Bob Simpson Adding Onto His 13,910 Sq. Foot Mega Mansion in Montserrat

Former Founder and CEO of XTO Energy Bob Simpson lives in this incredulous 13,910 sq. foot mega mansion in the community of Montserrat in southwest Fort Worth.  The 2006 built home boasts a 4 car garage, porte cochere, pool, and an appraised value of $3,780,000.  New aerial images show a large extension under construction on Simpson's estate.  I guess 13,910 sq. feet just isn't enough!  Can't wait to see the finished product.  Here is an image of the front facade of the home and then the aerial image showing construction.

Thanks for reading,
