Formerly known as Frognal Lodge, the nine-bedroomed estate last comprises a pair of semi-detached Grade II listed Georgian houses that were combined to form a grand single dwelling.
Also nestled in the grounds is the The Folly, a two-bedroom coach house accessed via Church Row, which has a separate garage, a store and off-street parking for two cars.
The entire estate is on the market for the first time since 1931 through estate agent Goldschmidt and Howland, who sold it to its current owners back then.
Director Philip Green called the house “iconic”. He said: “It’s absolutely unbelievable. The family brought in the original brochure when they bought it from our company, because we’ve been here since 1888.
“It’s the most hidden, unbelievable home. I’ve walked up and down Church Row for 40 years, I never knew it existed.”
In one part of the lodge, a discreet front door opens into a reception hall. This in turn leads to a drawing room with a fireplace and french doors to the terrace and gardens.
A large kitchen opens on to the garden and also through to an orangery with mature vines and spectacular views.
A utility room has access to two cellars and guest cloakroom.
A wide sweeping staircase leads to the first floor with its principal bedroom, with a walk-in wardrobe and en-suite shower room.
There are four additional bedrooms, a family bathroom and separate cloakroom.
The other part of the lodge has a private entrance leading to a small courtyard, from which a door opens to the entrance hall, and a reception room with garden views.
There is also a kitchen, pantry, study, guest cloakroom, workshop and large utility room.
As well as a principal bedroom with dressing room and en-suite shower room on the first floor, there are also three further bedrooms, a family bathroom and a separate staircase allowing direct access to the garden.
Mr Green added: “It’s got .65 of an acre, in the middle of the village. Many many years ago the owner used to open the gardens up for a garden spectacular but they’re moving because really the house is too big for them and they are downsizing, but it’s like a mini estate in the heart of Hampstead.”
The landscaped lawns are surrounded by herbaceous borders, ornamental trees and shrubs, with many rare plants hidden behind a high wall.
A tennis lawn once formed the central garden, and could be reinstated by a new owner.
