You can have an expanding steady state. Just imagine an infinite plane
which is growing so that two points separated by one unit of length at time
t will be separated by two units of length at time t+1, for example:

x(t)=x(0)*2^t y(t)=y(0)*2^t

This is a simple toy universe with infinite past, future and spatial
extent.
