Hannover Terrace, NW1

This traditional butterfly roof on a mews house in Regents Park was leaking heavily and not in keeping with listed building consent.

A new valley gutter was constructed, with sufficiently sized ventilated bays either side, ready to receive code 5 lead, followed by Welsh Penrhyn slate.

The parapet walls have been re-rendered with a lime mortar and covered with a lead capping to help prevent future saturation.

It’s a lot of pressure to work in London but also a privilege.
