Whoever wanders around Saigon, a chaotic city with the highest density of population in the world, can easily find flower-pots crampped and displayed here and there all around the streets. This interesting custom has formed the amused character of Saigon over a long period of time and Saigonese love their life with a large variety of tropical plants and flowers in their balconies, courtyards and streets.

The house, designed for a thirty-years-old couple and their mother, is a typical tube house constructed on the plot 4m wide and 20m deep. The front and back façades are entirely composed of layers of concrete planters cantilevered from two side walls.

The distance between the planters and the height of the planters are adjusted according to the height of the plants, which varies from 25 cm to 40 cm. To water plants and for easy maintenance, we use the automatic irrigation pipes inside the planters. We named this tropical, unique and green house “Stacking Green” because its façades filled with vigorous and vital greenery.

The house structure is a RC frame structure widely used in Vietnam. The partition walls are very few in order to keep interior fluency and view of green façades from every point of the house. During the day we get the varying light with the time of day trimmed by the top-light in the center. In the morning and the afternoon, the sunlight enters through the amount of leafs on both façades, creating beautiful shadow effects on the granite walls, which are composed of strictly stacked 2cm stones.

The green façade and roof top garden protect its inhabitants from the direct sunlight, street noise and pollution. Furthermore, natural ventilation through the façades and 2 top-lights allow this house to save a big energy in a harsh climate in Saigon. Concerning these ecological approaches, we referred a lot to the bioclimatic principles of traditional Vietnamese courtyard house.

In this chaotic city, we defined the full variety of surrounding greenery as a context of Saigon and applied to the main concept of this house. Although the Saigon townscape is getting uniformed and boring under the influence of the furious urban sprawl of recent years, we intended this house to inspire people to re-define and re-increase the greenery as the character of this city. “Stacking Green” is just one small house, but it is generated from the context of Saigon. We hope that “Stacking Green” makes Saigon become more distinguished and fascinating with much more tropical greenery in the future.

    The question is if you could make this off-grid and zero waste, then it would be perfect!

      why not? unplug from electrical, go to bed by sunset, grow herbs and food on your facade garden etc etc.. all up to you

    Wonderful concept, but like the Beauborg it will become, in less than ten years, very grubby.

      How do YOU know this?

      You are insulting the owner/s’ ability if not motivation to maintain their home. Such presumption or are you basing it on your dis/ability or lack of motivation to keep it well maintained? Likely.

      There are such things as antifungal paint, cleaning solutions and manpower abounds.

    Love the design concept. Details are great as well that is really hard to achieve in Vietnam due to the poor construction quality.

    Just worried a bit about the house’s security as it seems easy to access the house through the voids between the ‘green stacks’ given to the low security level of the local living environment. And the staircase is nice but its design may be a safety issue for the old mother or when the couple have their children.

    Its projects like these that inspires me to be inventive – to use the culture and resources around you to produce beautiful architecture. Very Japanese-like might I say!

    I also loved the open fluid space with greenery but wondered about rain and monsoons. I also fear for the safety of the house. Idyllic though.

    công trình tưởng bình thường mà lại phi thường , làm việc bình thường theo cách phi thường

    Love the atmosphere and especially the combinations of very tactile materials. Am I reading this wrong or is there no actual view through the bushes to the outside though, except for the car? I know there is propably a lot of light coming in but I was wondering…
