Fenton House, London

National Trust.
This 17th-century merchant’s house has remained largely unaltered during more than 300 yars of continuous occupation. Inside, there are notable collections of furniture, pictures and porcelain. In almost every room stand early keyboard instruments collected by Major Benton Fletcher. The walled garden has terrace walks framing a lawn and sunken brick-paved rose garden. On the other side of a high wall is an orchard and vegetable garden.
The house and contents are well worth a visit, as is the garden. It’s an easy walk up from Hampstead tube station, through some interesting streets. Driving and parking here looks like a no-no.
