Inner cities are becoming over saturated with high-end offices and hotels made from concrete substructures and lavish material finishes. People are being pushed out and the ecosystem of live-work and play within the inner city context is becoming extinct. Instead cities are becoming more and more commuter orientated. Infill City is a concept which is based on modular construction techniques using timber, open-sourced products provided by Metsa Wood. By utilising modular timber construction we can infill vacant spaces within the city and create collaborative living environments for inner city dwellers. The core construction would be based on a platform construction whereby elements would be pre-made off site on a 5 X 5 meter grid system which would allow for micro apartments with shared amenities with external terraced spaces between each level. XL Kerto LVL Q wall elements would be utilised, with RIPA Floor elements for high load bearing capacities meaning multi storey infills could be achieved in dense inner city environments. The external walls would be clad in site specific materials such as glazed brick tiles to match the appearances of adjacent buildings.
