"Recessed Roof" Residence in Bangkok Formed Around an Interior Courtyard

Designed by Anonym Studio in Bangkok, Bhoon+ House is a modern architectural project built on a 376-square-meter plot by utilizing the former lawn area of an existing family residence. While the new home is shaped around an open interior courtyard positioned right at the center of the structure—visually connecting the two houses—it maximizes natural light through its recessed roof form and linear layout.

Architectural Features and Layout of the Design

Bhoon+ House is conceived as a long, linear volume that follows the shape of the right-angled rectangular plot. Positioned against the street facade on the eastern side, the building is designed to adapt to the sun's movement throughout the day. This layout protects the main walls from direct sunlight, while large glass surfaces on the north-facing facade allow the interior space to integrate with the garden.

The approximately 400-square-meter interior is organized around a seamless communal living space that includes a living room, dining area, and kitchen. One of the project's most distinct features is the recessed roof cutout designed to accommodate the growth of a central tree while maintaining the continuity of the main roof plane. This architectural detail ensures that the landscaped interior courtyard becomes an integral part of the building's overall form. Additionally, operable windows in the kitchen section promote cross-ventilation, while service areas and a traditional Thai kitchen are positioned separately at the rear of the structure.

Material Selection and Ventilation Solutions

The exterior character of the project stands out with its balanced use of different materials. While the facades facing the courtyard are equipped with expansive glass surfaces that enhance transparency and the connection with the outdoors, the rear service volume is expressed by a curved wall built from white-painted brick. Voids within this brick wall allow air and light to circulate, creating a natural ventilation shield for the enclosed service area.

Sectoral Reflections of Courtyard Use in Architectural Projects

Balancing privacy and communal living spaces in dense urban fabrics and contiguous family properties is a crucial design criterion in modern architecture. As seen in the Bhoon+ House project, preserving existing landscaping and integrating it into the center of a new volume, alongside shaping roof forms according to environmental elements (such as existing trees and solar angles), offers a functional model for sustainable and climate-responsive residential design.
