Perimeter block has been one common and important typology in urban design and planning studies and implementation. Having been developed through various research and studies, perimeter block can still be optimized as an urban typology.

Research and studies in passive solar urban design has various focus including solar radiation, daylgihting, thermal comfort and wind. The thesis will focus on solar radiation performance of perimeter block and fnd the optimized criterias and approaches to be implemented in gaining more density. Perimeter block still can gain higher density without sacrifcing the functional and design aspect as well as its performance. The thesis study on the confguration of the building in term of which part can be built higher without blocking other part’s solar access.

Design criteria and aspect are implemented in an urban design of Old Oak site in London with the objective to gain high density, compact and transit oriented urban design.
