Located on the quiet Na Jomtien beach, between the fishermen’s village and the city of Pattaya, Mason’s architecture rests on a 12m-high granite hill inclining down to the sea, where Ang Sila (local stonemasonry community) is nearby. The resort consists of 35-unique-pool-villas and its facilities, including restaurant, spa, fitness, pool and beachside bar. C-shaped concrete form is metaphorically sculpted into ‘cave’, using the integration of natural stone and other materials. The combination of material mastery and detail is also carved into concrete, terrazzo, wood, glass, in collaboration with the local artisans. In descending the slope, the cave-like villas are carved on one third of the 4,600 square-meter site, maximising the sea view while keeping tranquility and privacy within. The design accent also can be seen in decorative crafts such as sculptural vases and washbasins made from granite rocks by Ang Sila local sculptors. The collaboration between the project owner, the architect and the local artists makes MASON not only a retreat resort but the architecture that helps its community and is locally unique in the place of nowhere else.
