Postal addresses are not necessarily very detailed. It varies, but might depend on the location, dates and the population. Many addresses on censuses are simply, for example, "High Street" and then the town name. Depending on the town or village there can be pages of people with the same address of "High Street".
There have been numerous threads about odd addresses. One of mine lived "above the barn" in one census.
Also keep in mind that the census address is one night in ten years, so probably not wise to jump to any conclusions about addresses.
No censuses specifically show "type of accomodation" though with some it is included in their address. The 1911 census asks for "number of rooms" in the dwelling. That is on the bottom of the page. You could have a look at this number to get an indication of the size of the house and wealth of the family.
