Surveys show that the foundations of the existing building are in good condition and have spare structural capacity. Reuse of these below ground structures will:

 Make good use of the embodied carbon they contain

 Reduce the construction programme

 Minimise groundworks, the noisiest and most disruptive part of the construction process

Despite a higher carbon footprint than retrofit, redeveloping the structure above ground will:#

 Provide better internal and external spaces for building users benefiting wellbeing

 Be more flexible and adaptable for future workspace trends and needs

 Allow for more public space at ground floor

 Provide new uses and facilities

 Be more energy efficient in use
