This final report presents the results of a demonstration project into the use into the use of modular units in the renovation and extension of existing buildings. The report reviews the current uses of modular construction, both in new buildings and renovation, and shows how modular units may be attached to the side and the roof of buildings to provide new facilities and improve the appearance of these buildings. Two demonstration buildings were completely renovated.

Different types of new modular units were used in the demonstration buildings, such as balconies, staircases, lift shafts, modular panels and room-sized modules. Both buildings were monitored during construction and tests were performed to demonstrate their performance in service. Additional test were carried out to assess the robustness or stability of the stacked modules to removal of part of their support, which is an important requirement for tall buildings.

Design guides for different types of modular construction were produced in order to help designers in their future work in the field of building renovation. Both social and economic assessments were made to verify when renovation using these techniques is viable.

Decision-making tools were also prepared to assist clients in the choice of modular construction. As a result of the project, considerable interest in modular construction has been achieved. New projects have been accomplished in Finland and the UK. By means of these products and systems, building owners and designers have better tools and information to assess new ideas and possibilities to realise future renovation projects.
