How to read the map and the colours
Every home is drawn floor by floor, coloured by unit type, in the same colours as the developer’s unit chart. Tap a stack or its number to pick it. Drag to move the map; hold Ctrl or Command and drag (or right-drag) to turn and tilt it. On a phone, one finger moves it and two fingers pinch, twist and tilt it. Zoom in to see every stack number. Navy: your stack. Orange: your storey. Dashed gold line: the view straight out of the window. Dark patches: shadows of the taller buildings at 15:00 on 19/10.

Computed for the middle storey of each tower (storey 3 in the 6-storey block), or the middle of its own storeys for a stack that does not have that storey. Sun columns are hours of direct sun on the window on 21 June and 21 December after shading by other buildings; “Afternoon sun” lists the months with an hour or more after 2pm. Open the tool for any other storey or date.

Frequently asked questions
Which Olloi stacks avoid the afternoon sun?
2 stacks get under an hour of direct sun after 2pm, every month of the year.
- #07
- #08
Mid-height storey, after shading by neighbouring blocks. The tool above shows any storey.
Which Olloi stacks take the afternoon sun most of the year?
3 stacks get an hour or more of direct sun after 2pm in at least ten months.
- #03
- #04
- #05
Mid-height storey.
Which Olloi stacks have the most open view?
4 stacks have a clear view across the whole window.
- #01 (storeys 5 to 6)
- #02 (storeys 5 to 6)
- #07 (storeys 5 to 6)
- #08 (storeys 5 to 6)
Mid-height storey. Clear means all nine sight lines (±40° of the facing) pass no building as tall as the window within 400 m.
Which Olloi stacks look straight at another block?
These face a building at least as tall as themselves, so no storey looks over it.

How this is worked out, and its limits
Stacks are traced from the developer’s site plan onto the map, and the sun and view are worked out against the buildings around them. Details are as at 2026-10-19 and can change.
Show the method and its limitsHide the method
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 developer’s unit chart and add up to the published unit mix, and the map uses those same colours; 8 of the 8 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; 16 of them are not yet checked against the floor plan, so the tool uses the main facade.
What it looks onto. The pools, lawns, courts and pavilions are read off the developer’s site plan and placed on the map with the same fit as the stacks, so they are right to within a few metres. A stack “looks onto” a pool when at least a quarter of 17 sight lines across its window (40° either side of the facing) reach the water before another tower of the project. It “faces out of the estate” when the site boundary is within 50 m straight ahead. Facility names and positions are the developer’s and can change before completion.
Heights. Towers use the developer’s storey counts at an assumed 3.3 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.
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 2026-10-19 and can change. Sources: Developer's brochure (K16 Development); OpenStreetMap.
