Although no longer a sizeable estate, Felbrigg was at one stage, one of the most important properties in Norfolk, with one of the largest and most productive demesne. The Felbrigg estate covers some 1760 acres of parkland and mixed woodland. The dominant feature is the 520 acre Great Wood which shelters the house.

The estate has particular significance through the connections with Nathaniel Kent and Humphry Repton, both of whom were involved at Felbrigg in the early stages of their careers.

Sheep and cattle graze the parkland that stretches beyond the now solitary village church around which the original Felbrigg village stood.

The Lake, which is invisible from the Hall, was created in the mid-18th century by damming the Scarrow Beck. A pleasant and attractive feature, the Lake has also encouraged bio-diversity.

To the west and north, pasture woodland merges into the Great Wood. Local residents continue to enjoy access to the network of footpaths, many being old rights of way, which run through grassland, woodland pasture and woods. Particular care is taken with veteran trees, and there is a programme for gradual replacement of small 20th century soft wood plantations by hardwoods, notably sweet chestnut, beech and oak, which have long grown here.
