[MassHistPres] carriage shed framing

[Judy Markland]

In Whately, carpenters stabilizing a the only remaining two bays of a 
church carriage shed believed to date from the 1840's discovered that it 
was built with an unusual tipped frame structure.  The center and main 
load-bearing posts, which are set well back from the overhanging front 
roof, were built - not perpendicular to the ground as would be expected - 
but pitched at about a 10 degree angle to the rear.  All the other framing 
members were carefully built to support this tilt.  (If you email me, I can 
send a diagram that makes this clearer.)

Similar framing has been found in a carriage shed built in Northfield about 
twenty years later.

Does anyone know of other examples or the reason for this design?
