Devonshire House, the latest phase, comprises 17 townhouses, pictured, arranged, Oxbridge-like, around cloisters, quadrangles and formal gardens. Each house has a different layout, with up to four bedrooms and 3,498sq ft of space, plus a lift and Gothic-style architecture including arched windows, vaulted ceilings and ornate stonework. Two of the houses incorporate the original parapets and have vast roof terraces with views across 100 acres of private parkland.
Contemporary interior design works well against the heritage features. The grand dining hall can be hired by residents, who also have a gym, swimming pool and a free shuttle bus to Bushey station, from where trains to Euston take 20 minutes. The homes start at £1,107,889. Call 01923 222 292
