Overview and Historical Maps

The area that comprises the Oakmount Triangle conservation area formed a small part of the estate of South Stoneham, first defined in an undated 11th century charter, and then defined in more detail in a charter of 1045. By 1127, part of this area had been granted by Henry I to the Augustinian canons and their community at St Denys, and the demesne was further increased by later grants, notably by Stephen (1137). Following the dissolution of St Denys’ Priory in 1536, the main part of the estate was acquired by Francis Dautrey and acquired the name of the Manor of Portswood.

The manor then passed through a succession of owners and was gradually broken up. The Highfield House Estate was one of the fragments.

We are very happy to receive any comments, further information or corrections. We are currently trying to locate maps from the later part of 1910 which show plans or actual new buildings, as well as a 1940 map and some early aerial photographs.

  1. I’m trying to get information on Oakmount Mansions in Oakmount avenue/Westbourne crescent.
    I am interested in when they were built and if the existing building is the original mansion or a rebuild

    • As far as I know it was probably mid to late twenties and is original (somewhat rebuilt after the war damage though).
