Beacon
The overall size of a Beacon building is 192mm greater than the nominal internal size, e.g. a 3.66 x
2.44m building is 3.852 x 2.632m.
Base Requirements
The minimum base size required is equal to the overall building size. Assuming no suitable existing
surface, the base should be a minimum of 125mm concrete on to well consolidated hardcore.
The concrete should be of minimum C20/25 grade in accordance with BS8500 Concrete: The
Complementary British Standard to BS EN 206-1.
The base should be flat, level and square, and preferably be raised slightly above the surrounding
ground level.
