I agree Alan - it could very well be a Terrace.
It can help to narrow down an address if you follow the enumerator’s route on a census, to narrow down the approximate location. You may need to check numerous streets in the vicinity and if lucky locate a landmark that still exists today, which can be of help.
If Alan’s theory is correct and the houses are still standing, look on google maps - sometimes the name of the terrace or row of houses is marked on a nameplate. I’ve seen this a number of times.
If you haven’t already done so, locate them on other censuses in case they are at the same address, keeping in mind that if this is a terrace, other censuses may give the street name rather than the terrace name, so you should check surrounding areas to clarify.
