Mark,
go to the following site, http://nd.durham.gov.uk/recordoffice/usp.nsf/pws/Durham+Record+Office+-+Maps+-+About+Interactive+Maps+GIS.
Go to maps, then "launch the GIS now", zoom in on the area [Thorpe Larches], below the map is a box labelled "historical maps", click it and you will be given a choice [you may have to zoom in before a choice is given]of dates. Its not as accurate as it could be, as no development is shown at the larches before 1951. The Larches was built well before this.

Dear All

I grew up in Thorpe Larches and I was given to understand that one of the first dwellings to be built was at the bottom of our track - still standing and called Moontree Cottage. Seems there may be a connection.
