One of the UK's grandest country estates has come to the market as a refurbished and rebuilt new-homes development. Grade I listed Balls Park is on the outskirts of Hertford. Developer City & Country Group is transforming the mansion (built around 1648) and the grade II listed coach house and stables (1902) into 40 apartments.

Prospective purchasers can now see the show apartment in the Stables. It comprises 12 one- and two-bedroom homes, which will be ready for occupation by Christmas.

Balls Park is set in 63 acres of picturesque grade II listed parkland, which is on the English Heritage register of historic parks and gardens. Each of the homes at the Stables will have access to the private gardens and parkland.

The estate is believed to have inspired parts of Jane Austen's Pride and Prejudice and was used as a location for the films The Young Victoria, Amazing Grace and The Golden Compass, as well as several television series, including Foyle's War and Bleak House.

Properties in the Stables include restored sash windows, as well as other original features. The apartments have wool carpets, porcelain floor tiles and either oak boards or restored original floorboards. Kitchens are equipped with stainless steel appliances.

Helen Moore, City & Country Group residential managing director, says: "Through our commitment to the preservation and conservation of historic and listed buildings, we have ensured that this magnificent house and estate is being restored to its former glory and beyond. We have carefully retained intricate details, bringing together old and new to create stunning homes and a unique living experience.

"The Stables is the first part of this incredibly exciting development to launch and blends classic architecture with contemporary interiors. There really is nothing else like it."

Prices start from £237,500 for a one-bedroom apartment and £365,000 for a two-bedroom apartment.
