Hemsby Chalet removal

Hemsby has been in the news for the last few months as storms washed away the dunes where a number of people had lived for many years, in an area called 'The Marrams', which is a give away to their location of course (shared some ideas on the importance of marram grass and sand dunes). Seven dangerous houses had to be removed.
We have the North Norfolk coast as our Distinctive Landscapes case study for OCR B GCSE Geography.
Hemsby is an area I've visited, and went down to the area following the 2013 storm surge too.

There is a new coastal road being constructed, and there may be some new chalets appearing further back from the edge as time passes.
Should these houses be given protection?
There is a new BBC Teach Big Issues programme which asks that question, with regard to Happisburgh.
