Based on my 2 years selling experiences in Sky Condominium, the reason is simple yet complicated, because
1) Showunit in Tower E, Tower A and one in Tower D, agent lazy walk to Tower B (lol)
2) Tower ACE got more common sizes (eg. 1173sqft, 1334sqft or 1561sqft) which comprises of small, middle and big sized unit, and layout quite nice; so most ppl since see showunit 1173sqft and 1334sqft, layout and price, so will prefer to choose Tower ACE
3) Tower B is 1356sqft and 1410sqft, so it neither smallest, neither biggest; while the most expensive type of the middle sized with 3R3B or 3+1R3B, so price is higher than the middle sized 1334sqft and 1313sqft 3R2B in Tower A (since tower A, still got unit to choose from, so ppl will tend to choose unit from higher occupancy block, since Tower C&E 1334sqft sold out, so the bigger 1300sqft in Tower B 1356sqft sales slower)
4) Tower B, corridor plan slightly different from Tower A, although still same 8 units per floor, some ppl who visited Tower A first may feel they preferred Tower A corridor.
Conclusion main reason still most ppls lazy walk to Tower B and ppl tend to choose unit from more occupancy block and cheaper and smaller unit, hence i think Tower B sales only can jalan after Tower A unit running out fully.
Is this clear? hehehe

What’s the rebate for block B? Is this facing the upcoming project infront of Skyz? Been eyeing for good promo.
