New construction in Pinellas County beach towns

[Bruce Harney]

I am considering buying land with house on it, scraping it and building new in Madeira Beach or Redington Beach area (outside of Tampa).  I've talked to a few builders and general cost has been in the $175 - $200 psf range.  In order for this to be feasible for me it has to be under $140 psf.  Anyone know any good builders who can do this or have suggestions on how to proceed?  I've thought about trying to hire all the subcontractors and overseeing it myself but that would be a major project.  I've overseen renovations but never new construction and I work a full time job so not sure if I have the time.

I realize the cost psf varies greatly depending on finishes and this being in a flood zone requires the structure to be elevated and pilings every 10 feet that go 20-30 feet deep.  If it's not realistic to build about a 2,500 sf elevated house with high quality finishes for under $140 psf then I'll move on to plan B.

Any suggestions will be greatly appreciated.
