Sun & facing study · Fully SoldJervois Mansion
Which of the 130 homes at Jervois Mansion get the morning sun, which face the afternoon heat, and how the neighbours shade each stack — in 3D, from the developer's own site plan.
Every stack, and the way it faces
The towers from the developer's own site plan, standing among their real neighbours. Each stack is coloured by the direction its units face.
The sun over the site, minute by minute
Real shadows from the towers and every building around them. Play the day, or pick any date and time on the bar.
Morning sun, afternoon sun
How many hours of direct sun each facing gets — before and after noon, today and across the year.
Pick a stack and a floor
Hours of direct sun on that stack's windows, with the neighbours in the way — worked out from the real buildings around.
What else is around
Schools within 1 and 2 km, HDB resale prices next door, BTO projects and other launches.
Your next step
The project page, the full 3D launch map, a buyer playbook — and someone to ask.

Facings are worked out from the developer's site plan and north arrow and rounded to the nearest of 8 points, so a unit's exact view may differ. Sun hours here assume an open sky; the 3D chapters above add the real neighbours. Morning = before solar noon (about 1 pm in Singapore).
Sun positions are calculated, not measured. Building heights come from OpenStreetMap and HDB where recorded and are estimated elsewhere; trees, balconies, awnings and the shape of the ground are not modelled, so real sun hours can be lower. New launch towers are drawn from developer site plans and facings are rounded to 8 points. A guide for comparing homes, not a survey. The classic sun compass
