Timber roof, church interior and a double-ditch fortress plan
Roof framing, an arcaded interior, small plans and a fortress of double moats
The sheet gathers architectural studies: a timber hip-roof drawn both in perspective and as a braced square plan, an arcaded loggia or church interior at left, three small building plans, and a portal whose latch is noted. At the lower centre a fortress plan explains a system of double ditches, where spurs running from the main wall to the outer rampart (the 'garland') act both as buttresses and as positions from which that rampart can still be defended should the main wall fall. A short annotation beside the small arched doorway at left does not appear in the given transcription.

Timber hip-roof in perspective and plan
A wooden roof is shown twice: once as a three-dimensional hipped framework of rafters and tie-beams, and once as a square plan crossed by diagonal braces. The paired views let the carpentry of the covering be read both from above and in the round.
Arcaded church interior in perspective
At the left an arcaded loggia or church interior is drawn in perspective, its bays framed by piers and a coffered barrel vault receding toward the viewer. It reads as a study of the play of arches and light within a covered space.
Three small building plans
Three small ground plans are set out at the right of the sheet, each sketching a compact centralized scheme. They function as thumbnail alternatives beside the larger perspective studies.
Portal with its door latch
A portal is drawn and annotated with a note on the latch that holds the door. The detail records how the gate is fastened within its frame.
Fortress with double ditches and defensive spurs
The fortress plan sets out a scheme of double ditches. The spurs that run from the main wall to the outer rampart serve two purposes: they act as buttresses, and from them one can still defend the level of the rampart even if the main wall has been brought to the ground.
