Theme B: Creating a livable, healthy and environmentally viable citiestherefore has been approached with agendas covering economic, environmentaland community aspects.3.1 Economic SustainabilityTo maintain competitiveness of the development throughout its life, the designelements introduced to bring retail success and major increase in value are –3.1.1 Character of a Regional Type Shopping CentreThe sloping nature of the site and its proximity to the existing MTR structuresresults in a relatively high development cost. To improve the revenue generationand achieve economies of scale, the size of the development has been increasedfrom 27,750m 2 to an optimum size of 44,830m 2 thereby generating additionalgross annual revenue in the scale of US$5.7M and integrating with of the existingLei Yue Mun Plaza as a regional type shopping centre with a total size of 60,000m 2 .3.1.2 Flexibility for ChangeThe layout design should have the capacity and flexibility to cater for changes tocope with ever-changing retail trends. A regular structural grid of 8 metres by 12metres is applied to optimize flexibility and efficiency in retail planning; locatedthe atrium close to the centre of the development to create shops of optimumdepths on all frontages; and, aligned route of arcade primarily along the centralatrium and connecting bridges thereby maximizing exposure and commercialattractiveness for all commercial tenants.3.1.3 Utilization of Completed PilesFoundation works had been completed based on a previously approved layoutdesign. Increase in size of the development of over 60% requires installation ofadditional foundation. By rationalizing the structural grid to align with the existingfoundation as far as practicable and optimizing the use of the spare capacities ofexisting piles, only less than 20 percent of the building loads is required to besupported by the additional foundation.202
