Later, in 1784, a large new house was built for the Dockyard Commissioner. Unusually for the time it was designed by a civilian architect (Samuel Wyatt, with Thomas Telford as clerk-of-works); most other dockyard buildings were designed in-house. The dockyard chapel, built eighty years earlier, was demolished to make way for the new Commissioner's house and a new chapel was built nearby. After the old Commissioner's House had been demolished, four identical quadrangular buildings were built, flanking the timber ground east of the Basin; as well as providing storage space, they accommodated workshops for a variety of trades, including joiners, wheelwrights, wood-carvers, capstan-makers and various other craftsmen. At the same time a set of offices for the senior officers of the yard was built overlooking the docks and basin; it continues to provide office space to this day.
