1The initial idea was to redefine the relationship between the output of architectural work and the need of a client, identified as the owner of the final property or the one investing in its construction. Therefore in this particular project a conventional client cannot be identified, and there are multiple owners and countless contributors instead. In crowdfunded architecture, designers take responsibilities and assume some risks to see their project built, without counting on a contracted fee for their intellectual and operative work. Architects are in control of costs across the entire chain of architectural production and manoeuvre budget constraints according to the available resources that their design can mobilize.
2The “Business Model” diagram explains the structure of crowdfunding in the Treehouse case. The three black figures represent the critical components of this business model, which are, who: the background and motivation of our team; what: the prospect of our project and related details; how: the funding goals and rewards for investors. A video in company with text and pictures conveyed the final narrative of the business model and was posted online through a professional crowdfunding platform, which served as the supervisor of the entire operation. Based on different levels of interactions between prospective investors and the project design, six funding options were defined, which ranged from 100 RMB to 10,000 RMB.
3The “Money Flow” diagram bridges money and geography while illustrating how the money was raised. Each contributor is pinned on the map to locate the origin of funders and connected to a specific amount of money which are assorted in a grey scale and arranged in chronological order. The co-builders who invested the most money and also own part of the project are highlighted as gradient columns. The rest of investors who contributed to the initial goal of 50,000 RMB are highlighted as translucent thick grey lines. The initial goal was achieved in less than three hours since the project was launched online, because most of co-builders were in Stage One. In fact, the openings for co-builders were ‘hot sells’ and run out of number before other people could get it.
4Most of investors and all of the co-builders are from the four most developed urban areas in China: Beijing, Shanghai, Guangzhou and Shenzhen. Coincidently, according to the housing price rank in 2017, these are exactly the top four areas with highest cost per square meter (Beijing 67,822 RMB/sqm, Shanghai 52,584 RMB/sqm, Shenzhen 50,900 RMB/sqm, Guangzhou 40,030 RMB/sqm; CASS, 2018). For sure young people prefer to live and work in these regions, so we assume the anxiety of living under the high housing pressure, without forgetting a concentration of interests in architecture-related initiatives and social media trends, was the main reason why most investors were from these cities. Besides, Beijing has the most pins because it is where the site is located. The project of Treehouse showed them a way of getting rid of crowded urban concrete forest, and, moreover, provided a place of their own with spiritual luxury and physical closeness to the nature. Also Lao xiang networks play a role: Lao xiang stands for the relations and bonds that people from the same village, town or province in China usually rely on for starting new businesses. As Hunan Province highlighted on the map shows more points than other regions, the cause for that are the local connection of the project initiator, Haifei Dai, whose hometown is there and whose previous work for a self-build egg house had gained reputations.
5The “Construction Cycle” diagram illustrates how and where the money was spent. A sequence of construction stages is coiling around the plan of the Treehouse from inside out. The days and actual costs of each stage are aligned together in this circular timeline.
6The matrix on the left represents detailed costs in three categories: materials, products and manpower. Except for the high costs of steel structure and wood panels, which are the main material of the cabins, we can find that quite a lot of money were spent on special needs such as floor and plumb heating systems and a freeze-proof steel plumbing system. These special needs were not part of the initial plan: as the crowdfunded money surpassed our expectations, the complexity of facilities and details were brought to a new level. More visitors and greater popularity gave us the requirement of including a shower/toilet unit and making sure it is functional during the early winter of Beijing.
7In the end, we successfully raised 177,953 RMB – more than three times our initial goal. Nevertheless, what transcends this number was a transient community based on this crowdfunded project. The Treehouse had became not only a site where people could participate the process of architecture, but also a place where people could interact with each other. It turns out crowdfunding works through not only one single piece of architecture but also the very essential meaning of place – where people talk and enjoy the space.
8This is a meaningful architectural experiment for all of us, but some issues still remain to be discussed in the future. On one hand, the ownership of the house could be crowdfunded but land property requires more careful considerations. In this case the land use right was rented by our team for 20 years and operated by the hotel manager member, in agreement with the Chinese legal framework. We believe there could be more creative ways to be explored in the future. On the other hand, the value of the architects’ labor was never counted into the construction cost cycle. As an experiment, we were happy to see everyone was enjoying this project and the result of the built cabins, but a more sustainable way needs to be developed to make it a truly new architectural practice model. If we are to consider the economies of the project seriously in the practice of architecture (Bernstein, 2014), crowdfunded architecture works in the direction of connecting ‘design value’ to what individuals put money in with reference to an architectural project (Gray, 2014). Questions remain open on who is entitled to capture and redistribute the additional value, once the crowdfunding lifecycle is over, to avoid the ‘design value’ being reduced to a product of consumerism.
