From A Wiki of Ice and Fire
The Mouse House is a palatial manse overlooking the harbor of Hull on Driftmark.
Marilda of Hull, the mother of Ser Addam Velaryon and Lord Alyn Oakenfist, constructed her manse during the Lysene Spring. Mushroom named the building "Mouse House" because Mouse was Marilda's nickname.
