Abstract: The $alph{a}^{\prime }$-deformed frame-like Double Field Theory (DFT) is a T-duality and gauge invariant extension of DFT in which generalized Green-Schwarz transformations provide a gauge principle that fixes the higher-derivative corrections. It includes all the first order $alph{a}^{\prime }$-corrections of the bosonic and heterotic string low energy effective actions and of the Hohm-Siegel-Zwiebach $alph{a}^{\prime }$-geometry. Here we gauge this theory and parameterize it in terms of a frame, a two-form, a dilaton, gauge vectors and scalar fields. This leads to a unified framework that extends the previous construction by including all duality constrained interactions in generic (gauged/super)gravity effective field theories in arbitrary number of dimensions, to first order in $alph{a}^{\prime }$.
