High St. Pondsmeade
This long rectangular red brick building with a plain tile roof has projecting north-west and south-east wings was built in the early 19th century as a factory according to the listed buildings survey. There is a suggestion that this building was used in the watercress business of T. Sansom. Here, cress was packed and the wide entrance was used by carts taking the crop to the station. It is two storeys high with brick eaves. On the front of the building the earlier three part carriage doorway with a wooden lintels can easily be seen and this has led to the belief that it was the original coach house for Redbourn house.
