wondering if anyone has experience with making a room
out of attics that contain cross ties (bracing) between
the rafters on opposite sides.

i have an attic that i'm considering getting estimates
from engineers/architects to convert into livable space.

was curious how much work is involved in removing the
cross ties (that are now about 5 feet above the floor
joists, every 4 feet or so).

what's the engineering or framing principle to remove
them and not affect the rafters transmitting their load
to the bearing walls?

the rafters are squared up against a ridge beam.

i'd also have to relocate the AC unit & ducting, also
beef up the joists.

the main concern was the cross ties/bracing.

has anyone done any projects like this ?
