Although he was rarely in London, Edward I undertook an expensive remodelling of the Tower, costing £21,000 between 1275 and 1285, over double that spent on the castle during the whole of Henry III's reign.
Kuigi Edward I viibis harva Londonis, võttis ta ette kuluka Toweri ümber kujundamise projekti, mis aastatel 1275–1285 maksis 21 000 naela – rohkem kui pool rahast, mis kulus lossile kogu Henry III valitsusajal.
