Traditional Thai homes are usually built as a cluster of physically separated rooms arranged around a large central terrace. Interpreting the traditional typology of the Thai houses, the Residence Navathani consists in two parallel wings, separated by a large garden and a swimming pool. The objective of the stone architecture is to give a sense of unity and blend the building with trees, plants and other natural landscape. Trees are often allowed to grow in the central area of the traditional Thai house with plants always featured prominently to create a strong relationship with nature. The choice of Thai travertine as the main stone for the building stems from the following objectives: first, the stone must display a strong natural character with contrasting color hues and crystalline veins, which contribute to blending the architecture into the landscape. Second, the design of the stone provides a sense of unity to the building. The façade of each wing displays an array of columns of various widths and spacings and there is an alignment of the columns between the two wings. The texture is rough on the outside face of the columns and honed on the sides as it continues through the window to the inside of the house. The two wings are connected by a long screen wall that separates the drop-off area from the private areas. This wall is pierced with square openings which helps to show a relationship between the two areas. The façade facing the entrance features stone in contrasting but related ways: the right hand wing is clad with honed stone on top of a large window, while the opposite wing displays a chiseled stone wall on the bottom with a large window on top. The architecture extends to the outside of the right-hand wing with a private theater of a modern contemporary design. The stone featured on the façade changes to a minimalist grey basalt while continuing the column concept with the alternate textures grooved on the facing and honed on the sides.
