Sir Ambrose Phillips purchased the estate following the death of the 3rd and last Beaumont baronet in 1686. Phillips demolished most of the priory church in 1696. On the death of his eventual successor in 1796 the estate passed to his cousin Thomas March, who adopted the surname Phillips in lieu of his patronymic.

In 1833, Charles March Phillips gave the manor of Grace Dieu to his son, Ambrose Lisle March Phillips, following his marriage. Ambrose had converted to Roman Catholicism at an early age, and was an enthusiast for monasticism. His biographer Edmund Sheridan Purcell says his father had been "anxious to see him married and settled lest his religious fervour should induce him to make vows of celibacy, which he often spoke of as the highest life, and follow up by entering the cloister or ranks of the secular clergy" The old priory buildings having fallen into ruins, he set about building a new house to a design in a "Tudor" style by the London architect William Railton. It was built on higher ground, about 300 yards south of the priory ruins. There was a chapel attached, later enlarged by A.W.N. Pugin. In 1842 Phillips built another chapel, to Pugin's designs, about a mile from the house and set up a cross, tall, on a rock he named the Calvary. Between the chapel and the cross was a series of fourteen shrines, each containing a representation of a scene from Christ's passion. At the foot of the rock he built a village school, dedicated to St Aloysius. In around 1846, Pugin also added the mansion's east wing and stable court gateway. Sir Banister Fletcher made alterations in around 1900. The March Phillips family, later March Phillips de Lisle, owned the house until 1933, although their main residence was at the Hall they built at the former Garendon Abbey. Following the death of two of its heads in quick succession, the family needed to tighten its belt and so in 1885 moved out of Garendon and into Grace Dieu Manor. A return to fortune allowed the family to return to Garendon once more in 1907, however. Finally in 1964 Garendon Hall was demolished and the family returned to Grace Dieu for a final time, selling the house within a decade. Grace Dieu Manor then became a Catholic school.. The school was part of the educational trust of the Rosminian order. In 1972 the family moved to Quenby Hall, but following the collapse of the family cheese making business, the family has been forced to offer the Hall for sale.
