Penthouse — Tonson One Residence | 24th Floor | Ploenchit, Lumphini For Sale & For Rent

On a rare freehold plot in Bangkok's diplomatic quarter, Tonson One Residence holds just 80 homes across 29 floors — every one of them a corner unit, every one reached by its own private lift. The penthouse collection sits at the top of the building. This is one of them: 254.12 square metres on the 24th floor, delivered unfurnished and ready for a considered fit-out. Arrival is private. The lift opens into a foyer that belongs to the residence alone, with the service entrance and mailbox handled separately, so guests and household never cross paths. From the foyer, the plan opens eastward into a single uninterrupted entertaining volume — living and dining held in one space, wrapped in floor-to-ceiling glazing on two aspects, with a balcony opening off the far end. The dining table seats ten. Behind it, a pantry with island and twin refrigeration serves the room directly, backed by a separate enclosed Thai kitchen for heavy cooking — the arrangement that lets a household of this size entertain without the work ever becoming visible. Maid's quarters with their own bathroom sit alongside, accessed from the service side of the plan. The bedrooms occupy the western half, deliberately set apart from the entertaining wing. The master suite anchors the far end: a corner bedroom with sitting area, a long walk-in dressing corridor with fitted joinery on both sides, and a master bathroom with twin vanities and a freestanding tub. Two further bedrooms follow, each with built-in wardrobe runs, served by their own bathrooms. A powder room sits off the main circulation for guests. Throughout, the developer's specification applies: Poggenpohl kitchen and pantry joinery, Dornbracht fittings, TOTO sanitary ware, and engineered timber flooring with a 3 mm hardwood top layer. Architecture is by A49.
