A set of 3 warehouses by the River Witham in the centre of Boston were demolished. The site is near the new bridge over the river. Before demolition Boston Archaeological Group made a survey of as many parts of the buildings as was possible in the available time. All 3 warehouses were each a complete building in themselves, but there were several lean-tos and shelters on the perimeter. 1. Wooden warehouse. The warehouse nearest to the river was constructed entirely of timber. It consisted of 5 storeys each with shuttered windows with regular intervals and the 3 centre storeys on the riverside had hoist doors. The walls were of weather-boarding and it had a hipped slate roof. The four upper floors projected beyond the ground floor on the riverside only. Originally the building was on piles and it was noted that at high tide the river would have flooded beneath it. The height to eaves was 37 feet 4 inches and approximately 49 feet to roof ridge. 2. Middle warehouse. A central warehouse constructed of brick abutted the wooden one and consisted of 4 storeys. These storeys were not in alignment with the storeys in the wooden warehouse, although there was access between them at each level. This access was through the hoist door openings, which presumably overlooked the river before the wooden warehouse was built. The mansard slate roof gave extra floor space. There were glazed casement windows on both the north and south sides - the 4th storey were dormer type windows. The walls were tapered, the thickness of the walls on the lowest storey being about 18 inches. The first 3 storeys were each divided into 2 rooms. A 61 feet by 3 feet square chimney stack was towards the north side of the building, but had been removed. 3. Front warehouse. The third warehouse, fronting on to South Square was at right angles to the middle warehouse. A 5 storied brick building with a slate roof. Height to eaves 41 feet 11 inches, height to ridge 50 feet 9 inches. There were 14 glazed windows on the east and west sides on each floor, making the rooms extremely light. The two upper floors were all casement windows, but the lower ones had some sash windows inserted. Again the walls were progressively thinner, as was the chimney stack abutting the north wall. This made the rooms in the fifth storey appreciably wider than in the lowest storey. The only hoist doorway was in the centre of the first floor at the front of the building. Access to the upper floors could only be gained from the middle warehouse. Height to eaves, 41 feet 11 inches - to ridge 50 feet 9 inches.{1}
