  We present $\alpha$-attractor models for inflation based on ${\cal N}=1$
supergravity with flat K\"ahler manifolds. The function form of the associated
K\"ahler potential in these models are logarithmic square in nature and has a
visible shift symmetry in its composite canonical variables. The scalar
potential $V$ with respect to these field variables has an infinitely long dS
valley of constant depth and width at large values of inflaton field $\psi$ and
attains a Minkowski minimum at small $\psi$. We illustrate this new framework
with a couple of examples.
