“The metal covering was another factor that had come up in the
course of our conversations with English Heritage.”

After all their careful groundwork at the design phase, Debbie and
Laurence’s extension plans achieved planning permission and listed
building consent without any issues. “We submitted a supporting
statement that outlined how we’d adapted our plans based on the
advice we received from English Heritage,” says Laurence. “It was

and finished with a standing seam zinc covering.

One of the key construction challenges revolved around uniting
