GV II*

Outbuilding, c1810, red brick with slate roof. First floor square
openings each end of west front, ground floor double doors, larger
double doors, door with cambered head and window to right Interior
has remarkable patent fireproof roof of wrought-iron strip or 'hoop
iron' as used in cooperage. Closely spaced grid of vertical and
horizontal strips to roof slopes, the strips notched together and
secured by patent metal clips. Densely spaced trussing of similar
strips, tie pieces rising to pendant strips hanging from ridge, the
tie pieces overlaid longitudinally with notched strips. The system
was the invention of Mr. Pearsall of Willsbridge, near Bristol, and
trade particulars of 1812 issued in connection with a large roof
erected in the East India Docks, London, mention five roofs already
erected in the Bristol region, of which this is the only apparent
survivor. An exceptional example of early use of iron in roof
construction.
