In 2012, Christos Vlachos had the opportunity to participate in the development of a special legal provision, which defines the construction of bioclimatic cobblestones of buildings in Greece, The provision aimed to ensure the preservation of the precious natural landscape.

This provision foresees town planning facilities such as increasing the building factor and differentiating from morphological rules for buildings which are built beneath the surface of the soil, with the restoration of the geometry and materials of the existing natural landscape, have only one face and have no trace of construction [other than those provided in the planning framework, such as skylights].

The ability to place the building’s main spaces in a linear alignment behind the single visible face of the building results in all rooms being adequately illuminated through their openings and enjoying the view to the horizon. This alignment, in most cases, helps to reduce the required depth of the building so that the natural light from the openings reaches as the deepest point of each space.

But even in building projects that require greater depth, adequate and pleasant lighting and sunlight, is carried out through openings on the roof of the undercover, which form bright courtyards, patios, slits and through open-air corridors, providing excellent environment in the living spaces.

Shifts in light and shade, the relationship between living spaces and water, the succession of indoor and outdoor spaces with unobstructed views, are just some of the elements that make the build-in houses ideal for both private and tourist exploitation.

In most examples of built-in houses, water elements of outdoor spaces are designed as a continuation of the enclosed living spaces. This design feature, allows for unobstructed views to the horizon, while at the same time restricting viewing to and from neighbouring properties, thereby increasing the privacy of the living quarters.

The financial and functional advantages of a build-in houses are mainly related to their bioclimatic and energy characteristics as well as to its construction, thus reducing the required use of technical means to create comfortable living conditions, minimizing its operating costs.

The use of local stone, as well as materials with increased durability, makes build-in houses, constructions of minimum or no maintenance costs.
