Expanding Strip mall

[Laxman Molugu]

Hello RE gurus,

I have a small strip mall with 3 stores with 4000 sft on 2.5 Acre land with 25 parking spots, I am planning to add more stores (4 more stores with 6000 sqft ), I had discussed with the town mayor and he is in full support on this project as their town planner thinks the lot is underutilized. Also, we did some analysis on the market, looks like there is a good demand for the location.

I am looking for some help, where to start from here? what kind of structure recommended for better pricing(wood/masonry/metal), any recommendation for Architects/Engineer for the planning for getting township approvals. And the most important what is the price range for sqft?

Location is Sussex County, Northern NJ

Thanks,

Laxman
