Gloucester Prison will be sold to City and Country, it was announced yesterday.

City and Country, a development group specialising in the conversion of listed and historic buildings for residential and commercial uses, has bought the site along with Dorchester, Kingston and Shepton Mallet prisons.

The firm is working on its development plans which are likely to be mixed use schemes including residential development with assisted living units, complementary retail and social amenity areas.

Here are some examples of current and past developments by City and Country.

Bristol General Hospital

Bristol General Hospital dates back from the early 1830s. The hospital fully opened in 1858 and was an extremely grand building, which served the local community for 150 years before in closed in 2012.

City and Country purchased the site and is currently developing a mixed-use scheme comprising 205 luxury residential units, commercial floorspace and on-site parking.

The site houses a number of landmark listed buildings, which occupy Bristol’s harbourside.

Balls Park, Hertford

Set among 63 acres of picturesque parkland, the Grade I Listed Balls Park Mansion House and surrounding buildings have been converted in to a collection of stunning apartments delightful detached homes.

Having served as an education establishment for many years the beautiful buildings were falling into disrepair and became unsustainable to maintain. In 2001 City and Country purchased the estate and began the careful and expert work to restore all the historical buildings to their former 1638 glory.

Working with the original period features each home was designed to ensure none of the historic beauty was lost in the conversion process. Whilst externally the buildings were brought back to life with stonework cleaned, replaced where necessary and sash cord windows restored. Also communal areas such as the main Vestibule were kept for public use for all residence to enjoy.

Gilston Park House, Hertfordshire

Gilston Park House is an outstanding Victorian Country House situated in an elevated position with views across the English countryside.

The building was originally constructed in 1852 in a Tudor style with Gothic touches, subsequently altered and extended in 1903, in recent years it had become the offices of a large pharmaceutical company. City Country obtained permission for conversion into 7 houses and 7 apartments.

When work was nearing completion on the first apartment an electrical fault started a catastrophic fire on the evening of 12th January 2000 and approximately half of the second floor and the roof was lost. What began as a relatively straightforward conversion project became a massive renovation project. Specialist equipment was brought in and used to save and retain all of the important historic features. It took months of work with meticulous attention to detail to successfully reinstate not only the fire damaged second floor and roof but also the extensive water damaged beautifully carved wooden panelling and ceilings in the principal reception rooms and communal areas.

Old Saint Michaels, Braintree

Old Saint Michaels offers apartments, homes and boutique offices from a collection of Grade II Listed Victorian buildings set in eye-catching landscaped courtyard garden

Old Saint Michaels was built as a Union workhouse in 1837-8 by Royston architects, William Nash.

City and Country has reinvigorated the Old Saint Michaels entrance by restoring the original gates and adding planting appropriate to the formal entrance. It has also created rich and tranquil car-free landscaped courtyards replete with an array of established plants and trees.
