 5.45m AOD), and Roman river silts (L6, starting at 2.24m deep, 4.5m AOD).
