 The budget for the works was £ 420 @,@ 000 , with initial work focused on stabilising the foundations and lower masonry . Much of this was achieved through the injection of stabilising materials into the foundations , which needed time to cure and solidify . Works then progressed to the walls and roof , and finally the decorative embellishments . Today , while part of the Orangery is a dedicated café , the rest is an international education centre of excellence for the Trust , training new craftsmen and restoration specialists .
