Having most of its own commerce, sport and other amenities, Emmer Green has an arbitrary divide with larger Caversham and a border with Oxfordshire, the county in which both places formerly stood.

Rosehill House, standing in 14 acres of ground, was once part of Caversham Manor, the first building being erected in 1791.

In 1923 it was bought for the Oratory Preparatory School; then from the outbreak of the last war until 1958 it accommodated part of The Salvation Army's headquarters as staff were evacuated from central London.

There is a cycle path to Wallingford and access to Balmore Walk which overlooks Caversham, with views as far as the Madejski Stadium wind turbine.

Altogether the conglomeration forms three wards, i.e. approximately a fifth of the borough of Reading in terms of population however a higher proportion of the land.
