How to force a countably tight, initially omega_1-compact and non-compact space?

Improving a result of M. Rabus we force a normal, locally compact, 0-dimensional, Frechet-Urysohn, initially omega_1-compact and non-compact space X of size omega_2 having the following property: for every open (or closed) set A in X we have |A|<=omega_1 or |X\A|<=omega_1.
