Full Gut Reno- 3 family house- Queens

Hello- I am looking into a full gut reno on my frame house, the house is detached on both sides and the foot print is 20x60(about), lot is about 20x100, no walkway on either side. I am in the very early stages, have lots of research to do on financing, architects and potential design (within the R5-d zone).

Hello- I am looking into a full gut reno on my frame house, the house is detached on both sides and the foot print is 20x60(about), lot is about 20x100, no walkway on either side. I am in the very early stages, have lots of research to do on financing, architects and potential design (within the R5-d zone). I am leaning towards a gut reno- tear down the walls, floors, move walls/kitchen/bathrrom and rooms, upgrade electrical wires/water+gas pipes and try to upgrade modernize where it would make sense, sister/reinforce beams and stilts and possibly extend the home in the rear from level 1 through 3. and, maybe add a greenspace sort of roof (not even sure if this would be do-able) it is a lot of work, I was hoping someone here has recently done something similar on the forum and could point me in the right direction in terms of recommendation (architect, construction companies to consider) and other points to take into consideration. Lastly, I know cost is a huge variable depending on many factors... I am not looking to do anything high end, aiming to be in the middle ground of $$$. What do you think a ballpark range would cost for this in Queens? [less]
