[Avodah] Yurt for a Sukkah

[Moshe Y. Gluck]

R'n SLB:
A friend is going to be taking a course during Sukkot. The dwellings there
are a dome and a yurt (http://en.wikipedia.org/wiki/Yurt).

They asked if they could use the yurt for a Sukkah, and if not - what would
they have to do to make it kosher?
--------------------

Doesn't look like they can, unless they alter it enough that it won't be a
yurt anymore! I'm no expert, but after reading the wikipedia article, it
seems that they would have to - at minimum - remove the roof (which seems to
be one big piece of felt, which also covers the walls), which would reduce
its structural integrity, and replace it with Schach. But it would also
depend on how the particular yurt is constructed, something which there
seems to be quite a few variations on. They could also remove part of the
roof, enough so that there is 7 x 7 square of tefachim enclosed by walls,
but then they'd have to worry about Dofen Akumah. Might be best if they just
bring their own sukkah along...
