Custom home build in Houston

[Dave Passey]

I have a house that can get off of the "Wick" streets in Houston. It is just south of Memorial Dr and west of Voss Rd. These houses are super expensive. The house that I can get is about 3700sf and was flooded in Hurricane Harvey. From what I see in the area, there are a lot of houses that have been torn down in order to build some massive 9000sf houses that are selling in the $4M range. 

The question I have is Who knows a builder that can handle a project like that or would be willing to spearhead it. I don't know people that do work in that price range and wanted to see if anyone could help me out.
