Nah...not necessarily, the "house" was obviously an old church at one point, plenty of room to house their engineers. Their office looks much older then the surrounding residences and businesses so it's probably a historical site....definitely a trendy place for an office, you see it all the time in the US.
still not sold that this is a scam. I distrust the group that you are associating yourself with. I think this is a shall company that is starting to make moves. Very simple really
