Stuck in experimentation: exploring practical experiences and challenges of using floating housing to climate-proof waterfront urban development in Sweden

Abstract

With climate change already underway, cities are looking for ways to deal with its effects. To balance urban waterfront development and climate adaptation, floating housing is presented as a promising solution—however it has not been studied sufficiently. This paper explores floating housing as urban climate experimentation, targeting vision/motivation, practice and upscaling in a national context where support mechanisms and traditions are absent. Interviews with innovation entrepreneurs and municipal planners involved with planning and building floating districts show that, with one exception, the Swedish initiatives are at odds with the theoretical assumptions behind urban climate experimentation. Initiatives are neither challenge-led in terms of climate risk nor inclusive and community-based. Rather, the small-scale private entrepreneurs are pioneers in offering unique living on water as one-off innovations. While allowing experimentation, municipal planners are less convinced by the effectiveness and appropriateness of upscaling. Floating housing may contribute to local identity building and place marketing, but are riddled with implementation challenges regarding shoreline protection, privatization/accessibility, limited market interest and urban development fit. While the floating houses themselves withstand flooding, thus safeguarding individual house owners, they do not protect the land-based city with its vulnerable waterfront development patterns. Results thus suggest the limitation of floating houses in shifting development pathways and strengthening urban climate proofing.

A Value-Based Multi-Criteria Decision-Making Approach Towards Floating House Development: A Case Study in Hong Kong

“…Recent research has further explored the potentials of floating houses in relieving housing shortage or global climate crisis. These studies have discussed the opportunities and challenges of floating houses based on practical experience (Lin et al, 2019;Moon, 2015;Penning-Rowsell, 2020;Storbjörk & Hjerpe, 2022) and reviewed associated construction technologies such as the building stability and mooring system (El-Shihy & Ezquiaga, 2019;Endangsih & Ikaputra, 2020). In addition, floating houses have also been investigated in its sustainability and energy efficiency (Moon, 2014;Habibi, 2015), along with its capability of adapting to floods (Kusliansjah & Suriansyah, 2013;Strangfeld & Stopp, 2014).…”

Urban planning, management and housing policies in European river cities and city of Belgrade: Case study

“…Једноставно, " (...) са климатским променама које су у току, градови траже начине да се изборе са њиховим последицама. Да би дошло до уравнотежења урбане обале и климатске адаптације, стамбени простори на рекама у метрополитенским градовима показали су се као обећавајуће, али још увек недовољно проучавано решење" (Storbjörk and Hjerpe 2022). Све чешће су урбанистичке "визије" изградње градова на води, као јединственим комунама које треба да допринесу адаптабилности за будућност.…”

Climate Adaptation Measures for Enhancing Urban Resilience

“…Development of floating or stilt-based structures: These structures can offer a viable solution for communities that face increased flooding or sea-level rise. Floating homes are already in use in parts of the Netherlands [117]. 10.…”
