when a single family dwelling house is being converted to a HMO do we class it as being rooms for residential purposes (therefore a change of use) or not?
do we apply regulation B1,2,3&5 alone (being a material alteration) or should we consider regulation E3 as we would in a material change of use?

how about this one. the definition of a room for residential purposes within the building regulations is "a room or suite of rooms which is not a dwelling house or flat used by one or more persons to live and sleep. it must also be separated from the rest of the building by a door designed to be locked, and not to be occupied as a single household" numbers are not mentioned. it also states that a dwelling house is a building occupied by a single family unit. however guidance in ADB in both volumes states that guidance within may be used for HMO's providing they are occupied by no more than 6 people.
in my mind if a HMO occupied by 6 or less on a single tenancy agreement that has no lockable doors can be treated as a dwelling house. separate tenancy agreements and or locks on doors would constitute residential rooms?

is then a building or part of a building that does form a HMO as per the housing act automatically constitute as being a room for residential purposes?
