Example 2 A young bachelor has decided that his R-1 zoned property, with a Total Lot Area (TLA) of 450 sqm and located in Anti polo City, shall host his dream house. The Project Site is an inside lot, with a IS-meter wide frontage facing west. The Project Site uniformly slopes at I 0% towards the 14-meter wide street, i.e. the road-right of way (RROW) that is relatively flat and which has 2.0-m wide sidewalks (which includes a 0.80-m wide planting strip) at both sides. The surface at the center of the Project Site frontage is considered as elevation 0.0-m. A roofdeck shall be provided which will serve as a viewing and entertainment area for guests because of the magnificent view of the Manila skyline and the sunset.
