It was built for D. Antonio Vicente Yánez, who in 1771 was appointed Mayor of the Town of El Escorial and of the Royal Site of San Lorenzo. He was also a member of His Majesty's Council, mayor of the Crimen of the Real Chancillería and Lawyer of the Royal Councils.
He is the first Mayor who decided to live permanently in San Lorenzo, despite the obligation he had to reside in El Escorial.
The project dates from 1771 and its architect was Diego Ochoa, assistant to Jaime Marquet at the Royal Coliseum. On 22 April 1773, Juan Esteban certified the completion of the House.
The floor plan is trapezoidal and, in its exterior appearance, the building is one of the most representative of the 18th century. The most important facade faces Gobernador Street, where the entrance door is located, with a moulded granite surround and lateral pilasters supporting two brackets on which an upper wrought-iron balcony rests.
House built for Mr. Antonio Vicente Yánez, Mayor of El Escorial appointed in 1771, who was also a member of the Royal Council, an example of 18th-century civil architecture in the Royal Site.
