Thank you for responding!
So, my current plan is to spilt the building into roughly four stages, the first starting with the section north of the main road, along the border with KL4, followed by a similar section to the south, then to the east, and finally the west. I chose to do it this way because most of the work that side of KL4 is already done and having a greater sense of completeness there would be nice.
On the two Unesco builds along the main road, for the auction hall, I have two ideas in mind that really depends on what I think will work best when I get around to plotting everything. The first idea is to expand the square that is already there and to adjust it to fit the new road, and the other is to move the square, with the auction hall, to the south, closer to the market hall. Though I have quite a few ideas on how to make it work, I have concerns that a square, especially one that is not very large, would look awkward on a large, straight road like this. If I cant make the square work in its current location, I plan on moving it further south, away from the main road. The inn, which is in the same square as the auction hall, will continue to be in the same square.
On the silent sisters complex, only a tiny sliver of it is actually within KL13, with a wall of the garden poking one block onto where the new road is planned, as far as I am concerned, exactly how this building is moved/adjusted is up to whomever applies for KL12. As it currently stands, the building is not in the way of anything, and poses no problem to KL13's progress. Its location may prove to be somewhat visually awkward once everything is said and done, but again I do not think that is up to me to say.
After a lot of thought and asking others for their take, I think it would be for the best if the street of silk was cut out KL13. I do not think it would be fair for someone who would only do a small section of the street of silk to set precedent on how it is to be updated, that should either be left to whomever applies for KL6, or be publicly discussed in its own forum thread by the community at large.
The special builds in KL13 that will be open for testing are the dyeing complex, the two unesco inns, one on the square and one along the road between dragonsquare and cobblers square, a city guard building, the auction hall, and a large lychyard. It is possible that I will end up doing the dyeing complex and/or the lychyard myself, or cooping with another builder.
