The CT house was born from the project to renovate a detached single-family home made up of five existing detached buildings on a plot resulting from a subdivision of the land, with one initial plot being expanded by taking part of the neighbouring plot: the main house on the original plot, with attached auxiliary building and porches; an auxiliary building with services for the pool, also on the original plot; a garage and workshop, both on the original plot; and the existing main house on the annexed plot, with an attached porch.

The renovation project consisted in partially demolishing some buildings and rehabilitating others to create a single-family home that would fit the specific needs of the family that would live there.

On the one hand, as one of the residents has reduced mobility, the project proposes adapting the existing buildings, all ground floor, to make sure all architectural barriers are removed and ensure accessibility to the whole plot.
