Duo Residences

Where the stacks are. Each stack’s outline is traced from the developer’s site plan and fitted to the land parcel on the map. Expect positions within a few metres and bearings within a few degrees. Unit types come from the colour the site plan gives each stack and add up to the published unit mix (apart from 1 Penthouse on storey 49, stack 11 (not drawn in the brochure), not in a stack here), and the map uses those same colours; 20 of the 20 stacks are also named on the developer’s floor plans, and all of those match.

Facing. A mid-block stack faces away from the side of the block it sits on. End and corner stacks (marked “corner”) have windows on more than one side; 53 of them are not yet checked against the floor plan, so the tool uses the main facade.

Heights. Towers use the developer’s storey counts at an assumed 3.4 m per storey. Buildings standing around the estate use the height in the Singapore Land Authority’s 3D model, read off OneMap 3D on 2 October 2026; where one outline covers a tower and its podium, it is cut into its parts. A building not yet in that model (still being built) uses its published storey count at 3.6 m a storey for a condo and 3.0 m for an HDB block, the averages measured for built ones. Every building is modelled as its footprint raised straight up, on level ground: no roofs, balconies, trees or slopes.

Sun. The same solar model as the Sun Path & Facing Calculator, checked to within about three minutes, with a building in the way counted as shade. The window is a point at mid-storey height on the middle of the outside wall. Balconies, overhangs and cloud cut real sun further, so read the hours as a ceiling.

Sun across the year and coolest stacks. The year grid tests the window every half hour on the 15th of each month. Coolest stacks ranks by the average of those twelve days in hours of direct sun after 2pm, least first, at the middle storey of each stack with shade from other buildings taken off; the hours for the whole day sit beside it. For a home at the end of its block the afternoon figure also counts the sun on its end wall.

Floor plans. The developer’s own pages, unaltered, matched to each stack by the layout code on the developer’s schematic diagram. A stack the plan lists as a mirror unit is the plan flipped. Floor plans: M+S Pte Ltd, DUO Residences e-brochure (whole type pages, four to six types a page). Developer's plans, not drawn to scale; areas are approximate and include balcony and A/C ledge.

Not shown. Asking prices: a resale home is priced by its owner, and what is on the market changes by the week. Anything the developer did not publish is not shown either. Details are as at 2026-10-24 and can change. Sources: Developer's brochure (M+S); OpenStreetMap.
