The view in front of you · Bangkok's hidden risk

Why this matters

Your unit's view is a real component of its value. Sukhumvit corridor data shows a 15 to 25% premium for unobstructed-view units vs same-building blocked-view units. That premium is what evaporates if a new tower goes up across the soi · or worse, on the adjacent plot.

Bangkok zoning is permissive. A neighbouring plot zoned for 35 storeys can stay empty for a decade and then suddenly trigger development when the macro is right or when a new owner buys it. Foreign buyers often don't check what's allowed next door · they buy on the visible view, not the buildable view.

The four signals to check before you buy

• · **Adjacent-plot zoning** · what's the maximum buildable height on every plot within 100m? Bangkok City Planning Department publishes the zoning map. We pull it for every project we underwrite.
• · **Adjacent-plot ownership + activity** · is the lot owned by a known developer? Has a building permit been filed in the last 24 months? Has the lot been bought / sold recently (a transaction often precedes a development decision by 12-24 months)?
• · **EIA filings** · the Environmental Impact Assessment for a tower is filed with the Thai Office of Natural Resources and Environmental Policy and Planning · search the registry for any approved or pending EIA within 200m of your unit.
• · **Setback from your unit** · even if a tower goes up next door, Bangkok building code requires setbacks. A 35-storey tower 30m from your window obstructs less than one 10m away. Our underwriting includes the geometry.

What 'protected view' actually means

There are three levels of view protection in Bangkok:

• · **Genuinely protected** · the view faces a permanent feature · a park, a river, a temple complex, a historical district. The view cannot be built on. Examples: Lumpini-facing units (98 Wireless, Saladaeng One), riverside units (Mandarin Oriental Residences, Park Hyatt), park-adjacent stock (Magnolias ICONSIAM facing Charoen Krung).
• · **Probabilistically protected** · the view faces a low-density area, mature buildings unlikely to be redeveloped, or low-zoned plots. Sukhumvit Soi 39 to 49 stretches mostly fall here · existing low-rise won't be displaced economically for at least a decade.
• · **Unprotected** · the view faces an empty plot or low-rise that could be replaced. This is the highest-risk profile, and the price premium for the current view is fragile. Common in Phra Khanong / On Nut / Sukhumvit 71+ corridors where land assembly is still active.

How we factor this into Khorna underwriting

Every project we shortlist has a view-risk assessment in the underwriting deck · classified as protected / probabilistically-protected / unprotected, with the specific concerns flagged (e.g., 'Plot Y at 45m has 30-storey zoning · monitor'). We don't always recommend against unprotected views · sometimes the price reflects the risk and the trade-off works. But we surface it before you sign, not after.

What to ask the developer

• · What's the buildable height on each plot within 200m of this unit?
• · Are any of those plots owned by entities with active EIA filings?
• · What does the buyer-protection clause say if a neighbouring tower obstructs the unit's view (some luxury developments include partial protection · most don't)?
• · Has the developer themselves applied for any adjacent-plot permits (sometimes the same developer is the one who'll build next door)?

Your view is only as protected as the zoning, the adjacent plots, and the time-to-development on the empty lots around you. Buy with this clear-eyed, not on the visible vista.
