The Pavilion will house the dressing rooms and club amenities as well as pro- vide accommodation for 550 patrons. The score board and 10 ft. diameter clock are

located at upper terrace level at the southern end of the ground. One of the lisadvantages of the site is that unautho- rised views can be obtained from the sur-

rounding hillsides, This will be partially offset when funds permit the complete covering of the seating terraces.

Economics of Design

The whole scheme was designed with the object of utilising, as much as pos- sible, the material found on the site. All construction work, such as walls, terrac- ing, manholes, gutters and channels etc.. were executed in cut granite stones set in cement mortar. All top and black soil used for the turfed area was supplied from the existing Government nursery gardens. the gardens being re-sited elsewhere, A portable stone crusher on the site gave more than the necessary aggregate and "fines" for the cement concrete to be used. It was thus possible to obtain a very low contract price for the construc- tion of the stadium.
