The hip void will be formed in a way similar to that illustrated in Fig. 3.7, and in most
cases the purlins will be supported from a load bearing wall below. However, it is not un-
common to find the purlins actually giving little support to rafters except to bind them to-
gether; in such instances the rafters are actually the only support for the roof often using
the hip rafters as main supporting members. To provide an adequate width to the loft room
it may be necessary to consider removal of some of the purlins in these traditionally con-
structed roofs and this will be dealt with later in Chapter 11, 'Solutions'.
