Hi, Edenstrauss. thanks very much for kindly sharing your experience and info with me. i eventually got the job done by Mix Box Interior Pte Ltd. (Contact person Mr Alex 9655 8838) and i must say i was very impressed by the good service they provided. as you noted, my kitchen doorway was much taller and wider than normal doors. so Alex suggested constructing "U Box pelmets" (hollow false wall made of gypsum board) to lower and narrow the passageway. (this cost $80 + $50). They suggested I use the 'PD Door' which slides into itself, and then swings away, and it has no roller guides on the floor as it hangs. The quotation for the PD door was $400. So the total was $530. We were very pleased with the results. perhaps i'll upload some pix of the final product soon. best regards, Dina
