This paper presents the development of a user-oriented framework to support the user reconfiguration of ubiquitous domestic environments. We present a lightweight component model that allows a range of devices to be readily interconnected and an editor to support users in doing this. The editor discovers available ubiquitous components and presents these to users as jigsaw pieces that can be dynamically recombined. The developed editor allows users to assemble lightweight sensors, devices such as displays and larger applications in order to meet their particular needs.
