A four-bedroom detached house on a huge plot in Digswell is on the market for £1.4 million.
The property, located on Harmer Green Lane, is just a short walk from Welwyn North station.
It is set in three-quarters of an acre of land and has been described as a "charming family home" by estate agents Bryan Bishop & Partners.
The house has four bedrooms, one bathroom and three reception rooms.
The estate agents said that the property has "a huge number of development scenarios" due to the size of the plot and its location.
They added: "Of course, the house as it stands is a practical and lovely family home, which would easily and readily accept some upgrading to bring it swiftly up to the finest modern standards, but it displays some obvious extension routes that would transform the living space, subject to planning consent."
The front door opens into a lobby which leads into the main hallway.
From here, doors lead into the living room, kitchen, family room, and guest cloakroom.
The living room is described as "fabulous" and is "bathed in natural light" from the large windows that overlook the garden.
It is more than 20 feet in length and 16 feet wide.
The dining room is located between the living room and the kitchen and has double doors that open onto the rear garden.
The kitchen is described as "clean" and "smart" and has doors leading to the dining room, hallway, and rear garden.
Off the kitchen is a boiler room and a large utility/laundry room.
Completing the ground floor is a large family room with a huge picture window to the front.
The estate agents added: "Again, offering a multitude of potential uses, at over eighteen feet in length this room would prove extremely capable as a games room, TV room, reading room/library, gym, craft workshop or a comprehensive work from home facility readily accommodating multiple workstations."
Upstairs, the hallway leads to each of the four bedrooms and the family bathroom.
Three of the bedrooms have fitted cupboards and the other has a private walk-in dressing room, which is currently being used as a home office.
The house is surrounded by mature hedging, providing privacy.
A long driveway leads to a parking area at the front of the house, as well as a double garage.
To the rear of the garage is a large workshop area with double doors into the rear garden.
The rear of the house opens onto the patio from the dining room and kitchen.
The majority of the grounds are laid to lawn, with some trees.
The estate agents said: "Despite the substantial garden area to the front, the house is positioned perfectly in the front third of the 3/4 acre rectangular plot, giving easy access to the rear space for the development of additional properties, whilst also allowing plenty of free area around the existing house to expand the upper floor as well as the original footprint.
"This property, located where it is and surrounded by other substantial properties that have themselves been expanded and where additional infill homes have been built, represents one of the finest opportunities for development we have seen for a very long time."
