Hackney’s Collective Boat Dwellings is a proposal for a new kind of housing situated by River Lea in Hackney Wick, London. It is a self-build scheme for people living on boats who are given an opportunity to extend their homes onto the ground. By means of cooperation and self-discipline, boaters create the space which brings them together and creates a feeling of safety for those whose homes are situated on the River Lea and very often lack the sense of privacy and security. Self-builders are given a construction manual that helps them build the structure based on standard sized materials. However, given the profound nature of boaters who very often find objects to adjust their boats by themselves, the finishing of the houses is made from reused materials collected by the boaters. Hence, every house is very distinct and represents its own character. The houses play a role of extensions of boats and by means of fluent connection the two become one piece of architecture.
