Being a seasoned woodworker by hobby and trade don,t take too much offense to Tpreaves comments. But do take them with clear thought that he is correct. The machinery and knowledge to do what you descibe and not knowing basic carpentry would be a stretch at best. And living in a NY apartment would probably require doing it with smaller hand tools which although can be done requires a higher skill level yet again. In the end it would be far cheaper to have someone locally and skilled to build it for you.
