A Representative Tea Hut

Note 1The secondary roof at the end of the hut.  We will construct one of thse using the lap board design previously discussed.  This secondary roof should be hinged in such a way that it folds down over the end wall during storage.  This emulates Heian period shutters.  A detachable secondary roof is an alternative to this approach. 
Note 2The skirting beneath foor level.  If possible, I would like to emulate this type of skirting at least on the eight foot ends which donot have wheel wells do deal with.
Note 3The plaster color in this pictureis typical of tea huts.  We should try to emulate it.

Exterior End Posts

Note 4It should be possible to lay secondary ridge beams to either side of the primary ridge beam.  These would have to be 1 1/4 x 4 stock milled to approximately 3 x 1.











Note. This wall design assumes 1/4" interior plywood. Dimensions in the floor plan may need to be modified to accomodate 1/2" interior plywood.

Dupont Stucco Wrap will provide a wall surface which can be painted or stuccoed without the plywood texture showing through.  Du Pont recommends using Stucco Wrap as part of a two layer system for exterior walls in severe weather environments.
