Hotel Indigo Bangkok Wireless Road, a younger brand from the Inter-Continental Hotel (IHG) chain, is located on the leafy tree-lined Wireless Road in Bangkok.

Wireless Road has a strong historical background as an area for embassies and embassy residences. It was also the location of the 1^st broadcast and telegraph station in Thailand, dating back to the King Rama VI period, giving the street its name. The façade design of the hotel derives from the Morse code signal to celebrate this aspect of its history.

The hotel is also situated on a busy pedestrian route next to a large mixed-use office complex. The concept formulated early in the project was to connect with the neighborhood as much as possible. Not only are the lobby and restaurant on the lower levels well connected to the street; the guest rooms also feature bay windows, both with and without balconies, that allow guests to enjoy the view of the embassy area and the greenery opposite the hotel.

To avoid standard city hotel configurations, such as closed corridors and 4-metre wide guest rooms, typical guest rooms at Hotel Indigo Bangkok Wireless Road are therefore designed on 6 m x 6 m modules. These feature a wide frontage, with the typical floor configuration allowing for 5 corner units out of 11 units on each floor.

All guest rooms feature full-height bay windows that offer a spot for guests to contemplate or connect with the magnificent views outside. These bay windows are subsequently a strong integral element of the façade design. The hotel façade reflects the room configuration inside, resulting in a strong character of inside-out architecture.

The idea of having a naturally ventilated corridor was conceived early in the design concept stage. Unlike typical city hotel corridors that offer no connection to outside, the corridors on each floor are within an atrium space, allowing guests to visually connect with the outdoors. The design of these atriums also allows cross breezes into the corridors, eliminating the need for air-conditioning. The atriums animate the building façade, gave a porous quality to the building mass.

The colour palette for the façade utilizes shades of anodized bronze, gold and bronze tinted glass. On the ground floor, elements of timber, bronze and natural stone on the lobby façade add to the project character.
