Peakholme

Summary
Peakholme is the country home of Sir Hubert and Lady Armstrong in Think of England. It is fictionally located near Newcastle, quite a ride from the train station.

The house is described in Chapter One:"'Sir Hubert [..] had had Peakholme built to his own specifications some fifteen years ago. It had been an extraordinarily modern creation at that time, equipped with the very latest innovations, with running water in all the bathrooms, heated by hot-water radiators and illuminated throughout by electricity from his own hydroelectric generator.'"

Real or Fictional?
Peakholme is based on the estate Cragside in Northumberland, England.
