Our view of The Monument Sathon

The Monument Sathon suits a buyer who wants a freehold home in the business district from two large developers, with a station at the gate and pets allowed. A one-bedroom suits a pied-a-terre or a long let to an office tenant; the three-bedrooms and penthouses suit a family who would otherwise rent a house in the Sathorn sois. It does not suit anyone who needs the home before 2030. Our off-plan buying guide explains how to judge a three-year build.

Strengths

  • BTS Saint Louis is 80 metres from the entrance and Chong Nonsi 600 metres, so you reach Silom, Siam and the office towers by train.
  • Sansiri is a listed developer with completed towers to inspect, and Nomura Real Estate holds 45% of the project, a second large developer with its own money at stake.
  • Every layout is drawn, from 39 sqm to 303 sqm, so you choose the exact plan before you commit.
  • Schools and hospitals are close at hand. Saint Louis Hospital is 400 metres away, BNH Hospital 1.1 km and Bangkok Christian College 650 metres.
  • Each penthouse has a maid's room and a Thai kitchen, rare in new Bangkok towers.

Considerations

  • Completion is scheduled for December 2029, and by 10 November 2026 construction was 2% complete. Your money is committed for about three years before you can use or let the home.
  • Get the payment schedule and service charges from us in writing, with the late-delivery terms of the sale and purchase agreement, before you reserve.
  • The site is about 1 rai for 185 homes, so open space is limited at ground level. Most facilities sit on floors 7, 25 to 27 and 29.
  • The 39 sqm one-bedrooms will appeal to investors, so expect a mix of owners and tenants in the building.
  • Sathorn Road traffic is heavy at peak hours. Drive times shown are off-peak; the BTS is the reliable route.
