The Tubkaak Krabi Boutique Resort is located on a site facing a majestic beach with panoramic views to distant islands. The rear of the site is adjacent to a large national park, and the mountainside adjacent the resort is the source of a natural creek that flows through it. As a result of Nature provision, the entire site is lavishly covered with plants and trees. Its beach is further blessed as the result of the natural stream that flows into it from the valley. There are 2 phases to the project, both of which were designed by A49.

The new part of the resort, adjacent to the original 2 acre resort complex, further expands the complex by approximately 1.3 acres. Additional clusters of pool villas and communal facilities, such as a meeting room, restaurant, fitness room and spa are provided within it. Again, the villas picturesquely blend the indoors and outdoors. The internal space was deliberately built to be in harmony with the existing topography and environment, whilst guest privacy is maintained within landscaped walls and internal garden space where guests can even enjoy undisturbed showers outdoors. Unlike the first phase, the client wanted a honeymoon destination that gave extra privacy. As with the first phase, the design focuses on making the buildings as integrated to their natural surrounding as much as possible, including the retention of ancient trees. It includes pool villa accommodation, as well as a common swimming pool that has been extended from the first phase. This gently flows through to this second phase from the natural reservoir that acts as the source and retains water from the mountain behind the resort.

Every single building was tailor-made to blend into its specific location, with common curved edge gables and the ridgepoles being used to create a unique character of roofs for the Tubkaak Krabi Boutique Resort. Their form is inspired by the unique form of traditional Ko Lae and Naga boats (the Naga is a great serpent mentioned in Buddhist mythology). Detail elements for bed screens, door locks, etc., were designed in a tropical vernacular style in keeping with the project DNA.

The spa consists of three slender truncated conical structures, all of which are timber clad on their exteriors and interiors. Inside each, the tapering, high-ceiling space terminates in an oculus that fills the interior with a soft light. These structures tower above other buildings on site and create a striking silhouette amongst the distinctive roof forms that define the rest of the property.
