In this work, we take a topological approach and introduce a homotopy model of the orbit space of a maximal torus action on Gr(2, ℂ5). Using this homotopy model, we compute the integral homology groups and study the homotopy type of the orbit space. More precisely, we endow the homotopy model with a CW complex that contains one top cell and determine the homotopy class of the attaching map of the top cell of the orbit space.
