Motivated by the main results of the articles by Hattori and Bouziad, we seek to answer the following questions about Hattori spaces. Let A be a subset of the real line, then: Given a compact set in the Euclidean topology, under what conditions is compact in the Hattori space ? When is a quasi-metrizable space? When is a semi-stratifiable space? When is a normal space? When is a Lindelöf space? We obtain complete answers for 3 out of these 5 questions, while the last ones remain with partial answers, among them: \ Theorem: If is analytic, then is not normal. Moreover when we work on the Solovay Model we can improve the previous result to only require to be uncountable.
