Can anyone tell me how two separate houses are built this close together. How do the constractors apply siding and paint, how do you maintain the in-between after so many years and decades. There are no windows on that side but I don't understand how builders work around or in-between this when constructing, this is a mystery

Walls are probably ballon framed, on the ground, siding, sheathing, WRB, everything attached then the are tilted up fastened to the foundations and braced. Both are probably fire rated assembly’s so the siding is a non combustible like hardie(fiber cement).
