Perforated brick walls enclose the concrete structure of an old house in central Vietnam, which has been remodelled by architecture studio Tropical Space (+ slideshow).Vietnamese architects Tropical Space refurbished an old two-storey house occupied by a family of three in Da Nang, a coastal city in Vietnam.Retaining only the concrete slab structure, the architects enclosed the space with a perforated grille of brickwork to create a new residence named The Termitary House.According to the architects, the orange-red bricks reference the baked-brick towers built on sacred sites in the region during the Champa Kingdom between the 4th and 15th centuries, while the plan – with a living space protected in its centre – was inspired by the earthen chambers of termite nests."The special design of the baked-brick walls with a lot of holes, together with the large inter-floor space, allows breeze and light to get to all the corners of the house, even the hardest-to-access areas," explained the architects.This arrangement is designed to deal with the fluctuating climate of the area, which varies between two extremes – a dry hot season and a rainy season with several tropical storms each year.
