According to Architect Recto, his firm overlaid a rectangular grid layout on a circular foot print for “maximum space utilization without compromising the efficientcy of building circulation.” Also, since the lot is in the corner and there is a flyover on the side, creating space for vehicular access was done by constructing a driveway to the rear side, the Jade Drive.
