The 2 Bedroom Premium (2H1) and 2 Bedroom Premium + Study (2S2) each have a master bath and a Bath 2, 91 units in all, while the 67 units across the 2 Bedroom Deluxe layouts (2C1, 2C2, 2C3) and the 2 Bedroom Deluxe + Study (2S1) have one bathroom. 2H1 also has a household shelter and 2S2 a study, and both measure 71 sqm (764 sqft) against 60 to 65 sqm for the Deluxe types. Q: What are the unit types ending in -P? A: They are the level-3 versions of 11 layouts, 19 units in all: A1-P, A2-P, 1B1-P, 1H1-P, 1S1-P, 2C1-P, 2C3-P, 2S1-P, 2S2-P, 3H1-P and 3D1-P. Each has a PES where its base layout has a balcony. Ten keep the base layout’s area exactly; 3D1-P has a 14 sqm PES against the 12 sqm balcony of 3D1, making it 116 sqm against 114 sqm. Q: Which unit types have an indoor lounge or family area in place of a balcony? A: Three layouts, 7 units: 1B2 (#04-21, #07-21 and #05-30) and 2C2 (#04-22 and #08-22) have a lounge, and 3D2 (#05-23 and #07-23) has a family area. Each is 2 sqm larger than the balcony layout of its stack: 47 sqm against 45 for 1B1, 62 against 60 for 2C1, and 116 against 114 for 3D1. Q: What do the 3 Bedroom Luxury kitchens have that other kitchens do not? A: An enclosing bi-fold glass door and a kitchen island.
