I've not heard of Commercial Buildings but if they were in Stoke he would probably be buried at St Peter Ad Vincula in Stoke. If the buildings were actually in Shelton, he could have been nuried at St Mark's in Shelton.
Update: I've just found this:
Penkhull also possesses several groups of workers' houses of a slightly later period, including those built by Josiah Spode II (d. 1827) (fn. 200) and those in Penkhull New Road known as 'Commercial Buildings'.

If these are the correct buildings, he would have most likely been buried at St Peter Ad Vinula.
