In 1804, Francis Justice, who was in possession of the estate at the time, was allotted over two acres on the green north of the house.
As a result of this enlargement of the curtilage, The Abbey now stands in the midst of extensive grounds and is approached by a lime tree avenue across the enclosure allotment, leading near to the east of the house.
Although the avenue across the grounds appears to have existed before the enclosure (some trees are older than 1804) the house stood on the eastern edge of its curtilage until 1798.
The old boundary wall survives, only circa two meters beyond the east wall of the house.
The perimeter is indicated by old stone walls, wooden fencing and dead hedging.

Some four and a half acres of the land are used as gardens.
On the north lawn, there is a plane tree surrounded by daffodils.
Here grow ash, beech, bramble, various conifers, field maple, ivy, oak, rhododendrons and sycamore trees.
There are also laurels, winter-flowering Viburnum, snowberry, a young Japanese cherry and maple.
A trunk and several branches from an old copper beech serve as a place for fungi and lichens to grow on.
Under the trees, there is a purpose built wood store.
On the west lawn, there is a London planetree.
The south lawn has a labyrinth in it, where the maypole is erected.
This lawn as young redwood and several varieties of apple and plum trees.
Furthermore, The Abbey has mature live oak, yew, wild cherry, bird cherry, mulberry and a cedar of Lebanon.
In 1991, a project was completed which took care of the trees and transplanted various species around the grounds.
Adjacent to the grounds, there is a small secluded orchard where honey is produced from The Abbey's own mason and honey bees.
The guest house area contains apple, elder, ivy, spindle, wayfarer and yew alongside plants like  climbing roses, ferns and sage.

The courtyard garden has a fig tree, Magnolia, roses and a medieval style flower bed surrounded by a mature Buxus hedging.
This garden was restored during the 1990s with gravelled paths and redesigned by B. Vellacot, a local volunteer.
Around the main building there are flower beds with plants such as catnip, curry plants, Fuchsia, lavender, periwinkle, rosemary, sage, Siberian bugloss, spirea and winter jasmine.
Near the kitchen, there is a herb bed underneath a silver birch.
The walled kitchen garden has a wildflower meadow, a cut flower bed, a bed with strawberries and trees including damson, fig, greengage, morello cherry, olive, pear, plum and quince.
Vegetables grown in the kitchen garden are artichoke, carrot, chard, courgette, kale, leek, maize, marrow, potato and pumpkin, which are used for consumption.
There is also a greenhouse where The Abbey grows winter rocket, parsley and coriander among others.
The walls are flanked by shrubs including Buddleja, dogwoods, musk mallows, elder and mock-orange.

The grounds have resident muntjacs and common wild animals include hedgehogs, grey squirrels, foxes, shrews, voles and woodmice, besides many insect and bird species.
The Abbey has also had sighting of the common pipistrelle, the serotine bat and the rugged oil beetle (a rare Meloe species).
