Stack View: what will I see from my new home, and when will the sun reach it?

Published 28 September 2026 · Updated 29 September 2026 · Plans as at 22 September 2026

Stack View is a tool I built that answers both questions for every home at Thomson Reserve, stack by stack and floor by floor. It shows which way the living room and balcony face, which buildings stand taller than your eye level in that direction, from which floor you look over them, and when direct sun comes into the rooms in each month.

What Stack View shows for each home

Pick a block, a stack and a floor. The page then answers, for that one home:

• Which way it faces.The compass direction of the living room and balcony, on a map of the whole site.
• What stands in front.Every building taller than your eye level in that direction, how far away it is, and from which floor you look over it.
• Floor by floor.How open the view straight ahead is on every floor of that stack, so you can see where it opens up.
• When the sun comes in.For any month and time of day: whether direct sun reaches the rooms, the balcony, or neither, and the hours of sun through the year.
• The floor plan.The developer’s plan for that unit type, turned to match mirror-image units.
• If your stack is taken.The other stacks closest to it in layout, facing and view.
• A 3D view.Look around from the balcony, with the sun and shadows for the time you pick.
• What’s around.The roads and the MRT station nearby, the pools, and landmarks buyers ask about.

Which way do the Thomson Reserve blocks face?

Every block has stacks facing two or more ways, so the block alone doesn’t tell you your view. The ways each block’s stacks face, from the developer’s plans as at 22 September 2026:

Listed from the side with the most stacks. Which way your stack faces, and what stands in front of it on your floor, is what Stack View answers.

How it works

I place every stack from the developer’s plans onto a map of the area, then give every building around it a height. The tall ones I measure on OneMap 3D; HDB blocks come from HDB’s storey counts; the rest come from OpenStreetMap or a standard height for their type. From each balcony, Stack View traces a line out every degree across the view and checks which building each line hits first, and whether that building’s roof is above your eyes on that floor.

The sun’s position comes from the US National Oceanic and Atmospheric Administration’s solar equations, worked out every 5 minutes on the 21st of each month. Direct sun counts when the sun is on your side of the block, low enough to come in under the balcony roof, and not hidden behind a building.

What it can’t tell you

Trees. They aren’t in the model. On lower floors, trees can fill much of a view that Stack View shows as open.

Exact heights. Building and floor heights are estimates, so read any one floor as give or take a floor or two.

Changes. The developer’s plans are preliminary, and anything approved or built after the model’s date isn’t in it.

Questions people ask about this

What is Stack View?

Stack View is a tool I built for new launch buyers. Pick a block, a stack and a floor, and it shows which way that home faces, which buildings stand taller than your eye level in that direction, from which floor you look over them, and when direct sun comes into the rooms in any month. It also shows the floor plan and a 3D view from the balcony.

Which way does each stack face?

At most new launches the blocks sit at different angles, so the stacks face many directions, not just two. Stack View gives each stack its facing as a compass direction, such as south-south-west, and shows it with an arrow on a map of the whole site, so you can compare stacks before you pick one.

Do higher floors always see over the neighbouring buildings?

Not always. It depends on how tall and how close the buildings in front are. At Thomson Reserve, the stacks facing Upper Thomson Road are clear of everything but the roadside trees from about the 5th floor, while other stacks face towers that no floor clears. For each building taller than your eye level, Stack View gives the range of floors from which you look over it.

Which Thomson Reserve stacks face Upper Thomson Road?

Blocks 3, 5 and 7 each have stacks facing Upper Thomson Road, to the south-west or south-south-west. In Stack View, those stacks have no building taller than eye level straight ahead from about the 5th floor, though trees aren’t modelled. Which stacks they are, and what each floor sees, is in Stack View. Message me and I’ll send you the link.

Does Stack View show when the sun comes in?

Yes. For any month and time of day, it shows whether direct sun reaches the rooms, lands only on the balcony, or is blocked by another building. It also charts the hours of direct sun on the 21st of every month, and says whether sunrise or sunset is in view from that home.

How accurate is Stack View?

It is a guide. Block positions come from the developer’s preliminary plans, and building heights are my estimates, measured on OneMap 3D where I could. Read any one floor as give or take a floor or two. Trees aren’t modelled, so lower floors may see less than the model shows, and plans can still change.

How do I get Stack View?

I share Stack View one to one rather than posting it. It’s live for Thomson Reserve. Message me on WhatsApp and say which project you’re looking at, and I’ll send you the link. It opens in any phone or computer browser, with nothing to install. If you’re comparing a few stacks, tell me which ones.

Spot a mistake? Want a project added, or something missing?

Tell me what you’d want to see from a home before you buy it. The next version is built from those messages.
