Elon Musk, known for selling his houses, plans to build a mega house in Texas 

Musk purchased a horse farm near the Colorado River and Tesla's Austin Gigafactory 

He considered buying a house in Austin but opted to build his own due to cost concerns 

Musk discussed the project with architect Norman Foster, envisioning a unique design 

The house would resemble "a shard of glass coming out of the lake 

Musk's Boring Company considered creating a tunnel from the house to Tesla's factory 

Tesla launched an internal probe into this project, involving glass house plans 

The project raised scrutiny within the company and led to investigations by the DOJ and SEC 

Musk denied reports of building a house, but the status of the project remains unclear 

Musk sought to create a central home for his expanding family, with 11 known children
