This 24,475 square foot mega mansion is under construction at 4939 Manson Court in Dallas, TX.
From my friend John over at North Texas Luxury:
Bryan Wilburn, President of Southwest Risk, owns the lot where this 24,475 sq. foot residence is under completion. Started back in 2009, the huge home features 9 bedrooms, 9 bathrooms, 6 fireplaces and 3 wet bars. The Wilburns are selling their home over at 6138 Norway Road in Dallas for just under $3 Million.
