The inspiration came from a similar model featured in a GW Lord of the Rings monthly magazine - the sort that build in to a complete game after about 100 issues! The model construction followed the GW article very closely, with a foam board core on an MDF base.
The stonework is bult from small bricks, larger sections of plastic card and DAS modelling clay. The steps are small tiles given away free with a 'build your own dolls house' publication and the wood on the pyre is balsawood painted and stained before being glued down. Other decorative detail is restricted to small features and bits from my spares box, for example the barrel.
