MAVISTA Phrom Phong

Construction status is now clear enough to treat the scheme as an active build rather than an early concept. On 29 June 2026 Major Development announced the formal commencement of construction at the Sukhumvit 39 site, and its current public completion target is 2029. That supersedes older third-party project cards that still show 2027. The developer’s project page retains a legal disclosure dated 5 July 2024 that had already contemplated an August 2029 completion but, at that time, recorded that EIA approval and a construction permit had not yet been obtained. By November 2025, Thai property and business press reported that the EIA had been approved, and Major Development now maintains a dedicated EIA portal entry for the project. For a buyer in 2026, the sensible baseline is therefore under construction with a 2029 completion target, while the precise contractual handover month remains something to verify in the sale agreement.

The legal project owner named by the developer is 39 Residence Company Limited, with Major Development presented as the developer and consumer-facing brand. The official disclosure also says the building is intended to be registered as a condominium after completion. That distinction matters for foreign buyers. Thai condominium law allows foreign freehold ownership only within the statutory 49% foreign quota measured against the total condominium-unit area. Several current market sources describe MAVISTA as freehold, but none of the public material we found provides a live foreign-quota availability table by residence. A foreign buyer should therefore treat “freehold project” and “this particular unit is available in foreign freehold” as two different statements. The latter needs a unit-specific confirmation. We also found no public, specific to the project leasehold programme that could safely be presented as the standard fallback outside the foreign quota.

The unit mix is broad even though the bedroom count is narrow. Major Development confirms an overall range of three to five bedrooms and 204–517 sqm. Specialist project sources then break that into families such as Decorum, Continental, Embassy and Presidential. Three-bedroom homes span roughly 204–348 sqm; four-bedroom formats sit around 321–447 sqm; five-bedroom Presidential residences are generally shown around 481–517 sqm. Published reference plans include Decorum North at 204 sqm with three bedrooms and four bathrooms, Continental 1 at 321 sqm with four bedrooms and five bathrooms, and Presidential 2 at 481 sqm with five bedrooms and six bathrooms. Those are not minor variations. A 204 sqm three-bedroom and a 348 sqm three-bedroom serve different households, furniture plans and service needs, so a buyer should compare the actual floor plan rather than assuming that bedroom count is a reliable proxy for value.

Amenity design follows the low-density positioning. Major Development highlights a 27-metre swimming pool, the Symposium meeting room and concierge service. Cross-checked project sources add a panoramic gym, yoga studio, golf simulator, business and private lounges, social and recreation spaces, garden areas, children’s facilities, sauna and steam facilities. Parking is another standout specification: the developer advertises a 357% parking ratio relative to the number of residences, and market project databases describe an automated system with EV charging. That is more relevant here than it would be in a small-unit transit-oriented condo because households buying 200–500 sqm homes may have multiple cars, drivers and frequent guests. Still, a headline parking ratio is not the same as a contractual allocation. The exact number of spaces attached to a residence, size restrictions, driver access and guest arrangements should be confirmed in the unit documents.

Pricing is fragmented rather than presented through a single public developer price list. In the current FazWaz project inventory checked on 29 August 2026, five homes are advertised across a wide band starting in the mid-THB 60M range and extending to roughly THB 190M. Individual examples include a 204 sqm three-bedroom at about THB 64.6M, a 321 sqm four-bedroom at about THB 119.6M and a 481 sqm five-bedroom at about THB 190.8M. A DDproperty feed surfaced through Think of Living in August 2026 shows additional asks around THB 67M, THB 124M, THB 198M and THB 209M, reinforcing the point that price is highly residence-specific. These are asking prices, not evidence of completed transactions or guaranteed availability. The lower figure in this dossier is only a market-entry anchor. A fair comparison needs same-day availability, floor, orientation, fitted specification, ownership quota and payment terms.

Commercial terms are the main unresolved public-data issue. Prima Realty publishes a THB 1M booking fee with 30% down and 70% on completion, while Keller Henson publishes THB 500,000 with 15% down and 85% at completion. Because we did not find a current official public payment schedule from Major Development, neither version is safe to hard-code as the project’s present terms. The same discipline applies to the exact handover month and the live foreign quota. At this budget level, a buyer should insist that the availability sheet, unit plan, specification, parking allocation, foreign-quota confirmation, payment schedule, title due diligence and sale contract all refer to the same residence and the same point in time. The project has enough verified substance to evaluate seriously; the remaining gaps are transaction-specific rather than questions about whether the development itself exists.
