Project Challenges

The main challenge was the age of the building and the modifications that been previously carried out. This caused major complications to strengthen the building and enabling a further level to be constructed at roof level.

Another challenge was to build a side extension including basement. This needed to incorporate the existing boundary wall in its construction and was achieved by careful underpinning of the wall and temporary propping works back to the main structure.
