Sometimes a householder was allowed to encroach upon the road, and in Riley's _Memorials_ we find patents of leave for building a _hautpas_, that is, a room or floor raised on pillars and extending into the street. Such a grant was made to Sir Robert Knolles and his wife Constance in the year 1381. Penthouses are frequently mentioned in the city ordinances, and they were to be at least 9 feet in height, so as to allow of people riding beneath. It was enacted, for the benefit of landlords, that penthouses once fastened by iron nails or wooden pegs to the timber framework of the house should be deemed not removable, but fixtures, part and parcel of the freehold.[31] Shops were open to the weather, and the need of a better place of protection for certain property was felt, which caused the erection of selds--sheds or warehouses--which were let out in small compartments for the storing of cupboards or chests. These served in their day the purpose fulfilled in ours by Safe Deposit Companies. Several of these selds are mentioned in the city books; thus there was the Tanner's Seld, in or near St. Lawrence Lane, and Winchester Seld, near the Woolmarket of Woolchurch, also another in Thames Street. In the Hustings Roll we hear of the 'Great Seld of Roysia de Coventre in the Mercery,' known as the Great or Broad Seld. In 1311 we find tenants surrendering to Roysia, wife of Henry de Coventre, space for the standing of a certain chest in the seld called 'La Broselde,' in the parish of St. Pancras, in the ward of Cheap. Windows are mentioned in the Assize, but glass was only used by the most opulent. The windows of the citizens in the reign of Richard I. were mere apertures, open in the day, crossed, perhaps, by iron stanchions, and closed by wooden shutters at night. Glass is mentioned as one of the regular imports into this country in the reign of Henry III., and in the time of Edward III. glaziers (_verrers_) are mentioned as an established gild.[32] The buildings were constantly improved as time passed, and there is reason to believe that London was much in advance of continental cities as to comfort and cleanliness, in spite of some unflattering pictures that have come down to us. We have reason to believe that the standard idea of Englishmen as to comfort and decency was always higher than that of his neighbours. This point, however, will be more fully considered in the seventh chapter on Sanitation.
