In the frame of tectonic theories, this project aims to achieve a communion between shape, structure, function and context in the architectural realm. The thesis is based in an existing competition which calls for a renovation and expansion of an abandoned Bath House in Liepaja, Latvia. Considerations towards the role of the Bath House in a city context will establish the guidelines for an Architectural intervention in which, a dominating parameter is to respect and enhance the essence of the original building. Special attention to the details in terms of the Tectonic theories of Frascari will be taken, prioritizing an overall coherence in the narrative derived from the encounter of the old building and the new expansion.
