We prove that a certain class of asymptotically locally Euclidean spaces always has a Kähler conformal compactification, and moreover provide explicit formulas for the conformal factor and the Kähler potential of said compactification. We then apply this to give a new and simple construction of the canonical Bochner–Kähler metric on certain weighted projective spaces, and also to explicitly construct a family Kähler edge-cone metrics on $$mathbb {CP}^2$$CP2, with singular set $$mathbb {CP}^1$$CP1, having cone angles $$2pi eta $$2πβ for all $$eta >0$$β>0. We conclude by discussing how these results can be used to obtain certain well-known Einstein metrics.
