Redevelopment of the site for the construction of student accommodation of 295 bedrooms, and associated works.
The site is located within the historic core of Gloucester and includes part of the Roman fort, part of the Roman town of Glevum, evidence for Anglo-Saxon occupation and of the 11th century Norman castle at Gloucester. Two areas of the site form part of the scheduled monument of Glevum Roman colonia. The site had been vacant and undeveloped since the 1990s.
Prior to the determination of this planning application a desk-based assessment, followed by a trial trench evaluation supported by a watching brief on geotechnical investigations, were carried out and a deposit model produced.
The evaluation indicated that much of the site contained well preserved and deeply stratified urban archaeological remains of national importance, including evidence of the rampart and probable wall of the Roman defences, several Roman buildings (probably town houses), and Anglo-Saxon and medieval deposits including ditch deposits that may be part of the 11th century castle.
This information enabled the developer, during the determination period, to redesign their scheme largely to avoid archaeological impacts (in accordance with Historic England piling and preservation in situ guidance).
The result was that the overall cost of archaeological mitigation was reduced and the scheme was able to achieve very high levels of preservation in situ (the impact of piling within the building footprint is often less than 1%). This is a very sustainable approach that should be reproduceable elsewhere in Gloucester city.
The development was given planning permission with pre-commencement planning conditions covering:
- Archaeological investigation
- Public engagement
- Prior approval of foundations, and all groundworks in order to minimise impact
There was still a need for some archaeological excavation in advance of development, and a watching brief during development, as some impacts could not be avoided. But, given the scale of the development and the importance of the archaeology, these were limited in scale.
Planning permission included a condition to secure a programme of public engagement.
