If you’re planning to build a new foundation PLEASE look somewhere else! Our experience with Space Down Under and with its owner Michael Musumechi has been an unmitigated disaster, and Mr. Musumechi is perhaps the most despicable, dishonorable, mendacious, and truly frightening human being you will ever encounter. I’m a reasonably normal person – a college professor not usually given to hysteria, but our dealings with Space Down Under has been the most horrifying experience we’ve ever had. Not only did the project end up costing THREE times more than initially quoted, it also took THREE times longer than it was supposed to take and we’ve been subjected to everything from verbal and physical threats from Mr. Musumechi, (who not only has a criminal record but is also certifiably unhinged) to his refusal to finish the project (our house stood on stacks for four months because Mr. Musumechi told us straight into our faces that bringing the house down onto the foundations simply doesn’t pay off for him) to threatening phone calls to the new contractors who took over the job after we fired him. There is no point recounting all the horrors, the levels of deception at every step of the process, and the specific technical as well as personal failings of the company and its owner, but please be aware the Mr. Musumechi is a master manipulator and a truly dangerous human being. Don’t walk away from him – RUN for your life!!! Should you still want to consider him, please do your research, (please be aware that he sometimes gets his permits under a name of another company i.e. Michael A Bruno Construction) contact every homeowner he’s ever worked for (we did that only when things went south and we encountered a family that implored us never to tell him that we talked to them because, and I quote: “we have children”), and in general just stay away. I’ll gladly tell you the whole story and show you stacks of documents, transcripts of conversations with Mr. Musumechi, etc. My email is “[email protected])
