Shortlisted for the PAM Awards 2023, Tangu Architecture’s Permeability Housed embraces its surroundings and sustainable principles
In an established suburb of Greater Kuala Lumpur, nestled within a close-knit community, stands a house that has undergone a metamorphosis of design innovation, research and development, and the constant trial of new ideas.
Designed by Tangu Architecture, the house is known as Permeability Housed and was shortlisted in the Alteration and Addition category at the Pertubuhan Akitek Malaysia (PAM) Awards 2023.
A unique project, the home is a progressive test bed for sustainable architecture that exemplifies the equation: lightness + permeability = sustainability.

“The house is a testament to the minimalist philosophy, prioritising ‘lightness’ across all aspects of design,” explains Tang Hsiao Seak, founder of Tangu Architecture and lead designer for Permeability Housed.
This includes a reduction in the building footprint, carbon footprint, weight, construction materials, and logistics, all achieved through thoughtful spatial configuration and the use of sustainable building practices.

The architectural design is organised around the concept of a village, where three sub-units of extended family bedroom suites are hinged around communal areas on each floor. This configuration promotes interaction and fosters a sense of community within the household.
“Spatially, the house is divided into private, communal, and ephemeral spaces. It includes a communal living and dining area, a gallery for transient use, a social kitchen, a semi-private chef’s kitchen, and private bedroom suites,” states Tang.

Circulation spaces, like the entrance courtyard, double-storey gallery, atrium, and attic, serve multiple functions, such as climate control, air exchange, visual screening, and vertical planting.
The building envelope is a marvel of design, utilising a steel frame lattice extension to wrap around the existing concrete frame, enhancing rigidity and robustness while distributing loads efficiently.

This innovative approach blurs the boundaries between the house, garden, and street, encouraging communal interaction and surveillance.
Materials selection is based on sustainability, prioritising low embedded energy, rawness, and simplicity. Traditional artisanal construction methods and vernacular materials, such as clay channels for planters, cane for fences and screens, and reused timber, infuse the house with character and history.

In the tropical climate, protection from direct sunlight and cross-ventilation are essential for cooling. As such, the building’s permeable facade incorporates natural ventilation, lighting, shading, and greenery.
“Planter boxes strategically placed near operable windows enhance airflow, diffuse natural light, and reduce solar heat gain. These features are especially vital in monsoon regions like Kuala Lumpur,” explains Tang.

The design’s emphasis on greenery as an integral part of the building envelope contributes to the ‘green plot ratio” of the plot size, reducing the urban heat island effect and creating a more comfortable living environment.
