NovSiam Inter World Asset
Siam Inter World Asset Co., Ltd. is an active Thai company, registration number 0105557047874, incorporated on 1 April 2014. Its residential development record is publicly centred on Wyndham Jomtien Pattaya in Na Jomtien: the official project site identifies Siam Inter World Asset as the developer, while a January 2024 company announcement described the scheme as the company's first project. That distinction matters because the company also markets a much longer hospitality and tourism background, which should not be confused with a long history of completed residential developments.

Overview
Siam Inter World Asset Co., Ltd. is an active Thai company, registration number 0105557047874, incorporated on 1 April 2014. Its residential development record is publicly centred on Wyndham Jomtien Pattaya in Na Jomtien: the official project site identifies Siam Inter World Asset as the developer, while a January 2024 company announcement described the scheme as the company's first project. That distinction matters because the company also markets a much longer hospitality and tourism background, which should not be confused with a long history of completed residential developments.
Track record
Wyndham Jomtien Pattaya gives the company one substantial residential development that can now be assessed as a finished physical asset. Official project information lists four seven-storey residential buildings, 630 condominium units and 55 commercial units, with construction starting in Q2 2020 and the original completion target set for late 2023. In January 2024 the company announced that construction had been completed and units were ready for transfer. Thailand's Smart EIA Plus database also records four approved environmental reports under the same legal entity for the Thai Bua Tower hotel project, which supports an earlier hospitality-property history but does not establish a multi-project condominium delivery record.
Segments and prices
The verified product is a resort-style condominium: studios of about 24.45–34.90 sq m, one-bedroom units around 49.40–50.00 sq m and two-bedroom units around 76.45 sq m. The company quoted a starting price of THB 3.39 million in January 2024. Pearl Property's current August 2026 project page shows available offers at roughly THB 4.0–9.3 million; that is a live market reference for the inventory shown by the agency, not a universal developer price list. Because the project is completed, buyers should distinguish remaining developer stock from resale units, as fit-out, contractual benefits, hotel-program eligibility and transaction costs may differ.
Geography
Siam Inter World Asset's verified residential development activity is concentrated in Na Jomtien, Sattahip district, Chon Buri. The company's registered address and Wyndham Jomtien Pattaya are at the same location. The sources reviewed for this profile do not establish a second residential project in Bangkok, Phuket or another Thai market, so the developer's confirmed residential footprint is local rather than nationwide.
Reliability and public record
Buyers have several concrete verification points: an active legal entity with a government registration trail, a completed development, a live Wyndham Jomtien Pattaya property on Wyndham Hotels & Resorts' own global website, and a public project history through completion and transfer. The limitation is the depth of the residential track record: the company itself described Wyndham Jomtien Pattaya as its first project. Wyndham branding confirms a genuine hotel operation, but it is not the same as a guarantee of Siam Inter World Asset's obligations to a condominium owner. The same caution applies to advertised investment returns, which depend on the actual contract, responsible legal entity and payment conditions rather than the hotel brand alone.
What to verify
For a specific unit, first establish whether the seller is the developer or a resale owner. Then verify the condominium title, foreign-quota availability, any outstanding juristic-person charges, transfer costs and the actual furniture and equipment included. The hotel investment programme needs a separate contract review: the official project website advertises a 6% annual return for eight years and expressly says that the programme applies to Building 2. Confirm whether the chosen unit is covered, whether the benefit survives resale, which legal entity is responsible for payment, the calculation base, deductions, end date and the exact terms of the 15 owner-use days. Buyers should also review the term of the hotel-management arrangement and what happens if the operator changes.

Frequently asked questions
Are Siam Inter World Asset and Wyndham the same company?
No. Official project materials identify Siam Inter World Asset Co., Ltd. as the developer of Wyndham Jomtien Pattaya, while Wyndham Hotels & Resorts provides the hotel brand and operating platform. Wyndham's own global website confirms the operating property at the same address. A buyer should keep those roles separate and verify sale, ownership and investment obligations against the legal entity that actually assumes them in the contract.
Is Wyndham Jomtien Pattaya completed?
Yes. Project materials originally targeted late 2023, and in an official announcement dated 27 January 2024 the company said construction was complete and the development was ready for ownership transfers. The live Wyndham Jomtien Pattaya page on Wyndham Hotels & Resorts' own website is additional evidence that the property is operational. A buyer should still verify the title and transfer status of the individual condominium unit.
Is the 6% annual return for eight years guaranteed to every owner?
The official project website does advertise a 6% annual return for eight years, but it also specifies that the investment programme applies to Building 2. That is a marketed contractual programme, not a universal yield attached to every condominium in the development. Before relying on it, obtain the actual programme agreement and verify the specific unit, responsible entity, calculation basis, term, costs and the effect of termination or resale.
