Thanks a lot for all the support! You are encouraging me to continue the work.
So, now the second phase of my first industrial complex.
A month later the same building received the annex comprising a staff canteen and a big billboard with a company name on the roof edge. The name is real, Audio-technica Corporation (est. 1962 in Shinjuku, Tokyo) plays it's important role as an audio equipment supplier. So my small complex could play a role of a research laboratory for the Company.
