Paragraph 4

A hereditament or premises shall not be deemed to be used otherwise than wholly for the purposes of a private dwelling or private dwellings by reason of either or both of the following circumstances, that is to say—

(a)

that there is included in the hereditament or premises a garage, outhouse, garden, yard, court, forecourt or other appurtenance which is not used, or not used wholly, for the purposes of a private dwelling ;

(b)

that part of the hereditament or premises, not being such an appurtenance as aforesaid, is used partly for the purposes of a private dwelling or private dwellings and partly for other purposes, unless that part was constructed, or has been adapted, for those other purposes,

or by reason that a person who resides in the hereditament or premises, or in part thereof, is required or permitted to reside there in consequence of his employment or of holding an office.
