The estate was expanded to include a 16th-century manor house and other buildings. Structures added from the Late Middle Ages to the mid-17th century include a chapel, granary, stables and other buildings. The buildings are all constructed from limestone; which are locally quarried stones that are typically flat and easily stacked for drystone wall purposes.Roman periodIt is known that there was a Roman presence at the site as early as the 5th century AD based upon the archeological finds of carved stones, Roman coins and other discoveries.Many Roman artefacts have been discovered at Calcot, some of which are displayed at the Gloucester City Museum and the Stroud Museum. One of the principal finds is a curved, ornate limestone bas-relief. This stone had originally been embedded in the wall of the tithe barn. This stone is now in the Ashmolean Museum in Oxford.
