The Monument Thong Lo — Review, Sale & Rent Prices

The Monument Thong Lo is Sansiri’s statement super-luxury tower — just 127 residences across 45 floors, every unit served by a private lift, with starting sizes far larger than typical condos anywhere on the soi.

Location

At the Sukhumvit end of Thonglor, genuinely walkable to BTS Thong Lo in under 10 minutes, with the restaurant zone of Thonglor 1–10 within strolling distance — a rare combination of rail convenience and mid-soi lifestyle.

Highlights

• Maximum privacy — few units, private lifts, quiet floors
• Large residences only — 2–4 bedrooms, high ceilings, open city views
• Sansiri flagship quality — materials, common areas and concierge service

Considerations

Both purchase and rental prices sit at the very top of the Bangkok market; resale liquidity follows the luxury cycle. Buyers are mostly wealthy end-users and international purchasers.

Prices (approximate)

Sales around THB 350,000–450,000 per sqm; rentals from roughly THB 90,000/month. (Approximate as of July 2026 — verify current prices.)
