Buildwas manor was land previously belonging to the diocese. In the Domesday Book the manor of Buildwas was assessed as one hide and was home to nine households, five of them headed by slaves, four by villeins and one by the reeve. It had a mill and woodland, with 200 pigs. It was then worth 45 shillings, as before the Norman Conquest of England, although the value had slipped a little in the intervening period. The dedication of the abbey was to St Mary and St Chad: the same as Lichfield Cathedral. The foundation charter itself has been lost, but a poor transcription survives among the manuscripts of Roger Dodsworth, now in the Bodleian Library. This was printed by Robert William Eyton, the great Shropshire antiquarian, who considered that the list of witnesses, including parties who were soon afterwards drawn into the civil strife of King Stephen's reign on opposing sides, was designed to suggest an early date for the document – an impression he considered false. The first abbot is named as Ingenulf. The transcript omits details of the bishop's grants to the new abbey. However, these are listed in a confirmation issued by Richard I. Like the transcript, this addresses Roger de Clinton as Bishop of Chester and states that his donation was of Buildwas itself, with its surrounding woodland, assarts and appurtenances; land at Meole, just south of Shrewsbury, with its burgesses and a due (tax) called "greffegh"; churchscot, a due for the support of the clergy, from the hundreds of Condover and Wrockwardine; "et in territorio Licheffelddensi hominem unum nomine Edricum" ("in the territory of Lichfield one man named Edric"). Edric’s rôle is not specified but presumably involved some kind of work on the abbey’s behalf in the diocesan centre.
