Koto Tea Space is a tea House to appreciate and promote authentic Japanese tea in downtown Bangkok. It is a 50sqm interior space with 6 seats and 2 tatami floors (1.8m x 1.8m) for the exclusive tea experience. It is a renovation of the old Thai restaurant closed during COVID time.

This tea house is designed with a Japanese design concept called "Sichu no Sankyo", which means, a rural hut in the bustling city. In order to actualize this concept, there need layers to help escape from ordinary life. The space consists of 3 layers, the entrance garden, tea house, and bathroom. The deeper you go, customers can enjoy solitude and silence.

The entrance is covered with a ceramic screen and small bamboo gloves. The ceramic screen has digitally fabricated pan-Asian wave patterns covered in blue crystallized glazing supported by a metal bracket system. Each tile is oriented uniquely to block light, rain, and view to assure privacy from outside while allowing wind to pass through. 
The tea house is covered in earthy, and wooden tones to offer a cozy feeling. Overall spatial design primarily emphasizes structural elements. The wall is covered in beige texture paint, and the structural feature is painted gray. Wooden furniture and tatami spaces are nested within these structural frames while embracing horizontal lines to incorporate deep interior space. The main shelf demonstrates an asymmetrical arrangement for highlighting the main bar area while displaying tea-related products. The bar counter is coated with natural timber lacquer with brass-finished down-light to enjoy premium Japanese tea.

Bathhouse is located at the very back side of the tea house. It is a space where customers can enjoy solitude with filtered natural light and stone-finished interior space.

A new small tea space in downtown Bangkok for welcoming young tea enthusiasts for contributing to a cultural exchange between Japan and Thailand through tea.
