“A truly exceptional detached 18th century barn conversion, probably one of the finest examples to come on the market in recent years,” say the agents selling Ponds Barn at Seer Green.

These days, instead of being in the middle of a muddy farmyard the super smart converted barn is surrounded by an immaculate garden amounting to almost an acre on the edge of the village within walking distance of the station.

Franky Viccars who is handling the sale at the Beaconsfield office of The Frost Partnership says the outbuilding is believed to have been built in 1780.

“It’s a fine example of an 18th century barn which has been sympathetically converted. It retains much of its original charm and character,” she says.

Outstanding feature is the 26ft long drawing room that flows into the vaulted sitting room adding a further 16 ft to the length.

The double height entrance hall is equally impressive with sweeping staircase up to the galleried landing.

There are two sets of double doors in the hall – one pair opens onto the dining room which leads to that majestic drawing room and sitting room where there are bi-fold doors onto the garden.

The other pair of double doors take you into the farmhouse sized kitchen/breakfast room.

On the other side the hall, extending from front to back of the barn, is the master suite. The bedroom has double doors onto a courtyard.

Also on the ground floor is a study and downstairs cloakroom.

Upstairs are two further en suite double bedrooms each with a bank of built-in wardrobes.

The guide price is £2m.
