St Mary’s Works is a city centre brownfield site measuring approximately 1.1 hectares which contains two Grade I Listed medieval churches and their churchyards, St Mary’s Church to the south fronting St Marys Plain and St Martin’s Church to the North fronting Oak Street and St Martins Lane. The locally listed early 20C former Sexton, Son & Everard Ltd shoe factory lines the east side of Oak Street and addresses St Marys Plain to the south. The remainder of the site is occupied by a series of 20th century offices, workshops and warehouses.
There is a high concentration of heritage within and in proximity to the site. Designated heritage assets include listed buildings and the city centre conservation area; non-designated heritage assets include locally listed buildings and the area of main archaeological interest, and items as yet unidentified.
There are further heritage assets within close proximity of the site, which may also be impacted by proposed development . Designated heritage assets include listed buildings at Pykerells House on Rosemarys Lane Listed Grade II*, 47 & 49 St Martins Lane, 57, 59 & 61 Duke Street, 67 Duke Street and 69 -89 Duke Street Listed Grade II and locally listed buildings include the Zoar Baptist Chapel St Marys Plain, St Marys School Hall and 43, 45, 47-49, 51- 55 Duke Street. Depend upon the scale of any proposals, further heritage assets may also be affected. A comprehensive Heritage statement and heritage impact assessment will be required in support of any proposals.
The site is located within the City Centre Conservation Area, with the majority of the site and its heritage assets located in the ‘Colegate Character Area’ and the north-eastern corner of the site occupied by a 20C office building being located in the ‘Anglia Square Character Area’.
Mature trees within the churchyards are protected by conservation area status.
The site is situated within the Area of Main Archaeological Interest; this area offers potential to reveal more about the history of the early City. It is likely that the archaeological potential across the whole site will be of interest. Archaeological investigation below any areas of construction or altering of the ground will likely be required to assist in the understanding of the City.
The site is situated in a prominent location within the Northern City Centre strategic regeneration area, as defined in policy 7.1 of this plan, and is likely to accommodate a minimum of 150 homes. The site was previously allocated in the now expired Northern City Centre Area Action Plan for mixed use development and benefits from extant outline consent for redevelopment including around 151 residential units, office floor space, and a hotel, accordingly the principle of development is accepted
Development of the site must address a number of constraints including its location in the City Centre Conservation Area and Area of Main Archaeological Interest, the relationship with neighbouring statutory and locally listed buildings and gateway to the city, site ground conditions, possible contamination, risk of flooding from Flood zone 2 and surface water flooding. A noise impact assessment and air quality assessment will be required, and the development must be designed to mitigate the impact of noise from the main road.
