We have commenced and extension to a dentists surgery in Derby. Works involve constructing an additional story on top of the existing property and the formation of a new roof strucuture. The dentists surgery is to remain operational throughout the construction process. In order to not interrupt the surgery's operations we have constructed a roof tent out of scaffolding, this will in keep the building weather tight and enable works to continue whilst also allowing the surgery to remain open and unaffected by our works.
